Description

ENGINE USING PERMANENT MAGNET

Technical Field

[1] The present invention relates to an engine for generating an electric power by means of a power generator or driving an engine by using a magnetic force and magnetic poles of a permanent magnet, by alternately changing the poles of opposite permanent magnets for thereby inducing an attraction force and a repulsive force, and by converting the above forces into a rotational motion of a crank apparatus by means of a reciprocation motion of a piston. Background Art

[2] A conventional driving force generation apparatus is classified into a method for generating driving force by using fuels, and a method for generating a driving force by using a natural force such as a wind force, a sun force or something.

[3] First, the method for generating a driving force by using artificial energy source might be classified into a combustion thing and a reaction thing based on energy source.

[4] Generally, the combustion thing is coal, petroleum, gas, bio mess, hydrogen or something, and the reaction thing is uranium 235 and 238, and plutonium 237.

[5] Here, the combustion thing is a carbon or hydrogen fuel which is generally burnt for a good chemical reaction with oxygen in a combustion furnace. The heat generated as it is changed to carbon dioxide or water is used for heating a boiler or the gas in a cylinder is expanded for thereby increasing an inner pressure, so a turbine impeller installed in an exhaust path is rotated as it is discharged into air which has a relatively lower pressure or the fuel is used for obtaining a driving force by using a force which pushes a piston. The reaction thing is a radioactivity fuel. The water in a boiler is expanded and changed to vapor by using a heat generating during a nuclear fission by means of neutron in a nuclear furnace, so the pressure of a boiler is increased for thereby obtaining a driving force generating as the vapor pushes a turbine impeller installed in an exhaust path as it is discharged into air which has a relatively lower pressure.

[6] Next, the method for generating a driving force by obtaining a certain driving force from nature may be classified into a heat energy and a kinetic energy.

[7] First, the heat may be classified into a heat generated by means of sunshine, and a heat generated in an underground.

[8] The method for generating a driving force using sunshine is implemented in such a manner that when sunshine is radiated to a solar cell formed in a semiconductor PN junction, pairs of electrons and pores are generated by means of an optical energy, and the electrons and pores move across a n-layer and a p-layer, so a current is generated, and an electromotive force is generated based on an optical electromotive force effect for thereby generating a current at an externally connected load.

[9] However, it is impossible to generate an electric power during cloud days without sunshine by means of rain, snow, cloud or something, and during nights, and it is impossible to generate a uniform direct current depending on the intensity of sunshine.

[10] The method for generating a driving force by using a geothermal energy is directed to generating an electric power by driving a generator as a turbine is rotated by means of the force generated as heat from magma is transferred, and high temperature vapor is outputted.

[11] The geothermal generation is a relatively simple and has a high driving rate, and a surplus heat can be supplied to local area energy.

[12] However, the area used for generating a geothermal energy is very limited because of a combination with environment and an earthquake.

[13] The method for generating a kinetic energy which might be obtained from nature may be classified into a flowing force(wind force) of air, and a flowing force of water(water force). The method for generating a driving force by using a wind force is directed to generating an electric power in such a manner hat the force generated by natural air drives a propeller blade, and a rotational force is obtained, and the rotational speed is increased by using an acceleration apparatus. The wind po9wer generation is capable of generating electric power by rotating an electric generator at a high speed irrespective of the speed of wind, so it is needed to tilt the blades of a windmill depending on the speed of wind. In other words, a rotational force is obtained by means of a rotor based on an aero-dynamic characteristic of a kinetic energy that air has, and the rotational force is converted into a mechanical energy for thereby generating an electric power by using an electric generator.

[14] The method for generating a driving force using a water force is directed to producing a kinetic energy of water and generating an electric power, which basically uses a water level difference formed by making a dam or a wall. A dam is built in a river or a lake for thereby storing water. A water gate is open, and stored water flows, and a turbine is driven by the pressure generating when the water flows for thereby generating electric power. A seawall might be installed in a downstream or an entrance of a bay where there is a strong tide, and then a water level difference electric power and a water gate are installed, and a sea water storing area is made. The turbine is driven by a water pressure formed between the seawater storing area and sea based on an operation of a water gate, or the turbine is driven by using a flowing force of the tide. [15] The above methods of using various energy sources have problems for obtaining energy sources and processing the obtained energy source, and it is needed to resupply the energy source after it is consumed, and some basic problems occur due to the changes in energy sources. So, a lot of problems occur, which leads to a low economical efficiency. For example, a widely used internal combustion engine uses gasoline or diesel finely processed through a refining process and supplied through a cylinder for burning the same. The heat generating along with carbon dioxide is used for expanding air in the cylinder, and the interior of the cylinder becomes a high pressure state, and the piston is driven by receiving the force generated when the high pressure is discharged into the low pressure cylinder, so a driving force of the piston is transferred to a crank through a connecting rod for thereby generating a rotational force.

