TECHNICAL FIELD

The claimed invention relates to the field of transport mechanical engineering, particularly to piston engines. The invention may be successfully applied to high-speed or long distance cars, also to cars working in rugged relief and severe climate conditions.

BACKGROUND ART

There are well known internal combustion engines (Georgian Patents GE P 2001 2688 B and GE P 2002 2665 B, Patent of France 2.045.315, US Patent 3,828,740) comprising a body, a cylinder block with pistons having radially arranged combustion' chambers. On the connecting rods linked with pistons there are mounted press rollers interacting with a surface of a rim of oval configuration and creating an engine shaft torque. The drawbacks of these constructions are low efficiency and large dimensions when creating high power engines.

There is known internal combustion engine in accordance with Georgian Patent GE P 2002 2688 B, chosen as an analogue. This analogue has the features similar to the claimed invention, accordingly to the independent claims 1 and 4. The engine comprises a body, a cylinder block positioned concentrically inside of it on rotating bearings with pistons, installed in the cylinder with the possibility of reciprocating movement in radial direction, a mechanism for conversion of movements of pistons into rotating movement of the cylinder block or the body, comprising connecting rods hinged with each piston and fitted with press rollers interacting with races executed on the body, having an oval or other configuration symmetrical about the rotation axis of the block or the body and a system of gas distribution.

From the viewpoint of its essential features the most similar to the alternative design correspondent to the independent claim 7 is an internal combustion engine according to Georgian patent GE P 2005 3515 B, chosen as a prototype. The prototype has the following features similar to the claimed invention: comprises a body, a cylinder block positioned concentrically inside of it on rotating bearings with pistons, installed in the cylinder with the possibility of reciprocating movement in radial direction, a mechanism for conversion of movements of pistons into rotating movement of the cylinder block or the body, comprising connecting rods hinged with each piston, single-armed levers mounted on the cylinder block and press rollers interacting with races executed on the body, having an oval configuration and a system of gas distribution.

The drawback of the prototype is low reliability of construction because of unsteadiness of connecting rods, also large dimensions required for creating according to these schemes a high-power multicylinder engine, that is caused by constructive necessity to arrange combustion chambers near the center, that complicates the design. The drawback is also low efficiency caused by friction in the cylinders from the side forces exerting on the pistons.

For achievement of the said technical results, the internal combustion engine by the second version of the invention (according to the independent claim 4) comprising a body, a cylinder block positioned concentrically inside of it on rotating bearings and comprising at least one piston, installed in the cylinder with the possibility of reciprocating movement in radial direction, a mechanism for conversion of movements of pistons into rotating movement of the cylinder block or the body, comprising connecting rods hinged with each piston and press rollers interacting with races executed on the body, having an oval or other configuration symmetrical about the rotation axis of the block or the body, and a system of gas distribution, envisages the following distinguishing essential features: is fitted with additional press rollers and additional connecting rods hinged with the main ones and all the rollers mounted on them, whereas the additional rollers are positioned in the guiding grooves executed on the cylinder block; additional press rollers are two per each additional connecting rod; one of the additional press rollers is mounted on the same axis as the main press roller and positioned in the guiding groove executed straight-line and slantwise from the radial direction, or curvilinear, but another on the hinge bolt of the main and additional connecting rods positioned in the guiding groove executed along the radial direction.

For achievement of the said technical results, the internal combustion engine by the third version of the invention (according to the independent claim 7) comprising a body, a cylinder block positioned concentrically inside of it on rotating bearings and comprising at least one piston, installed in the cylinder with the possibility of reciprocating movement in radial direction, a mechanism for conversion of movements of pistons into rotating movement of the cylinder block or the body, comprising connecting rods hinged with each piston, single-armed levers mounted on the cylinder block and press rollers interacting with races executed on the body, having an oval or other configuration symmetrical about the rotation axis of the block or the body and a system of gas distribution, envisages the following distinguishing essential features: is fitted with additional connecting rods hinged with the main ones by their one end and with the single-armed levers by the other, whereas hinge bolts of the main and additional connecting rods are fitted with additional press rolls positioned in the guiding grooves executed on the cylinder block, but the main press rolls are mounted on the hinge bolts of the additional connecting rods and single-armed levers; the guiding grooves on the cylinder block are executed along the radial direction; the guiding grooves on the cylinder block are executed straight-line and slantwise from the radial direction, or curvilinear.

There is the following cause-effect connection between the distinctive features of the claimed inventions and the achieved technical results:

In the embodiment of the invention according to the first version, during the stroke the connecting rods have minimal deviation and therefore create minimal side pressure on the pistons in cylinders. This is caused by the offered constructive embodiment, wherein the guiding (mounting for additional press rollers) grooves may be executed not simply straight- line, but also directed along the radial line and the engine can work with that. The ends of connecting rods are reliably positioned in grooves and directed towards the center of engine, but combustion chambers outwards,_, that allows to arrange compactly the most cylinders and decrease the dimensions of the engine, achieve greater power density. The second version of embodiment is the most simple constructively. Due to the presence of additional connecting rods, the main ones do not deviate at all, but guiding grooves of press rollers, serving to each cylinder, are both executed straight-line and provide their function at the expense of mutual slope at an angle optimal for maximurn efficiency.

