The compression chamber is in gas connection with at least one ignition chamber (7), and the same is in gas connection with at least one expansion chamber c*. This chamber is formed by the housing (10/10') and an expansion rotary piston (2) rotating therein on a shaft. At least one flywheel (3) rotating in the housing (10/10') on a shaft provided for the power intake forms a compression chamber b* together with the compressor rotary piston (1), and an expansion chamber c* together with the expansion rotary piston (2). The ignition chamber (7) is equipped with a device for igniting a compressed gas mixture.

Description

COMBUSTION ENGINE

The invention relates to an internal combustion engine on the basis of 'rotary piston', or on the basis of certain designed, rotating on an axis functionally mutually corresponding disc-shaped components for compression of combustion gases and expansion of combusted gases.

In such engines, clean compression is the linchpin between combustion and force-providing expansion. Since rotary piston engines have much higher speeds than, for example, the Otto engines with piston-conrod crankshaft, but have the same firing order or work cycles, and because the compression volume is much smaller than in piston engines (by a factor of 10 to 20), these are Engines, so to speak, more sensitive, as far as the timing of the steps sucking, compression, ignition and expansion is concerned.

The realization of short to extremely short gas paths, that is, short conductions between the power stroke units is an important requirement. The compression must be virtually lossless run in an extremely short time, including a special design of the gas-compressing unit, so the compressor is necessary. For expansion with short gas paths, the design and design of the ignition chamber must meet the requirement of short time and the arrangement of the elements for the power strokes, namely suction, compression, ignition and expansion must be adapted to these requirements. An engine of this type in various embodiments is the subject of the invention, the features of which are defined in the claims.

A problem for the transmission of these requirements lies in the complete avoidance of the design of the usual rotary piston engines. For some embodiments, there is no reference to existing designs.

A first embodiment of the rotary piston engine according to the invention has two working rotary pistons which operate on a common flywheel. The flywheel has different functions; it is an inertia buffer and energy store to the gear train, it is also a sealing member to the compression and expansion chambers and it is a shut-off associated with the seal of the working rotary pistons. These are the compressor rotary piston and the expansion rotary piston. The working rotary pistons and the flywheel are positively synchronized via a toothing. This engine operates twice per revolution of the flywheel, the classic work cycles of the gasoline engine from suction-compression-ignition-expanding.

A further embodiment is a motor according to the invention, which has two further working rotary pistons (compressor rotary pistons and expansion rotary pistons) operating on the same one flywheel for the embodiment described above. Thus, the cycles of the power strokes, suction-compression-ignition-expanding are doubled, that is, the engine operates four times the classic work cycles per revolution of the flywheel or per revolution of the drive shaft to the transmission. Another embodiment of the engine involves a reduction in the number of work cycles per revolution by the working rotary pistons (compression and expansion) each act on its own flywheel, the same degree of compression is required, but can be due to the reduced number of work cycles per revolution of the drive shaft of this engine to substantially higher speeds are brought.

A further embodiment, a variant of the latter engine operates with an additional intake, formed from a working rotary piston and a flywheel for pre-compression at very high speeds.

In the following discussion the principle of the new and innovative rotary piston engine is presented. Above all, the essential elements and their function are discussed. Some parts are shown only schematically, such as the electric ignition device. Not shown are devices for cooling (in principle, a jacket for the circulation of a coolant), also not shown, the carburetor or injector (in principle, a commercial device) and also not shown are any exhaust gas ducts unless they concern the immediate engine activity.

Figure 1 shows an embodiment of the invention in an arrangement with 3 axes or shafts. The motor is shown to show the details without housing. However, the housing is not simply an enclosure, but a functional part of the engine with gas ducts and sealing functions and chambers forming parts, which is still shown in other figures or sectional drawings with the housing. Compared to Figure 2A, the motor is tilted so as to look from 'up'; in FIG. 2A this is more of 'below' to show specific details in each case.

