As rotary engines, for example Wankel engines are known. In these motors, a piston formed with a plurality of rounded surfaces is mounted in a cylinder whose inner wall is not circular, but has a plurality of concave recesses. The combustion chambers of this engine are in each case formed between the rounded surfaces of the piston and corresponding recesses of the cylinder. The disadvantage of the Wankel engine is mainly its complicated assembly, which requires a high production cost. Another problem is the sealing of the engine. Even very small leaks lead to a reduction in engine performance, an increase in the toxic components in the exhaust gases and increased fuel and oil consumption.

These are heat engines in which at least one piston reciprocally mounted in a cylinder moves through gases is whose temperature is cyclically changed by a heater, a heat storage device and a cooling device. A disadvantage of such engines are heat losses due to the cyclic temperature changes of the gases in connection with difficult to produce sealability of the gases, due to the prevailing in the engines high pressures. The life of such engines is also very limited due to high load and associated rapid wear of the engine components. The efficiency of most previously known Stirling engines is also limited by the efficiency of the regenerator in a physical way.

The object of the invention is to develop a based on the principle of the Stirling engine rotary piston Wärmemotor- device of the type mentioned so that an adaptation to a plurality of different operating conditions such as different temperature and pressure conditions in the cylinders is possible, so that the applications of the Device are extended.

The axis 6 of a piston 1 is formed as a solid rod 6, and the axis 7 of the other piston 2 is formed as a hollow rod, whose clear diameter is dimensioned so that the solid rod 6 is rotatably mounted in the hollow rod 7. The pistons 1, 2 each have boundary surfaces 10, 20, wherein between adjacent parts of opposing boundary surfaces 10, 20 are each predetermined equal distances. Between the respective Boundaries 10, 20, a plurality of effective displacement chambers 8, 9, 11, 12 is formed, which are bounded on the outside by the cylinder 3, and at the ends by the cylinder head 33 and the cover plate 30.

Furthermore, two pistons 1 ', 2' are rotatably mounted in a cylinder 3 'in the rotary piston heat engine device 100 shown in FIGS. 1 to 6, the axes of symmetry 14', 15 'of the piston 1', of the piston 2 '. and the cylinder 3 'are collinearly aligned.

Between the respective boundary surfaces 10 ', 20' is a plurality of effective displacement chambers 8 ', 9', 11 ', 12' is formed, which outwardly through the cylinder 3 ', and at the ends by the cylinder head 33' and the cover plate 30 ' are limited.

The two cylinders of the engine device according to the invention have differently dimensioned and differently arranged cylinder wall sections between the respective intake and exhaust ports. In a first cylinder of the engine according to the invention, a cylinder wall is provided between a first inlet slot of a Einlaßschlitzpaares and a first adjacent outlet slot of Auslaßschlitzpaares, which spans only a few angular degrees, and between the same inlet slot Einlaßschlitzpaares and another outlet slot of Auslaßschlitzpaares a cylinder wall provided, which spans about 60 degrees of angle.

The asymmetry between the inlet and outlet ports of the first cylinder and the second cylinder cause a timely transport of the working gas from one cylinder to another such that the engine is able to provide a working power.

A device 110 shown in Figure 2 causes in the rotary piston heat engine device 100 according to the invention that the oscillatory movement of the pistons 1 and 2, and the piston l'and 2 ', a circular motion is superimposed.

The device 110 has six oval gears 101, 102, 103, 104, 101 'and 104', whose major axes 111, 112, 113, 114, 111 'and 114' are arranged in pairs perpendicular to each other. In the device 110, the axis 7 of the other piston 2 is connected to a first oval gear 101, and the axis 6 of the one piston 1 is connected to a second oval gear 104, wherein these oval gears '' 101, 104 are arranged in collinear succession and the main axes 111, 114 of these oval gears 101, 104 are arranged perpendicular to each other. The first oval gear 101 and the second oval gear 104 are connected to each other via a third oval gear 102 and a fourth oval gear 103, wherein the gears 102 and 103 are arranged in collinear succession on a shaft 5, wherein the respective main axes 112, 113 the gears 102, 103 are arranged perpendicular to each other.