In the third version all the effects (simplicity of design, increased reliability and efficiency) are achieved due to the presence of additional connecting rods^' and original embodiment of the mechanism for conversion of movements of pistons into rotating movement of the block in the foπn of rod-lever kinematic pairs with press rollers, mounted on their hinge bolts and interacting with synchronizing races. The big arm creates increased torque and power. According to the author's knowledge, the said combination of essential features characterizing the claimed inventions is not known in the prior art and does not explicitly follow from it. Therefore, in author's opinion, the claimed inventions satisfy to "Novelty" and "Inventive level" criteria.

EMBODIMENTS OF THE INVENTION (Industrial applicability)

The essence of the claimed inventions is disclosed by means of graphic materials, showing the following: Figures 1, 2 and 3 show front view of the first, second and third versions of the invention, correspondingly.

According to the Claims, all versions of the internal combustion engine comprise and possess the following common parts and features. The round cylinder block 3 is mounted concentrically in the body 1 on the rotating bearings 2. Cylinders 4 are arranged with their axes along the radial lines, and pistons 5 are positioned inside of them with the possibility of reciprocating movement. Windows 6 and 7 of the gas distribution system (which is not shown on the figure) meant for fuel mixture feeding and fume extraction are executed in the body 1. Spring-loaded rings 8 serve to seal combustion chambers of cylinders 4 and are positioned between the body 1 and the block 3 in grooves executed on the block 3 concentrically with the cylinders 4. On the body 1 there is a working race 9 having an oval or any other configuration symmetrical about the rotation axis of the block 3 (or the body 1), 'for example an epitrochoidal. Connecting rods 10 are hinged with pistons 5. The engine comprises press rollers 11 contacting with the roller running faces of the synchronizing race 9.

In the embodiment of the engine according to the first version of the claimed invention the press rollers 11 are positioned on the opposite ends of connecting rods 10. The additional press rollers 12 are mounted coaxially with the press rollers 11 on the same connecting rods

10 and contact with operating guiding grooves 13 executed on the block 3 straight-line and slantwise from the radial direction, or curvilinear.

The engine according to the second version of the claimed invention is fitted with additional connecting rods 14 hinged with the main rods 10 at one end. Also it is fitted with two additional press rollers 15 per each additional rod 14. One from each pair is mounted on the hinge bolts of the main rod 10 and the additional rod 14, and positioned in straight-line guiding grooves 15 executed on the cylinder block 3 along the radial direction. The other additional press rollers 15 are mounted on the other ends of each additional connecting rod 14 coaxially with the main press rollers 11 and positioned in guiding grooves 16 executed on cylinder block 3 straight-line and slantwise from the radial direction, or curvilinear.

The engine according to the third version of the claimed invention is ,also (like the second one) fitted with the same additional connecting rods 14 hinged with the main rods 10 at one end. The other ends of the additional rods 14 are hinged with single-armed support levers 17 mounted on the cylinder block 3, and press rollers 11 are mounted on these hinge bolts. This engine is fitted with additional press rollers 15 too. They are mounted on the hinge bolts of main 10 and additional 14 connecting rods and positioned in guiding grooves 15 executed straight-line on the cylinder block 3 along or slantwise from the radial direction, or curvilinear. The internal combustion engine functions in the following manner.

While feeding working chambers of cylinder 4 with fuel mixture and executing well- known valve steam distribution cycles through the windows 6 and 7, the pistons 5 start reciprocating movements along with the connecting rods 10. In the first version bf the engine the additional press rollers 12 interact with slanting or curved grooves 13, performing movements corresponding to their tracks together with coaxially mounted main press rollers 11. Therewith, grooves 13 executed on cylinder block 3 serve as support for operating pressure of the main press rollers 11 on races 9 of oval configuration executed on the body 1. This interaction along the slanting roller running face of races 9 creates tangential velocity and induces working rotational movement of cylinder block 3. At that, if the cylinder block 3 is fixed, the working rotational movements performs body 1. Therewith, the created rotation torque depends on slope angle of grooves 13 to radial line, initial and final angles of the connecting rods 10 and on configuration of race 9.

Slope angle or curvature of grooves 13 constructively are selected to be optimal for achieving maximum efficiency depending on several factors: stroke of pistons 5 and their quantity; kind (configuration) of the chosen type of races 9; materials, heat-treatment, velocities and other conditions of contacting surfaces. Therewith, it is preferable to choose minimal slope angle of grooves 13 in order to achieve minimal wobble amplitude of rods 10 and therefore minimal side pressure of pistons 5 on the walls of cylinders 4.

The second version of the engine functions similarly. Therewith, working pressures on the epitrochoidal surface of races 9, inducing rotational movement of cylinder block 3 or body 1, are created by press rollers 11 mounted on the additional connecting rods 14. Therewith, the necessary optimal track and velocities of movement of rollers 11 are provided by angle of mutual slope of the guiding grooves 15 and 16 executed on cylinder block 3.

The third version of the engine functions similarly. At that, press rollers 11, exerting working pressures on the epitrochoidal surface of races 9 and inducing rotational movement of cylinder block 3 (or body 1) are mounted on the hinge bolts of additional rods 14 and single- armed levers 17. The main rod 10, one end of which is held in the guiding groove 15 by means of additional press roller 12, pulls and moves the additional rod 14. Therewith, the necessary optimal track and velocities, of movement of rollers 11 are provided by lengths of rod 14 and lever 17 and location (coordinates) of its pivot pin in the cylinder block 3.

The internal combustion engine according to the claimed invention may be multiply produced and applied with obtaining of complex technical effect which consists in design simplification, lessening of dimensions, increasing power density of power unit (or efficiency), decreasing fuel consumption and reliability growth. Therefore, on author's opinion, the claimed invention satisfies to criterion "Industrial applicability".