[16] In case of the internal combustion engine, the piston moves back by means of a backward force applied to the piston depending on a pressure change of the interior of the cylinder, and it should move forwardly into the interior of the cylinder in order for the piston to receive a backward force again, so part of the rotational force of the crank obtained during an expansion stroke might be lost during an exhaust stroke, a suction stroke and a compression stroke. Namely, the internal combustion engine is formed of one cycle consisting of suction, compression, expansion and exhaust. The driving force is generated only in the expansion stroke, whereas a lot of driving force loss occurs during the exhaust, suction and compression strokes. In order to continuously generate a high pressure in the interior of the cylinder, it is needed to continuously supply a certain fuel which has high combustion efficiency and can be easily burnt, and a precise ignition should happen at the top dead point during the compression stroke, so heat expansion efficiency is enhanced by means of the combustion, and a high pressure state can be instantly made in the interior of the cylinder, and a reliable backward force might be applied to the piston. It is needed to exhaust the heat and carbon dioxide from the interior of the cylinder which has passed the heat expansion process, and new air containing oxygen needed for the following combustion is inputted into the interior of the cylinder, so the pressure of the interior of the cylinder becomes lower. The driving force generated by means of the internal combustion engine is less than 20% as compared to the input energy amount of the needed fuel due to its heat loss. The heat energy engines, which need chemical, thermal, pressure, mechanical, driving force, and electric and dynamic processes and several conversion apparatuses, and transfer apparatuses, are not reasonable due to their structural dynamics, and have inefficient driving force generation methods and are not friendly to environment.

[17] The above conventional engines have many problems in the fuel inputted for generating a driving force, and in a method for generating an energy from the fuel, and in a mechanical loss (friction or heat generation), so subsequently the energy obtained and used through the above processes is less.

[18] In order to overcome the above problems, the same applicant as the present applicant filed Korean patent application number 2006-92777 (Title: self- amplification engine) and Korean patent application number 2007-27098 (Title: magnetic-amplification piston engine). In the above applications, an engine is driven by using an attraction force and a repulsive force which correspond to the magnetic poles of the permanent magnet and the electromagnet.

[19] In the above applications, the electromagnet and permanent magnet are installed in the rotor and the stator with their poles being opposite to each other, so the rotor rotates by means of a repulsive force between both the magnets, and a driving force is generated through a rotary shaft rotating along with the rotor. In another embodiment, the electromagnet and the permanent magnet are provided in the reciprocating mover and the stator with their poles being opposite to each other, and a repulsive force is continuously generated between both the magnets, so the piston, which is a reciprocating mover, straight reciprocates by means of the repulsive force between both the magnets, and the straight motion is converted into the rotational motion through the crank, and a desired driving force is obtained through the rotary shaft.

[20] However, the above applications use the magnetic force of the permanent magnet, so it is possible to generate a driving energy greater than the driving force of the electromagnet, which leads to much advantages, but the electromagnet has a weak magnetic force as compared to the permanent magnet, and it is needed to continuously input an electrical energy for exciting the electromagnet and alternating the poles of the excited electromagnet. A lot of electric power should be supplied due to its poor efficiency, and it is needed to further increase the energy efficiency. Disclosure of Invention Technical Problem

[21] Accordingly, it is a first object of the present invention to provide an engine which is capable of obtaining a reciprocation driving operation by using only the magnetic force of a permanent magnet even when a supply of an electrical energy is disconnected, namely, an electric energy is needed only for an initial start of the engine.

[22] It is a second object of the present invention to provide an engine in which a power generator is driven by means of part of the driving force generated as a main engine is driven, and induced electricity is accumulated and used when starting the engine. Very small amount of electric energy is needed for starting the engine.