Furthermore, in the device 110, the axis 7 'of the other piston 2' is connected to a first oval gear 101 ', and the axis 6' of the one piston 1 'is connected to a second oval gear 104', these oval gears 101 ', 104 'are arranged collinear one behind the other and the main axes 111', 114 'of these oval gears 101', 104 'are arranged perpendicular to each other. The first oval gear 101 'and the second oval gear 104' are connected to each other via a third oval gear 102 and a fourth oval gear 103, wherein the gears 102 and 103 are arranged in collinear succession on a shaft 5, wherein the respective main axes 112 , 113 of the gears 102, 103 are arranged perpendicular to each other.

With such an arrangement, the gears 102 and 103, and the shafts 5 ', 5''of the two units (cylinder 3, and 3') operated. The above-described shaft 5 is shown in two separate temperature units, and therefore referred to in a first temperature unit as a shaft 5 'and in a second temperature unit as a shaft 5''. Such an arrangement applies for example to an assembly, as shown in Figures 3, 12 and 12a.

Another type of assembly is shown in Figures 11, 13 and 16 to 18b. Be Hirbei 8 as Ovalzahnräder ausgefürte non-circular gears (101, 102, 103, 104, 101 ', 102', 103 ', 104') on the shafts 5 'and 5 ", as well as a link (clutch, timing belt, chain o .). Linked together

The oval gears 101 to 104 and 101 'and 104' have a ratio of 1.7 / 1 with respect to the length of their longitudinal axes to that of their transverse axes.

During operation of the rotary piston heat engine device 100 according to the invention causes an expansion of a heated working gas, for example, in the displacement of the cylinder 3 3, a movement of the pistons 1, 2 in the direction away from each other. The connected to the axis 7 of the piston 2 oval gear 101 moves in the direction of that arrow, which is shown in Fig. 2 on its surface. In the starting position shown in Fig. 2 causes a rotation of the gear 104 by a small angular deflection a relatively large angular deflection of the arranged on the shaft 5 gear 103. The also arranged on the shaft 5 gear 102 transmits this movement to that with a further increase in the Angle deflection of the axis 7 of the piston 2 connected gear 101st

The different, changing local power transmission of the gears 101 rsp. 104 causes in that the oscillation movement of the pistons 1, 2 is superimposed by a circular movement. The working shaft 5 rotates at the average speed of the two pistons 1 and 2. At the extension of the working shaft 5 or 5 'or 5'', the rotational energy of the motor with constant angular velocity can be removed. At the extension of the shaft 6, the rotational energy of the motor is removable per revolution four times changing angular velocity, as is desirable for example for operating compressors.

The same applies to the unit of the cylinder 3 '.

Fig. 1 and la show an embodiment of the engine device according to the invention, in which two cylinders 3, 3 'with respective piston pairs 1, 2 or 1', 2 'via a corresponding pipe system 201, 201', 202, 202 ', 203, 203 'and 204, 204' via a heater 300, a radiator 400 and a regenerator or heat exchanger 200 are coupled together.

At the beginning of a working cycle, working gas heated by the heater 300 flows via the pipe system 202, 202 'into the inlet openings 130, 130' of the cylinder 3. The hot working gas subsequently flows into the intermediate space between the pistons 1, 2, whereby these pistons are forced apart. Thereby, the gap between the piston surfaces of the pistons 1, 2, which are located in the vicinity of the outlet openings 140, 140 'of the cylinder 3, compressed, so that the working gas located there through the pipe system 203, 203' escapes. About the pipe system 203, 203 ', the leaked from the cylinder 3 working gas via a heat exchanger 200, arrives it gives off its heat, via a cooler 400, where it is further cooled, in the pipe system 204, 204 'of the cylinder 3'.

From the pipe system 204, 204 'passes the now cooled working gas through the inlet openings 131, 131' of the cylinder 3 'in the vicinity of these inlet openings located between the piston 1' and 2'-, these piston interspaces are increased, and the Intermediate spaces adjoining the respective opposite piston surfaces of the pistons 1 ', 2' are reduced, so that the working gas located there is forced out of the cylinder 3 'into the pipe system 201, 201' via the outlet openings 141, 141 '. Via the pipe system 201, 201 ', this working gas continues to flow through the regenerator or heat exchanger 200, where it absorbs heat from the working gas which flows from the pipe system 203, 203' through the heat exchanger 200.

After exiting the heat exchanger 200, the now heated working gas originating from the pipe system 201, 201 'continues to flow through a heater 300, in which it is further heated. From there it flows into the pipe system 202, 202 ', from where the cycle repeats itself.