The engine essentially comprises three working parts, a compressor rotary piston 1, an expansion rotary piston 2 and a cooperating with two rotary piston flywheel 3. The two working rotary pistons 1 and 2 have iml80 (angle) degree opposite each other two sealing strips 11 and 21 on. The flywheel has 180 degrees opposite to each other two correspondingly shaped recesses 31, in which the seals dip in turns and can roll off. Between the sealing strips and the (not shown in this figure) housing chambers are formed, which are provided by the movement of the sealing strip variable, in the direction of rotation to reduce compression and enlarging for the expansion. More below.

Seen from the front, the two working rotary pistons 1 and 2 rotate clockwise, the flywheel 3 revolves counterclockwise. This is indicated by arrows. The position of the facing sealing strips 11 and 21 in FIG. 1 shows the approximate end of the compression of the compressor rotary piston 1 shortly before ignition and the immediately commencing expansion of the expansion rotary piston 2 after ignition in the ignition chamber 7, the latter being connected to the chambers for compression and expansion through inlets and outlets in the housing is. In the 'back' part of the figure can be seen the teeth 12 for forced synchronization of the rotary piston and the flywheel. When the engine is running, the force is removed from the shaft 18 on the flywheel 3. Shown is also a flange 15, on which the fuel supply (eg carburetor) is placed. The flange 15 for the carburetor and the flanges 24 for the working elements are mounted on a base plate 10 ', not shown in this figure, it forms part of the housing. The mating flanges 24 'for supporting the shafts are fixed to the housing 10. The central bore in the flange 15 for the carburetor leads directly into the compression chamber, which can not be shown because of the housing, not shown in this figure. So much for the general working principle. With the number 14, a cover of the formed in the housing ignition chamber is shown, which also serves as a seat for the just visible spark plug 13 here. Furthermore, it can be seen on the sealing strips 11 of the compression part so-called Kippleistendichtungen 4 and between the working rotary piston 1 and 2, a so-called pendulum seal 5 with a receptacle 9 for a pressure device.

Figure 2A shows the same motor tilted slightly backwards to discuss a few details, which are shown enlarged within the drawn circle representing Figure 2B. By tilting the engine now visible, is a schematically illustrated electrical ignition device 16 on the gear side, with which the spark plug is electrically connected. The pendulum seal 5 is now visible obliquely from below. The details in Figure 2B are as follows: an extremely good seal between the housing and the high-speed rotating compressor rotary piston 1 and also between the transition of the interaction of dipping and rolling sealing strips 11 and 21 in one of the two recesses 31 of the flywheel 3, Two major measures are foreseen. On the sealing strips 11 of the compressor rotary piston 1 tilting strip seals 4 are arranged pivotable about a longitudinal axis and in the housing part, not shown, the pendulum seal 5 is also movably arranged, which is slightly displaceable about its longitudinal axis, represented by a double arrow, between the housing and flywheel 3 is arranged. In FIG. 2B, it can be seen how the recess 31 of the flywheel 3 begins to pass under the pendulum seal 5. The sealing strip 11 of the compressor rotary piston 1 with the tilting strip seal 4 is ready to dive into the oncoming recess 31. The viewed in the direction of rotation, front side of the recess 31, was just involved in the compression and precisely sealed on the one hand by the Kippleistendichtung 4 against the housing and by the pendulum seal 5 against the flywheel 3. Laterally, so the front side between the housing and the compressor rotary piston is / are one or two ring seal / en example. Made of bronze for adequate sealing provided. The sealing of the precisely fitted flywheel against the housing takes place via an oil film.

The tilting pad seal 4, which, because it is movable, conforms smoothly to the chamber surface in the housing is shown in detail in FIG. 2D. For a better illustration of the engine in Figure 2C is reversed (gears 12 forward, previously backwards) and drawn with a circle of the cutout for Figure 2D. The tilting strip seal 4 placed on the compression sealing strip 11 is pivotably mounted about an axis so that it can be lifted off its seat, as indicated by an arrow. Two, arranged in this example, small axial stops on the left and right to prevent possibly too strong tilting when passing Through the recess 31 of the flywheel 3. At the base of the compression sealing strip 11 can be seen three approximately radial holes 28, the Verdichterbonrungen (see also Figure 3C). Through this, the compressed ignition mixture is led to a common transverse bore, the transfer hole 29 and introduced from there via a bore in the housing directly into the ignition chamber 7. This for one sealing strip per compressor rotary piston.