[23] It is a third object of the present invention to provide an engine which is capable of generating a new driving force without inputting a fuel for a long time by using a magnetic force of a permanent magnet as compared to a conventional driving force generation engine which is driven only when a fuel is continuously supplied.

[24] It is a fourth object of the present invention to provide an engine for obtaining a desired driving force in which a permanent magnet having a strong magnetic force is adapted, and the permanent magnets are installed with their magnetic poles being opposite to each other, and one side permanent magnet pole is alternately changed, so the different pole confrontations are made between the poles, and an attraction force and a repulsive force are generated, which leads to a straight reciprocation through the piston apparatus, and it is changed to a rotation motion of the crank for thereby generating a driving force.

[25] The reliable magnetic poles of the permanent magnets and their strong magnetic forces are used as a core member which is an important element in a power generator or a motor. However, a means for using the permanent magnet as a driving force source is not yet developed. So, in the present invention the permanent magnets are used as the important elements of the fuel and mechanical apparatuses for using the permanent magnets as a driving force source.

[26] The present invention comprises a mechanical apparatus in which the permanent magnets are adapted as a key element of the fuel and mechanical apparatus for using the permanent magnet as a driving force source, and the permanent magnets are arranged opposite to each other, so the poles corresponding relationship is set between the permanent magnets, a mechanical apparatus for converting a magnetic attraction force and a magnetic repulsive force into a reciprocation motion as the poles are alternately arranged, a mechanical apparatus which converts a reciprocation motion into a rotational motion, an operation and control apparatus for operating and adjusting the mechanical apparatuses, a mechanical apparatus for transferring the driving force generated as the engine operates, and a power generator for converting the generated driving force into power energy. Technical Solution

[27] To achieve the above objects, there is provided a driving force generation engine using a magnetic force and magnetic poles of a permanent magnet which comprises a frame which supports an apparatus; a rotary shaft which is rotatably supported with respect to the frame; a motor for rotating the rotary shaft in one direction; a rotation rum member which is fixedly engaged to the rotary shaft; a plurality of first permanent magnets which are arranged in multiple rows at regular intervals in an axial direction on a surface of the rotation drum member, and are engaged with the neighboring poles being different depending on their circumferential direction; a crank shaft which is installed parallel with the rotation drum member and is rotatably installed with respect to the frame, and is equipped with a plurality of crank pins corresponding to the arrangement tiers of the first permanent magnets; a plurality of pistons which are connected with the crank pins of the crank shaft through a connecting rod and reciprocate toward the rotation drum member in a right angle direction with respect to the shaft; a plurality of second permanent magnets which are engaged at the front end of each piston, so an attraction force or a repulsive force occurs between the first permanent magnets of the rotation drum members which are installed opposite to each other in the bottom dead point or top dead point of each piston; and a guide apparatus which guides a reciprocation straight movement for a reliable movement of the pistons.

[28] The crank shafts, pistons, and second permanent magnets are installed on an outer circumference of the rotation drum member in a radial direction by at least two for thereby generating a rotational driving force.

[29] The crank shaft rotates in one direction through a one directional clutch bearing.

[30] The rotary shaft and crank shaft cooperatively operate with gears, so the crank shaft keeps one direction rotation.

[31] There is provided a braking apparatus for braking the rotation of the rotary shaft.

[32] There is provided a clutch apparatus for intermitting an operation that the rotational force of the motor is transferred to the rotary shaft.

[33] The first permanent magnets of each tier of the rotation drum member are deviated from each other for a phase difference based on the position difference of each piston.

[34] A crank shaft is movably installed in a right angle direction with respect to the shaft for adjusting the intervals for an opposite arrangement between the first and second permanent magnets in the top dead points of the pistons.

[35] A base plate is fixed in a slide movement and a movement position in a right angle direction with respect to the shaft toward the rotation drum member, and both sides of the crank shaft are rotatably installed by means of the support member upright installed in the base plate.

[36] The rotation drum member includes a hollow inner drum coaxially inserted into the rotary shaft, a plurality of outer drum fixedly alternately inserted into an outer circumference of the inner drum, a spacing ring, and a cover which is closely contacted with both sides of the inner drum and fixes the inner drum to the rotary shaft and covers the whole portions of the outer drum, wherein the first permanent magnets are engaged on an outer circumference of the outer drum in a circumferential direction.