In the Stirling engine according to the invention shown in FIGS. 4 and 4a, two cylinders 3, 3 'are coupled to one another via a corresponding pipe system via two heaters 300 or 300', two regenerators or heat exchangers 200, 200 'and two coolers 400 or 400' ,

At the beginning of a rotation cycle of this engine, working gas heated by the respective heaters 300, 300 'flows via the respective tubes 202, 202 'in the inlet openings 130, 130' of the cylinder 3. About the inlet ports 130, 130 'enters the hot working gas in the underlying spaces between the pistons 1, 2, and pushes these pistons apart. As a result, the spaces between the pistons 1, 2 formed by the respective opposite piston surfaces 10, 20 are compressed, and the working gas located there is via the outlet openings 140, 140 'in the respective. Tubes 203, 203 'pressed.

The working gas forced into the pipe 203 passes in sequence through the regenerator 200 and the radiator 400 into the pipe 204 which opens into the inlet port 131 of the cylinder 3 ', and the working gas forced into the pipe 203' passes through the regenerator 200 'and the radiator 400 'in the tube 204', which opens into the inlet opening 131 '. The entering into the inlet port 131 of the cylinder 3 'working gas has thus given off a portion of its heat to the regenerator 200 and is then further cooled by the radiator 400, so that it is present at the inlet port 131 with respect to the tube 203 greatly lowered temperature.

The applied at the inlet port 131 'working gas has given a large part of its heat to the regenerator 200' and is then further cooled by the radiator 400 'so that it at the inlet port 131' of the cylinder 3 'opposite the tube 203' in strong cooled form is present. Through the inlet ports 131, 131 'of the cylinder 3' thus enters cold working gas in the located below these inlet openings spaces between the piston 1 'and 2', wherein the spaces between This piston can be increased and the respectively by the opposite piston surfaces 10 ', 20' of the piston 1 ', 2' formed intermediate spaces, which are located below the outlet openings 141, 141 'of the cylinder 3', be reduced. By compressing these piston interstices, the working gases therein are forced through the outlet ports 141, 141 'into the tube 201 and into the tube 201', respectively. The working gas in the tube 201 is first preheated by the regenerator 200 and then heated by the heater 300, from where it enters the tube 202. The working gas in the pipe 201 'is preheated by the regenerator 200' and then heated by the heater 300 'from where it enters the pipe 202'. As a result, the cycle described above is repeated.

The operating sequence takes place identically in the case of the motor devices according to the invention as shown in FIGS. 1 and 1 a and FIGS. 4 and 4 a. In principle, the working gas in the pipe system and the cylinders passes through four changes of state which are predetermined by corresponding working cycles of the pistons of the cylinders 3, 3 '.

In a first working cycle of the engine according to the invention, working gas is compressed in the respective interspaces between the pistons 1, 2, 1 ', 2' of the cylinders 3, 3 'by a movement of the respective pistons towards one another.

In a second cycle of the engine according to the invention, the thus heated working gas, via the outlet opening 141 of the cylinder 3 'has been pressed into the tube 201 or via the outlet opening 141' of the cylinder 3 'in the tube 201' further heated by the regenerators 200 'and 200 and the heaters 300' and 300, respectively in the working gas prevailing pressure is further increased. In the tube 202 behind the heater 300 and in the tube 202 'behind the heater 300', therefore, there is a total of maximum pressure of the working gas in the entire pipe system.

Through the inlet ports 130, 130 'therefore occurs under high pressure working gas in the cylinder 3 and passes between corresponding spaces between the pistons 1, 2 and pushes these pistons apart at high pressure. This corresponds to a third cycle of the engine according to the invention. The heat energy of the working gas is converted in this working cycle of the engine according to the invention by a pushing apart of the spaces between the pistons 1, 2 of the cylinder 3 in rotational energy of these pistons. The working gas cools down in a third state change.

In a fourth cycle of operation of the engine according to the invention, the working gas thus relaxed is forced out of the cylinder 3 via the outlet ports 140, 140 'by compressing the respective spaces between the pistons 1, 2 due to expansion of the spaces between these pistons in the direction of rotation of the engine , The working gas then undergoes a fourth state change by being further cooled by the regenerators 200 and 200 'and the coolers 400 and 400', so that it is in a highly cooled state in the tubes 204 and 204 '. With the time of entry into the inlet openings 204 'and 204 and after entering the inlet openings 204' and 204, the working gas is compressed again.

The state of the working gas, defined by its pressure and its temperature, is summarized summarized in Table 1 summary.