In Figures 1 and 3A and 3B can be seen Aufhahmeöffhung or bore 9 on the pendulum seal 5 for an eccentrically acting on the pendulum seal 5 adjustment mechanism (not shown in these figures, but in principle bolt / coil spring / screw), via which, for example. Press a bolt elastically onto the pendulum seal via a coil spring. On an adjusting screw, the pressure of the pendulum seal is adjusted to the running surface of the flywheel. This adjustment is not shown. Further details will be discussed below.

For further overview serve the two figures 3A and 3B and 3C. Figure 3A is a top view of the engine, Figure 3B is an enlarged detail thereof, and Figure 3C is a sectional view of the rotary members. It can be seen in the detail image 3B, a spark plug 13, which protrudes with its electrodes 13 * in the ignition chamber 7, formed in the housing. To cover the ignition chamber 7 is a cover plate 14, which serves as a holder for the spark plug 13 at the same time. All other essential parts, such as the highly visible pendulum seal 5, have already been discussed. The ignition chamber 7 is located in the housing, in which the compressed ignition mixture via a bore in the housing (shown above) fed from the compression chamber and the exploding gas is discharged through a further bore in the housing in the expansion chamber. This is shown in detail in section according to FIG. 3C. One recognizes the gas inlet gas shown in FIG. 2D. make holes 28 on the compression strip and the transverse thereto gas transfer hole 29th

Here an example of the configuration of the ignition chamber: it has in the discussed embodiment a height / width of 10x10 mm and a length of 60 mm, which corresponds to a volume of 6 cm3. It is milled into the housing with a milling cutter. The inlet hole into the ignition chamber has a diameter of 6mm and the outlet hole in the expansion chamber also has a diameter of 6mm. Both holes are inserted in the housing. At a compression of 10 bar, a gas quantity of the ignition mixture of about 60 cm3 is sucked in and compressed into the ignition chamber. After combustion and expansion, this corresponds to a gas volume of about 240 cm3. In the region of the inlet bore a check valve is arranged or in a recess in the ignition chamber above the input bore a one-way flap valve, both not shown, whereby at the ignition of the mixture, the expanding gas at the moment of the aligned gas passages not into the space of the housing and rotary piston and can cross into the compression chamber there. Housing 10 and rotary piston 1 are also sealed with, for example, one or two ring seals 8. These are precautions to achieve maximum compaction.

Figures 4A and 4B and 4C now show the motor in the housing. This consists of the housing 10 and the base plate 10 ', whereby now the internal components are covered and no longer visible, as was the case in the preceding figures. Figure 4A shows the engine from the side; two sections, one vertical and one horizontal, Figures 4B and 4D. FIG. 4C shows a detail from the section of FIG. 4B. Due to the presence of the housing, the annular chambers 19 for compression and for expansion 20 and for suction 17 are now visible. The chambers are further explained below with a, b, b * and c, c * d, to explain the function, the chambers b and b * being divided by a barrier S 1 and the chambers c and c * by a barrier S2 , Furthermore, it can be seen how the pendulum seal 5 is arranged in the housing 10. It is so large that it can still be found just in the case to show details, but it is usually a little smaller in diameter. The pendulum seal is in the embodiment shown by the housing so far encompassed that it is quasi on a Oelfihn, floating 'about its longitudinal axis movable, so no axis to support needs. Figure 4B also shows a significant point in the arrangement of the axes or shafts to each other. The included angle between the axis of the flywheel 3 with the axes of the two working rotary pistons 1 and 2 is less than 90 degrees here, advantageously an angle between 70-80 degrees, for example, has proven to be 75 degrees. This angle determines the distance of the inlet and outlet holes to and from the ignition chamber. This distance should be short, but this determines the size / length of the ignition chamber. The angle also determines the flow of the sealing strip of the working rotary piston.