[37] The outer drum has a polygonal outer circumference, and a T-shaped fixing protrusion is fixed in each apex in a radial shape, and a first permanent magnet is inserted into the engaging groove member formed between the fixing protrusions from their open side surfaces.

[38] The guide apparatus includes upper and lower fixing guide rails for supporting all pistons at upper and lower sides and guiding a straight motion; an upper cover for fixedly supporting all upper fixing guide rails; and upper and lower driving rains which are protrude-engaged with the upper and lower fixing guide rails for a slide movement, and are fixed in the upper and lower sides of the pistons, wherein the lower fixing guide rails are fixedly installed in the base plate.

[39] A bearing is disposed in a protrusion-engaging part of the upper and lower guide rails and the upper and lower driving rails.

[40] The guide apparatus includes left and right fixing guide rails which support both sides of all pistons and guide a straight movement of each piston; and left and right driving rails which are protrude-engaged with the left and right fixing guide rails and are protruded from both sides of the pistons, wherein the left and right fixing guide rails are fixed on the base plate.

[41] The first and second permanent magnets cover the portions except for their surfaces with a multiple-layer magnetic plate.

Advantageous Effects

[42] According to the present invention, the permanent magnets with their magnetic poles being alternately disposed are arranged in a cylindrical rotation drum, and a permanent magnet is engaged at a front end of the piston which straight reciprocates. So, when the rotation drum member rotates, the poles of the permanent magnets of the rotation drum member corresponding to the permanent magnets of the front end of the piston are alternately changed for thereby generating an attraction force and a repulsive force, which leads to reciprocating the piston and rotating the crank shaft for thereby obtaining a rotational force. It is possible to generate a reliable clean electric energy by driving a motor apparatus or a power generator by using the rotation force of the crank shaft. Since the permanent magnets continuously function as the fuel, it is not needed to input fuel while not causing any environment pollution. Since the present invention is not directed to an apparatus which generates heat energy based on combustion or chemical reaction, a heat loss does not occur, and less mechanical friction occurs, and a driving force does not lose, and a mechanical structure is simple, and a high efficiency and economical effect can be obtained. Since a thermal expansion medium such as water or air is not needed, an external low pressure condition is not needed, which leads to generating a high driving force. The present invention can be well adaptable to the engines of various apparatus for the use in power generation, ship, industry or something.

[67] In the present invention, there is provided a driving force generation engine using a magnetic force and magnetic poles of a permanent magnet, comprising a frame which supports an apparatus; a rotary shaft which is rotatably supported with respect to the frame; a motor for rotating the rotary shaft in one direction; a rotation rum member which is fixedly engaged to the rotary shaft; a plurality of first permanent magnets which are arranged in multiple rows at regular intervals in an axial direction on a surface of the rotation drum member, and are engaged with the neighboring poles being different depending on their circumferential direction; a crank shaft which is installed parallel with the rotation drum member and is rotatably installed with respect to the frame, and is equipped with a plurality of crank pins corresponding to the arrangement tiers of the first permanent magnets; a plurality of pistons which are connected with the crank pins of the crank shaft through a connecting rod and reciprocate toward the rotation drum member in a right angle direction with respect to the shaft; a plurality of second permanent magnets which are engaged at the front end of each piston, so an attraction force or a repulsive force occurs between the first permanent magnets of the rotation drum members which are installed opposite to each other in the bottom dead point or top dead point of each piston; and a guide apparatus which guides a reciprocation straight movement for a reliable movement of the pistons.

[68]

Mode for the Invention

[69] The construction of the present invention will be described with reference to the accompanying drawings.

[70] In the drawings, reference numeral 1 represents a driving force obtaining engine according to the present invention, and the driving force obtaining engine 1 has a rotary shaft 3 which is rotatably supported by means of a support member 2A on a frame 2, and a motor 4 is installed in one side of the rotary shaft 3 for rotating the rotary shaft 3 in one direction, and the motor 4 drives the rotary shaft 3 along with pulleys 5 and 6 and a V-belt 7.

