With reference to above-mentioned accompanying drawing, reference number 1 is indicated an internal-combustion engine usually, and this internal-combustion engine comprises that a cylinder or cylinder body [2] and are installed in the cylinder body [2] and make rotor rotated, and this rotor comprises respectively and is marked as the double rotor member that [3] and [4] are arranged to cooperatively interact.Each rotor component rotate together with corresponding axle [5,10] rigidly, every axle on working be marked as [7] usually and comprise that two opposed ellipse garden gear corresponding driving mechanisms of intermeshing link to each other.Rotor component [3] comprises the cylindrical holder [8] of central authorities, and relative fixture block or sector unit [9,9 '] therefrom extend on axial plane so that stretch out from holder [8] on diameter.Similarly, rotor component [4] is equipped with a central cylindrical shape holder [10] that similarly replenishes mutually with holder [8] and has on diameter relative and in the axial direction with respect to the fixture block or the sector unit [11,11 '] of holder [10] extension.

With two rotor components [3] and [4] be mounted to be installed in axle [5] hollow or tubular shafts or holder [10] in its fixture block [9,9 ' and 11,11 '] thereby extension cooperatively interact its corresponding holder [10 and 8] be close together mutually, thereby form two coaxial rotor assemblies.

Rotor assembly is dressed up and can be rotated freely in cylinder or cylinder body [2], and rotor assembly also can directly be connected with driving mechanism [7] by axle [5 and 10].

Under the condition that assembles, rotor assembly has been determined a series of chamber in cylinder body [2].Such chamber is the inner space, wherein can produce the petrolic circulation stroke of heat-absorbing type of for example foru cycle engine as shown in Figures 2 and 3.

In power stroke, fixture block or sector unit [9,9 ' and 11,11 '] be arranged to as shown in Figure 3 one with another relation of relatively arranging.

Fuel combustion make fixture block [9] with acceleration travel forward (clockwise direction) finish up to exhaust stroke.Simultaneously, be linked to be whole fixture block [9 '] with it and in whole compression stroke, be subjected to same acceleration.Similarly, assembly [4] slows down when assembly [3] quickens, and therefore when assembly [4] passes through its power stroke, it will be accelerated, and assembly [3] then correspondingly slows down.

Difference on this rotational speed between assembly [3] and [4] depends on that to obtain basis the specific order of the degree of eccentricity of ellipse garden gear changes the power of its volume, exhaust, air-breathing and pressing chamber owing to arrange have ellipse garden gear driven mechanism [7] just can make it become possibility.For each whole circle rotation of each rotor assembly [3 and 4], produced the four-stroke of for example air-breathing, compression, power and exhaust stroke and a spark plug [12] that makes the main fuel ignition has been housed.

As Fig. 5,6 or likes wherein identical with the parts of Fig. 1-4 with 7(have identical reference number) shown in embodiment comprise the driving mechanism [13] that contains two identical train of gearings.More particularly, hollow shaft [10] stretches out and is designed to from cylinder or cylinder body [2] and drives first train of gearings, wherein useful key is installed in the garden shape gearwheel [14] on the hollow shaft [10], mesh and be installed in driving gear 15 on the axle journal of the parallel rotatable jack shaft of axis y-y of its axis X-X and axle [5 and 10] or auxiliary axis [16] with gearwheel [14], be installed in that axle [16] go up to be done rotation and driving gear [15] first ellipse garden profile of tooth [17] of rotation together rigidly, and be installed in the second ellipse garden gear [18] on its axis Z-Z and the y-y output shaft [19] parallel with the X-X axle with key.The axle [5] of extending by whole hollow shaft [10] is stretched out both from cylinder [2] and spool [10], and is arranged to drive second train of gearings.If desired, when axle [5] and hollow shaft [10] on time, axle [5] can be outstanding from cylinder [2] in its end away from hollow shaft [10].In this case, motor 1 is nibbled between the train two.

Second train of gearings comprises a garden shape gearwheel [20] that rotates with axle [5] rigidly, one be installed in gearwheel [20] engagement and with key in the middle of or the driving gear [21] on the auxiliary running shaft [16], one also is to be installed in ellipse garden gear [22] on the axle [16] and one with key to be installed in the second ellipse garden gear [23] on the axle [19] with key.The ellipse garden gear [22 and 23] of the ellipse garden gear [17] of first train of gearings and [18] and corresponding second train of gearings is the same and after it is calibrated along its main shaft, and they have 180 ° phase difference.

Axle [16] also can be a non-rotary axle, and in this case, gear [15,17 and 21,22] can be installed in axle and upward rotate, and with gear [17] rotation, gear [21] rotates with gear [22] gear [15] rigidly rigidly.At spur wheel [14,15] and [20,21] drive ratio between is that 1: 2 driving mechanism [13] rotates meeting generation rotor [3 for each whole circle through 360 ° of output shaft [19], 4] many relative acceleration and deceleration, thereby caused at fixture block or sector unit [9,9 ' and 11,11 '] between corresponding many volumes on variation, thereby provide complete air-breathing, the compression of two of a typical foru cycle engine, power and exhaust stroke circulation.If in axle [5,10] and the driving between the gear of ellipse garden to connect be to should be 1: 4 mutually by its drive ratio certainly, two pairs of garden generating gears [14,15 and 20 of 1: 6 grade, 21] words, if increase to for example 4 accordingly with the number of rotor fixture block or sector unit [9,9 ' and 11,11 '], the words of 6 grades, then the period of motor can be higher than 2 times, and promptly 4 times, 6 times or the like (but all being even number in all cases).

After two spur wheels were omitted in such shown in the embodiment of Fig. 1, rotary engine can be used as compressor or pump, and this is because the rotation of every circle produces an acceleration stroke and a deceleration stroke.In other words, it can replace four-stroke with two-stroke.In this case, axle [19] is an output shaft, and axle [5,10] is for being designed to drive expediently the rotor that has a sector unit or fixture block [9 or 11].Directly the degree of eccentricity with ellipse garden gear is relevant for the end subtended angle of the fixture block of rotor assembly [9,9 ' and 11,11 '], and this degree of eccentricity is also relevant with the Maximum Torque of motor [1] again.Therefore, as an example, if α is the interior angle between two straight lines of the intersection point in the ellipse garden of the corresponding joint with it of the rotating center that connects each ellipse garden gear, β is the exterior angle of (Fig. 6) between these same straight line, if drive ratio is 1: 2 or is 1: 4 then subtended angle is α/4 and β/4 or the like as this ratio, then the respective end portions subtended angle of sector unit or fixture block [9,9 ' and 11,11 '] is respectively α/2 and β/2.

In drive ratio is 1: 4 o'clock, and each causes rotor axis [5 and 10] alternately to carry out four acceleration and four deceleration strokes through 360 ° whole circle rotation, so in fact produces the continuous and uniform motion of axle [19].Angle α can not have identical value with β because otherwise they just without acceptance of persons, thereby does not correspondingly have and quickens and deceleration (no relative anti-phase).

Fig. 5-7 has also showed the specific particular design of a hollow mandrel [10], this axle extend near gearwheel [20] a bit, it will have a terminal axle sleeve or a bearing [25] that is used for axle [5] there.

If needed, fixture block or sector unit [9,9 ' and 11,11 '] have an annular or toric structure, are placed in the cylinder body [2] on the formed corresponding position.