Figure 4C shows a section of the previously discussed function of the pendulum seal 5. It can be seen how it is arranged in the housing 10, namely rotatably. The directions of rotation of the working rotary piston and flywheel are as already shown above, the flywheel recess 31 passes under the pendulum seal to receive the compression seal strip 11 with the tilting strip seal 4. In the hole 9 for the pressure device 6, an arrow is shown, which is to show the pressure device 6, bolt-spring-screw on the pendulum seal 5 and how to turn the pendulum seal or can press on the flywheel. This of course only adds a tiny sealing angle to the flywheel so that the oil film does not get damaged or damaged is demolished. At the compressor rotary piston can be seen the compressor bore 28 with the transfer hole 29 through which the compressed ignition mixture is transferred into the ignition chamber. Furthermore, here are shown two locks Sl and S2 between the working rotary piston and the flywheel, which divides the lower chambers, b and c into chambers b / b * and c / c *. More below.

Figure 4D shows the horizontal section of Figure 4A. The section runs just above the spark plug 13, so that a part of the ignition chamber 7 is visible. It can be seen how the base plate 10 'with the bearing flanges 24' and the housing 10 with the bearing flanges 24 store the bearing for the shafts of the working rotary pistons 1 and 2 and the shaft of the flywheel 3. Furthermore, one sees in section through the compressor rotary piston 1, the sealing grooves 8 for the frontal seals between the piston and the housing, for example, made of bronze. You can also see the chambers 19 for compression and 20 for expansion. The bearing of the expansion rotary piston 2 is visible in this section, for the compression rotary piston, the cut passes under the storage.

Figures 5 A and 5B show the engine with housing 10 and cover plate 10 'from the side with a flange 15 for a carburetor and from the other side with the teeth 12 for the forced synchronization and the ignition device 16 shown only schematically between the gears 12th you can still see the seat for the spark plug 13. This, so that you can see the external shape of the engine of this embodiment.

FIGS. 6A and 6B show, similar to FIGS. 5A and 5B, an embodiment in the housing, but with five axes or shafts, in other words, an embodiment with four working rotary pistons which are based on the same momentum. Disc work. It can be seen in Figure 6 A, the housing 10 with base plate 10 ', the flanges for the axle bearings 24', and a second flange 15 'for the connection of a second carburetor. Further added are behind the toothing in the housing (FIG. 6B), synchronized with the same flywheel 3, below another compressor rotary piston 1 ', another expansion rotary piston 2' (of course behind the gear in the housing), a further ignition chamber 7 ', another spark plug 13 ', in short, a quasi doubling of the engine. Without housing, Figure 7A shows. This results in ignitions instead of 2 as in the first embodiment shown above 4 ignitions per revolution, in other words four times the possible power output of the engine. This to the overview of the second embodiment.

Figure 7 A shows, virtually around the flywheel 3 each arranged a compressor rotary piston 1 and 1 ', each an expansion rotary piston 2 and 2', and for each unit of work a flange 15 and 15 'for two carburetors. All other components have been discussed essentially with the aid of the preceding figures. In the drawn circle, a detail is taken out for the figure 7B, which would have overloaded the drawing in Figure 1.

FIG. 7B thus shows a section of FIG. 7A. FIG. 7C shows the motor without housing from the side and FIG. 7D shows a section through FIG. 7C. The essential details in FIG. 7C are the gearwheels 12 of the synchronization toothing, the working rotary pistons, the flywheel disk 3 with its axle / shaft 32, to which the shaft 18 adjoins for power take-off. The two carburetor flanges 14 are visible on the left side. FIG. 7E shows a section with details from the section (without housing) according to FIG. 7D. The cut is such that it is directed through the lack of housing not visible ignition chamber through to the contacts 13 * of the spark plug 13, which is screwed into the holding plate 14. On the Side of the added two working units 1 'and 2' (in Fig. 7D below), the pendulum seal 5 is omitted to have the view of the contacts of the spark plug 13 'and their contact 13 * freely visible. On the compressor rotary piston 1 and 1 'you can see the holes 29 for the transition of the compressed Zündgemisches in the ignition 7. In detail, this also shows Figure 7E in the up to now discussed position of the working rotary piston at the end of the compression in the chamber b *, shortly before the explosion or shortly before the expansion in the chamber c *. Of course, apply to the added working rotary piston the same specifications with respect to the geometries between the axes and the flywheel 3 as in the first embodiment, namely an angle less than 90 degrees.