[71] The motor 4 rotates in one direction, and as shown in Figure 6, an electronic or mechanical type clutch apparatus 8 may be installed in the rotary shaft 3 for intermitting a rotational driving force, or as shown in Figure 2, a braking apparatus 9 may be installed for preventing the rotation of the rotary shaft 3, and the clutch apparatus 8 and the braking apparatus 9 might be selectively installed or might be installed along with the same.

[72] A rotation drum member 10 is fixed in the rotary shaft 3 for thereby rotating along with the rotary shaft 3. The rotation drum member 10 comprises a longitudinal cylindrical inner drum 11 which might be fixed in the whole portions of the rotary shaft 3 or coaxially inserted into the same 3, a plurality of hollow outer drums 14 which are engaged into the protrusions 12 and 13 of the outer surface of the inner drum 11, a spacing ring 15 which is inserted between the outer drums 14 for keeping a certain space and fixed in the rotary shaft 3 by means of the protrusions 12 and 13, and a cover 16 for covering both side surfaces of the inner and outer drums 11 and 14 for fixing the inner drum 11 to the rotary shaft 3. The inner drum 11 is preferably provided with a hollow portion for decreasing the weight, and the covers 16 of both sides are fixed in the inner drum 11 and the rotary shaft 3 by means of screws.

[73] The outer surface of the outer drum 14 is formed in a 12-angled shape, not in a circular shape, and a first hexagonal permanent magnet 20 is installed in an engaging groove portion 19 formed between the fixing protrusion 18 of a T-shaped member(when viewing in an axial direction) radial-protruded from each apex as it is inserted into its open side.

[74] A plurality of 12 permanent magnets 20 are arranged in a circular shape at an interval by means of the fixing protrusion 18 in an outer drum 14 of the rotation drum member 10 along its outer circumference surface. At this time, the first permanent magnet 20 is engaged into the engaging groove member 19 along a circumferential side in such a manner that the poles between neighboring magnets are alternately changed, namely, when the pole of one surface is a positive value, the poles of the surface of the permanent magnet positioned in its both sides is a negative value which is opposite to the same.

[75] In addition, the outer drums 14 are arranged in multiple tiers along an axial direction with respect to the spacing ring 15, and when they are exploded along an outer surface of the outer drum 14 in a plane shape, the first permanent magnets 20 are arranged in a matrix shape in vertical and horizontal directions, and since the spacing rings 15 block the openings of both sides of the engaging groove member 19 inserted with the permanent magnets 20, the first permanent magnets 20 are not escape unless the spacing ring 15 and the outer drum 14 are not disengaged.

[76] A plurality of crank shafts 21 are rotatably supported along a circumference of the rotation drum member 10 in one direction, preferably, in both directions of the rotary shaft 3, and the crank shaft 21 includes the crank pins 22 by the number of the arranging tiers of the first permanent magnets 20, in details, by the number of the outer drums 14. In the embodiment shown, there provided six outer drums 14, so six crank pins 22 are provided in opposite sides, respectively. A 6-cylinder crank shaft 21 in which two three-cylinder crank shafts having three crank pins 22 with 120° phase difference are connected in series.

[77] A piston 24 is connected with each crank pin 22 of the crank shaft 21 with a connecting rod 23 being disposed between the same, and a small end 231 of the connecting rod 23 is engaged to the piston pin 243 of the piston, and the large end 232 of the connecting rod 23 is engaged to the crank shaft 21, and the crank shaft 21 rotates by reciprocating the piston 24. The above construction is the same as the conventional internal combustion engine. A guide apparatus 25 having the same guide function as a conventional cylinder is provided instead a cylindrical cylinder for guiding a straight reciprocation motion of the piston 24 as shown in Figure 12.

[78] The piston 24 has a four-angle cross section, and a second permanent magnet 26 is engaged in its front end as being opposite to the first permanent magnet 200 by using a fixing cover 244. When the piston 24 reaches the top dead point (here, the top dead point means when the piston is nearest the rotation drum member, and the bottom dead point means when it is furthest), the same pole as the pole of the second permanent magnet 20 of the outer drum 14 is obtained, and it pushes back to the bottom dead point by means of the repulsive force, and in a state that the piston 24 is positioned in the bottom dead point, the rotation rum member 10 rotates by one pitch, and the opposite pole is changed, and the first permanent magnet 20 having the pole opposite to the second permanent magnet 26 of the piston 24 positioned in the bottom dead point is positioned in the opposite side, so a suction force is generated between both magnets, and the piston 24 is moved to the top dead point, and the crank shaft 21 rotates.

[79] However, the piston 24 is guide by the guide apparatus shown in Figure 13, so that it only reciprocates in a straight direction (right angle with respect to the axial direction) without moving along with the motion of the connecting rod 23. The guide apparatus 25 includes upper and lower fixing guide rails 251 and 252 which surface-contacts with the upper and lower sides of all the pistons 24 and guide a slide movement in the straight direction toward the rotation drum member 10, and upper and lower driving rails 241 and 242 (protrusion from upper and lower sides of the piston) which move along the guide of the upper and lower fixing guide rails 251 and 252. Here, six upper and lower fixing guide rails 251 and 252 are provided in the upper and lower sides, and the upper fixing guide rail 251 is fixed to the upper cover 27 which crosses the apparatus in the direction parallel with the rotary shaft, and all lower fixing guide rails 252 are fixed in the base plate 32, and the upper and lower fixing guide rails 251 and 252 and the upper and lower driving rails 241 and 242 are assembled to the protrusion(or dove rail) engaging portion 28 for a reliable slide movement with a LM bearing 29 being disposed therein. The upper cover 27 for fixedly supporting the upper fixing guide rails 251 are formed in a box shape frame with their both ends being fixed to the base plate 32 with bolts through the support rod 271.

[80] In addition, the fixing guide rails 251 and 252 and the driving rains 241 and 242 might be installed in upper and lower sides, respectively, or might be installed at both sides of the piston 24. In this case, as shown in Figure 14, the left and right fixing guide rails 25B and 25B are arranged in both left and right sides of the piston 24, and the left and right fixing guide rails 25B and 25B are fixed in the base plate 32, and the left and right rails might protruded from both sides of the piston with the portion 28 engaged for a guide being disposed along with bearings. So, the upper cover might be omitted.

[81] As shown in Figure 15, the first and second permanent magnets 20 and 26 are engaged to the rotation drum member 10 and the piston 24 after a thin two-layer steel plate 30 made of a magnetic material covers five surfaces except for the surfaces 2OA and 26 A which use the magnetic force as shown in Figure 15.

[82] When the surfaces are covered with the two-layered steel plate 30, a magnetic force does not leak through the double steel plate 30, and is discharged through the exposed surfaces 2OA and 26A for obtaining a stronger magnetic force.

[83] The crank shaft 21 might be directly supported through the support member 31 which is vertically disposed in the frame 2. As shown in Figures 1 and 17, the base plate 32 is mounted as being supported by means of the frame 2, which base plate ca slide in a reciprocation direction(toward the center line of the rotary shaft in an angled direction with respect to the crank shaft) of the piston 24 on the frame 2, and the support member 31 is vertically installed in the base plate 32, and both ends of the crank shaft 21 are rotatably supported in the support member 31 with the bearing being disposed therein. The base plate 32 is provided with an elongated hole 33 in a slide movement direction angled to the shaft for fixing the same in a moved position on the frame 2. It is engaged to the frame 2 with bolts and nuts. When it is needed to adjust the opposite intervals at the top dead points between the first and second permanent magnets 20 and 26 of both sides, the bolt 34 is loosened, and the base plate 32 slides in a range of the elongated hole 33. When the bolt and nut 34 are rightly tightened in the moved position, the base plate 32 is fixed in the frame 2.

[84] The crank shaft 21 might be constructed so it can rotate in one direction along with a one direction clutch bearing(not shown). As shown in Figure 4, the rotary shaft 3 and the crank shaft 21 are connected in a cooperation structure(if necessary, an idle gear 37 might be disposed) through the gears 35 and 36, so the crank shaft 21 rotates in one direction like the rotary shaft 3 which rotates in one direction by means of the motor 4.

[85] A power generator 41 is connected with the shaft 37 A of the idle gear 37 engaged with the gear 36 of the crank shaft 21 through pulleys 38 and 39 and a V-belt 40. When the crank shaft 21 rotates in one direction, the power generator 41 is driven for thereby generating electric energy. A transmission might be connected in an end of the crank shaft 21, and wheels are rotated. So, the present invention might be used for various driving force mechanisms such as a vehicle engine or something.