FIG. 8A shows the motor from the side and a section according to FIG. 8B through the motor in the housing 10 without the base plate 10 'in such a way that it intersects the working rotary pistons 1, 2, 1', 2 'and the exhaust ducts 33 and 34 , The arrows in FIG. 8B indicate the directions of rotation of the four working rotary pistons and the flywheel. One recognizes again the positions of the compression sealing strip 11 or expansion sealing strip 21 at the end of the compression and the beginning of the expansion. The two 180 degrees opposite sealing bar of each working rotary piston form two chambers for each of the working rotary piston, here a and b / b * to the compressor rotary piston 1 and 1 'and two chambers c / c * and d to the expansion rotary piston 2 and 2'. The working rotary pistons rotate clockwise (in this illustration) and the flywheel counterclockwise.

The chambers b * and b are bisected by the contact of the expansion rotating pistons with the flywheel, into a small b * and into a larger part b. The contact point causes a sealed by an oil film lock Sl between the two parts. The chambers c * and c are also divided into two parts by the contact of the expansion rotating pistons with the flywheel small c * and in a larger part c. The point of contact causes a barrier S2 between the two parts. The teilkreisringförmigen chambers have in this embodiment approximately a volume of 80 cm3. During the revolution, this volume in the ignition chamber is compressed to approx. 10 cm3. Per revolution twice and. At 10 ¹ OOO rpm rotary engines, these are not very fast-revving engines, but at the stated speed suction-Verdichten- ignition-expansion occurs around 167 times per second for two gasoline engine ignition sequences in other words, depending on a firing order within about 3 milliseconds.

In the chambers a begins (if you start to rotate after the successful ignition of the gas mixture 2xι), the compression, the chambers b begin to suck. The chambers c * undergoes expansion, and from the chambers d and c the burnt ignition mixture is expelled through the exhaust ducts 33 and 34. The chambers c * and c are bisected by the contact of the expansion rotating pistons with the flywheel, into a small c * and into a larger part c. The contact point causes, as I said, a barrier between the two parts. The smaller part c * is connected to the outlet hole of the ignition chamber and is exposed to the expansion pressure. The larger chamber c still contains relaxed combustion gas, which would be compressed at the barrier. To prevent this, the outlet 33 is provided. It should be noted that the name of the chambers is only a temporary one, as in a snapshot.

The position of the rotary pistons show the approximate time of ignition and expansion. The sealing strip 11 with the tilting strip seal 4 on the compressor rotary piston 1 and 1 'has pressed the compressed ignition mixture through an example. Disposable flutter valve (not shown) into the ignition chamber and now immersed in the recess 31 in the flywheel 3 a. The one-way flap valve consists, for example, of a spring arranged over the inlet opening in the ignition chamber. the steel sheet, for example, as used in 2-stroke engines. The expansion sealing strip 21 on the expansion rotary pistons 2 and 2 'have now just emerged from the recess in the flywheel and are ready to be driven upwards (or downwards) by the expansion by the exploded ignition mixture. The chamber above the sealing strip begins to emit burned gas through the short exhaust passage 33, as well in the chamber c under the second sealing strip, where the expanded smoke is expelled through the long exhaust passage 34. The two small chambers b * at the end of the compression and the beginning of the expansion c * must be extremely well sealed against each other, so that the compressed gas (in this case through the paper plane) is pressed into the ignition chamber and after ignition does not overlap the expansion in the compression chamber , Serves the pendulum seal 5, which is pressed by the example shown in Figure 4C adjusting device 6 adequately on the flywheel. The Kippleistendichtung 4 ensures maximum compression, the pendulum seal 5 prevents penetration between the compression and expansion part. On the expansion side, such a measure is not necessary because the expansion losses in the rapidly increasing volume are not significant. In contrast, a volume loss at the relatively low volume in the compression part is significant.