[86] In addition, at least one crank shaft 21 is installed (here, at least two pistons 24 and crank pins 22 are disposed with respect to one crank shaft, and the first permanent magnet is arranged in at least two rows while corresponding to the number of pistons, and when one piston receives a forward moving force, the other piston receives a propelling force), and more preferably as shown in Figure 2, two crank shafts 21 are symmetrically installed at both sides of one rotary drum member 10 while being opposite to each other (here, at least one piston pin and at least one piston are provided in each crank shaft, and when the piston of one crank shaft receives a forward moving force, the piston of the other crank shaft receives a backward moving force), or if a space for installing three or four at 120° or 90° is available, five or eight might be installed in a radial shape, namely, multiple numbers might be installed.

[87] The operation of the apparatus according to the present invention will be described with reference to Figures 18 through 21.

[88] The operation will be described along with the pistons 3 and 4, and the reference character A represents a right side, and B represents a left side, and reference numeral 3 of the end of the reference represents a third piston or a third crank pin, and the numeral reference 4 of the end represents a fourth piston or a fourth crank pin. CP represents a crank pin, and the first permanent magnets 20 are given Al through 112.

[89] For starting the engine, the clutch apparatus 8 is connected, and battery power is supplied, and the motor 4 is driven. The rotational force of the motor 4 is transferred to the rotary shaft 3 through the V-belt 7 and pulley 6. The rotary shaft 3 and the rotation drum member 10 slowly rotate.

[90] Figure 8 shows the construction of the crank shafts 21 A and 2 IB, and it can be assumed that the third right crank shaft 21 A and the fourth pistons 24A3 and 24 A4 are positioned on the top dead point(as shown in Figure 2, the second and fifth crank pins CPA2 and CPA5 are positioned in the 120° rear upper side, and the first and sixth crank pins are positioned in the 120° rear lower side), and the third and fourth pistons 24B3 and 24B4 of the third and fourth pistons 24A3 and 24 A4 are positioned in the bottom dead point, the first permanent magnet 20Al of the same pole as the second permanent magnets 26 A3 and 26 A4 of the third and fourth pistons 24A3 and 24 A4 is opposite, so the third and fourth pistons 24B3 and 24B4 are retracted by means of a repulsive force, and the crank shaft 21A rotates. Since the third and fourth pistons 24B3 and 24B4 of the left crank shaft 2 IB are positioned on the bottom dead point, and the opposite magnets 26A7 and 26B3(26B4) have opposite poles, the third and fourth pistons 24B3 and 24B4 are pulled toward the rotation drum member 10, and the crank shaft 2 IB rotates.

[91] Figure 19 view a state that the crank shafts 21 A and 2 IB are rotated in counterclockwise directions by 120°. The third and fourth pistons 24A3 and 24 A4 of the right side are in the course of retraction, and the third and fourth pistons 24B3 and 24B4 of the left side are in the course of forward movement. The second and fifth pistons 24A2 and 24A5 and 24B2 and 24B5 are positioned in the state of Figure 18, and a repulsive force(left piston) and an attraction force(left piston) are formed between the opposite first permanent magnets. When the crank shafts 21 A and 2 IB keep rotating, and then the crank shafts 21A and 21B rotate 240° from the recent state, the third and fourth pistons 24A3, 24A4, 24B3 and 24B4 and the crank pins CPA, CPB are positioned as shown in Figure 20, and in this state, the first and sixth pistons 241 A, 24A6, 24Bl and 24B6 are positioned on the top dead point and the bottom dead point, respectively.

[92] The first and sixth pistons 24Al, 24A6 and 24Bl, 24B6 receive attraction force and repulsive force, respectively, and the crank shafts 21 A and 2 IB keep rotating, and as shown in Figure 21, when the third and fourth pistons 24 A3, 24 A4 and 24B3, 24B4 are positioned on the top dead point and the bottom dead point, respectively, the crank shafts 21A and 21B finishes one rotation of 360°, and the rotation drum member 10 rotates once, and the poles of the magnets change 12 times, and the crank shafts 21A and 2 IB rotate four times.