Figure 8C shows the engine from the side with a section showing once in the direction D to the carburetor flange and once in the direction F for the synchronization toothing. Corresponding to the reversal of the viewing direction, of course, there is a reversal of the direction of rotation of the working rotary pistons. FIG. 8D and detail FIG. 8E show details in the direction of the carburetor flange, and FIG. 8F and detail FIG. 8G show details in the direction of the synchronization toothing. FIG. 8C shows, on the one side, the two carburetor flanges 15 and the shaft 18 for power take-off on the flywheel, and on the other side one can see the synchronization toothing 12 and the electrical ignition device 16. Figures 8D and 8E show the compression chambers of the compressor rotary pistons 1 and 1 'show in the vicinity of the locking point Sl with the flywheel 3, the inlet bore 15 * of the ignition mixture from the carburetor for compression in the one chamber, which now sucks behind the barrier S 1 (the Sealing strip 11, 11 'with the Kippleistendichtungen 4, 4' rotate counterclockwise). The other, opposite chamber has received the mixture for compression and begins to compress. As soon as the sealing strips 11, 11 'in the vicinity of the flywheel recess 31 dips into it and turns away, the compression on the one hand and the suction from the carburetor on the other hand begins.

Figures 8F and 8G show in the same sectional plane against the toothing. FIG. 8F shows, in particular, the locks S1, S2, S1 'and S2' from the flywheel to the working rotary pistons for forming the compression and expansion chambers. It should be noted here that this design of a motor in this form alone is completely new. Since now the expansion (which is the explosion of the ignition mixture) provides a much larger amount of gas than the compressed volume (40-50 times more) and this larger amount of gas must be routed as quickly as possible in the exhaust chamber, the expansion rotary piston 2, with the concession of minimal expansion pressure loss, for example additional outlet grooves 22, which somewhat increase the initial expansion volume c * to the later exhaust gas chamber. These Austrittnuten 22 are, as attached to previously discussed figures only on the side of the expansion Rotationskolben and cause at the barrier S2 between the small c * and the larger chamber c a certain, but negligible expansion pressure loss towards larger chamber. It can also be seen well in FIG. 8G at the left upper edge how the expansion sealing strip 21 has emerged from the flywheel recess 3 and the recess now passes under the pendulum seal 5. In order to illustrate the motor housing alone, FIGS. 9A and 9E, 9F, 9G and 9G are still for engine parts, FIGS. 9B, 9C and 9D are for the rear side. Thus, FIG. 9A shows the five rotation elements in the housing 10 without the base plate 10 'embedded. Again, the components have been omitted, which have already been discussed and do not contribute to the explanation. Clockwise at the top left you can see the first compressor rotary piston 1 and right above the first expansion rotary piston 2. Bottom right you can see the second compressor rotary piston 1 'and bottom left finally the second expansion rotary piston 2'. All four working rotary pistons act on the centrally located flywheel3. Well visible here are the discussed chambers, which are finally completed by the base plate 10 'to the tight chamber. Furthermore, it can be seen at the position of the intake chambers b and b 'of the compressor rotary pistons 1 and 1', the carburetor flanges 15 and 15 'Finally, you can still see the outside of the housing, the output of the short 33 and 34 long exhaust channels.

FIG. 9B now shows the 'empty' housing. On the inside, the holes E for the inlet to and A for the outlet to and from the ignition chamber are partially hidden. As well as the holes for the discharge of the burned gases, which are shown in Figure 9C and 9D in section. These holes do not lead directly into the respective chambers, they are connected via holes in the compressor rotary piston, the Uberleitungsbohrung 29 and the compressor bore 28, connected to the chambers. FIG. 9E shows the two slit-shaped, cranked (stepped) recesses arranged on the rear side of the housing, the smaller one for the ignition chamber 7 and the larger one 14 'for the cover 14 of the ignition chamber 7, which at the same time serves as a holder 14 for the spark plug 13 , This has already been shown on earlier figures. In FIG. 9F, the exit bore A of the expansion chamber c * from the ignition chamber 7 can be seen on the rear side of the ignition chamber, which is shown in FIG Section according to Figure 9G is clearly visible. In this figure can be seen above the ignition chamber 7 with the recess for the cover plate 14 and the output hole A to the expansion chamber and below you can see only the ignition chamber 7 with the cover plate 14 because of the slightly obliquely guided cut on the input hole E over. Of course, the ignition chamber is very small compared to the size of the engine. FIG. 9D, a section in the plane of the exhaust ducts of FIG. 9C, shows these and the inputs for the ignition mixture and outlets for the combustion gases to and from the ignition chambers and the recesses for the pendulum seals 5, if these are used in the first two embodiments. be.

A further embodiment is shown in FIGS. 10A, 10B and 10C. Figure 10A shows an isometric view of the motor without housing. From front to back can be seen the compressor rotary piston 1 with the compression strips 11 and arranged thereon Kippleistendungen 4, including a first flywheel 3 with the recesses 31 and the (arranged in the housing) pendulum seal 5 with the recess or bore 9 for the bolt already discussed Pressure device 6. The flange 15 for the carburetor sits on the housing, not shown here, via a bore which leads into the compression chamber b *, shown in a later figure. Behind the distance of the housing can be seen the expansion rotary piston 2 with the exit grooves 22 and cooperating with him second flywheel 3. Behind it recognizes the gears 12 for the synchronization teeth and in the axis line of the flywheels can still see a part of the electrical ignition device 16 shown schematically. The working principle in this embodiment is substantially the same as described above. This embodiment will be shown again below with reference to sectional figures. Figures 1OB and IOC show the engine in front and in rear view. One can see in these two figures the position of the spark plug 13 and, above all, the position of the pendulum seal 5 arranged in the housing. An arrow pointing past the center of rotation of the pendulum seal on the pendulum seal represents how this seal by means of the pressure device 6 depending on the voltage the coil spring (light) is pressed against the flywheel. In both figures can be seen here a 90 degree lead to the strips 11 and 21 of a working rotary piston 1 to the other working rotary piston 2 (looks like a cross). In contrast, the previous embodiments have a lead angle of less than 90 degrees (75 degrees in the example). Furthermore, it can be seen on the compressor rotary piston 1 grooves for a ring seal for sealing on the housing part, which is not shown here. In the background you can see the synchronization teeth with the gears 12. The ignition chamber 7 is incorporated in the housing between the two working rotary pistons 1 and 2.

Another embodiment is shown in FIGS. 1A and 1B. FIG. 11A shows an isometric view of the motor without a housing, but illustrating the housing periphery with the flange screws 25 holding the housing parts. The working rotary pistons have an associated flywheel, as in the previously described embodiment, and this embodiment also has an additional working rotary piston 35 for sucking the combustion mixture, which also cooperates with its own (third) flywheel. The flow of the sealing strips 11 and 21 of the compressor and expansion rotary pistons 1 and 2 is the same 90 degrees, during which the sealing strip of the Ansaugrotationskolbens 35 to the sealing strips 11 of the compressor rotary piston 1 have no flow. With this additional stage of work, some precompression can be achieved to increase the compression effect in the compressor calls. For high-speed engines, this has an additional effect on overall compression. In principle, a sol- suction stage are also arranged on all embodiments discussed above.

Figure IB shows a view from above into the engine. The pair of compacting pistons 1 and expansion rotary pistons 2 can be seen with the ignition chamber in between, which can not be represented without the housing (in the first three embodiments, the ignition chamber lies laterally of the working rotary pistons). However, one recognizes their position on the position of the spark plug contacts. The details on and between the two working rotary pistons in the housing show the following figures.

Figures 12A, 12B, 12C, 12D and 12E show various sections through the two last embodiments, that is, through the compressor part with the compressor rotary piston 1 and through the expansion part with the expansion rotary piston 2 and through the ignition chamber 7. Figure 12A shows the engine of the side and showing the location of the three sections A, F and E. Section D refers to Figure 12D. From this figure, a section is still shown in Figure 12E.

FIG. 12B shows the section through the expansion rotary piston 2 such that the outlets for the burnt exhaust gas are visible in the housing. Since the expansion (that is the explosion) provides a much larger amount of gas than the compressed volume and this larger amount of gas must be routed into the exhaust chamber as quickly as possible, the expansion rotary piston has the additional outlet grooves 22 (previous figure) which the volume of the exhaust chamber greater. The blocking point S2 between the expansion rotary piston 2 and the flywheel 3 separates the expansion chamber 20 into the larger chamber c and the smaller chamber c *, which is also to be regarded only as a snapshot. On the right side is still a part of the spark plug 13 visible. FIG. 12C shows the section through the housing in a plane which intersects the ignition chamber, that is to say between the compressor rotary piston 1 and the expansion rotary piston 2. In addition to the candle 13 in section, the inlet bore 30 for the ignition mixture is identified in the ignition chamber 7, which is closed by, for example, a check valve or a disposable flutter valve (not shown) against the compression chamber. If one draws a line from the outlet bore in FIG. 12C to the inlet bore in FIG. 12D, it can be seen that these two bore parts lie on a line and correspond exactly. Not shown is the exit bore from the ignition chamber to the expansion chamber, which leads into the smaller expansion chamber c *.