[93] When the fist and sixth pistons CPAl and CPA6 of the right side are positioned on the top dead point, the third and fourth crank pins CPA3 and CP A4 are positioned on the 120° rear upper side(240° position in the rotation direction) and approach the top dead point, and the second and fifth crank pins CPA2 and CPA5 are positioned in the 120° rear lower side past the top dead point, and approach the bottom dead point as shown in Figure 20. Since the second permanent magnet of the first and sixth pistons are opposite with the same poles as the first permanent magnet, the first and sixth pistons are pulled toward the bottom dead point by means of a strong repulsive force, and as the first and sixth pistons are pushed toward the bottom dead point, the crank shaft 21 A keeps receiving the rotational driving force.

[94] For example, the crank shafts 21A and 21b rotate 4 times as the rotation drum member 10 rotates one time since 12 permanent magnets are alternately engaged on a circumference surface of the rotation drum member 10 with six positive poles and six negative poles being alternated.

[95] However, the revolution of the crank shafts 21A and 21B might be changed depending on the number of the pistons, the arranged angle(phase difference) of the piston pin and the installation intervals of the first permanent magnets arranged along a circumference of the rotation drum member.

[96] Here, the driving force capable of rotating the rotation rum member 10 is relatively small, but a strong attraction force and a repulsive force can be obtained by means of the permanent magnets having the very strong magnetic forces. With a relatively small energy input, it is possible to obtain a relatively large rotation driving force from the crank shaft. Electric power is obtained by means of the driving force from the crank shaft 21, and the rotation rum member 10 can be rotated by using only part of the generated power. When the crank shaft 21 and the rotary shaft 3 are connected in the gear structures 35, 36 and 37, only a supply of the initial motor driving force is needed for driving the rotary shaft 3, and once the engine is driven, it is possible to keep driving the engine without a power supply from the motor 4.

[97] When two magnets of different poles are attached by means of the attraction force, a large force is needed for separating two permanent magnets by supplying a force in a right angle direction with respect to their junction surfaces, and it is possible to easily separate two magnets, which are strongly attached, with a very small force when providing a force in a deviated tangential direction with respect to the junction surface. In the present invention, when the rotation drum member is rotated by engaging a permanent magnet in the rotation drum, the permanent magnet of the rotation drum member approaches in a tangential direction with respect to the permanent magnet of the piston, and retracts in a tangential direction, so that it is possible to drive a rotation drum member with a very small power input. The approach and escape in the tangential direction is the biggest feature of the present invention. In the present invention, there is provided a cooperation structure by connecting the rotary shaft 3 and the crank shaft 21 with the gears 35, 36 and 37, it rotates along with the rotation shaft 3 when the crank shaft 21 rotates. So, it is not needed ton input an additional driving force for driving the rotary shaft 3.

[98] When the crank shaft 21 rotates, electric power might be generated through the power gene rator 41 or might be accumulated, and the rotation force might be used as a driving force source for driving various apparatuses such a vehicle or something. The time for consuming the magnetic force of the permanent magnet is very long, so it is possible to generate a desired driving force for a very long time without inputting an additional cost.

Industrial Applicability

[100] According to the present invention, the permanent magnets with their magnetic poles being alternately disposed are arranged in a cylindrical rotation drum, and a permanent magnet is engaged at a front end of the piston which straight reciprocates. So, when the rotation drum member rotates, the poles of the permanent magnets of the rotation drum member corresponding to the permanent magnets of the front end of the piston are alternately changed for thereby generating an attraction force and a repulsive force, which leads to reciprocating the piston and rotating the crank shaft for thereby obtaining a rotational force. It is possible to generate a reliable clean electric energy by driving a motor apparatus or a power generator by using the rotation force of the crank shaft. Since the permanent magnets continuously function as the fuel, it is not needed to input fuel while not causing any environment pollution. Since the present invention is not directed to an apparatus which generates heat energy based on combustion or chemical reaction, a heat loss does not occur, and less mechanical friction occurs, and a driving force does not lose, and a mechanical structure is simple, and a high efficiency and economical effect can be obtained. Since a thermal expansion medium such as water or air is not needed, an external low pressure condition is not needed, which leads to generating a high driving force. The present invention can be well adaptable to the engines of various apparatus for the use in power generation, ship, industry or something.