Figure 12 D shows the section through the compressor rotary piston 1 in a plane so that the bore for the pressure device 6 to the pendulum seal 5 is visible. Also visible is the compressor bore 28 in the compressor rotary piston 1 and the Uberleitungsbohrung 29 in the housing, through which the compressed, to be ignited gas mixture is passed into the ignition chamber. These details are more visible in Figure 12E. Again, it can be seen how the one compression chamber 19 is divided by the blocking point Sl between the compressor rotary piston 1 and the flywheel 3 in a smaller chamber b * and a larger chamber b. Figure 12E shows the situation discussed several times above at the end of compaction. During the compression phase, the ignition mixture has been forced out of the compression chamber b * through the compression bores 28 (in the example, three of them) in the compressor rotary piston 1 into the transfer bore 29 to the ignition chamber. Furthermore, you can see the hole 9 for receiving the pressure device 6 to the rotatable pendulum seal 5, which presses this decentralized and sealing on flywheel. The loss-free as possible compression of the compression is arranged by the arranged on the sealing strips 1 1 Kippleisten- 4 seals and ensured by the pressed onto the flywheel pendulum seal 5.

In summary, an internal combustion engine according to the invention comprises at least one compression chamber a, b / b * formed by a housing 10/10 'and rotating therein on a rotary compressor rotary piston 1,1' on Kompressionsdichtungs- perform 11 arranged movable tilting strip seals 4 in the gas network with at least one ignition chamber 7 and via these in gas connection standing at least one expansion chamber formed by the housing 10,10 'and therein on a shaft rotating expansion rotary piston 2,2' with expansion sealing afford, wherein a housing in the housing 10,10 'on a provided for the power take-off shaft 18th rotating at least one flywheel 3 with recesses 31 for receiving the compression sealing strips and expansion sealing strips 11,21 of the rotary piston together with the compressor rotary piston 1,1 'a compression chamber a, b, b * and with the expansion rotary piston 2,2' an expansion chamber d, c c * forms and in the housing part 1 0 is arranged a pendulum seal 5 with contact with the flywheel, and the ignition chamber 7 is provided with a device for ignition 13, 13 *, 16 of a compressed via the compression chamber in the ignition chamber gas mixture.

The new design of the internal combustion engine consists of a compression chamber a, b / b * formed by a housing 10/10 'and rotating on a first shaft compressor rotary piston 1,1' with compression sealing strips 11 in the gas network with at least one ignition chamber 7 and via this in gas connection standing expansion chamber d, c, c * formed by the housing 10,10 'and therein on a second shaft rotating expansion rotary piston 2 with expansion sealing strips 21, wherein in the housing 10,10' on a provided for the power receiving third shaft 18 rotating flywheel 3 with Recesses 31 for the Including the sealing strips 11,21 of the rotary piston together with the compressor rotary piston 1 via a first lock Sl compression chambers a, b, b * and with the expansion rotary piston 2 via a second lock S2 expansion chambers d, c, c * form and the ignition chamber 7 with a device for the ignition 13, 13 *, 16 of a compressed via the compression chamber in the ignition chamber gas mixture is provided, wherein the working rotary pistons 1 and 2 and the flywheel 3 each have their own axis / shaft 26, 27 and 32.

This new arrangement can still be associated with a working rotary piston pair each with its own axis / shaft, which operates on the same flywheel.

It is in the new design of the engine, no matter what version, immediately visible that this engine is essentially running on oil films and the current Oelzugabe is minimal (drop by drop), since it is built so that the oil film also has a sealing effect and therefore extremely is thin. It is therefore not comparable to the usual construction, in particular as regards piston engines, although the intake compression ignition expansion sequence is the same.
