E02853/00, 2000) (2). In this engine, the pistons are removed from the cylindrical rotor in the form of disks with a nanny in the form of blades and installed with the possibility of slots, in which, with the possibility of movement, rotation in the cylinder around the locking fingers, shaped profile inserts with working cylinders are fixed in the rotor disks. The guide fingers are two-way pistons placed in the cylinders passed through the arc-shaped slots of the rotor discs, which have fingers installed with the possibility of reciprocating interaction with the guide grooves. The answer is in them. According to the invention, the gap between the inner surfaces of the side covers are made of metal rotor covers, the edges of the cavities that form a ceramic material, the slots in the rotor disks are covered by the sealing surfaces of the cylinders and are oriented radially and have rotations in the plane. the rotor has an arc-shaped shape due to its convexity

Compared to the rotary engine described, the rotation of the rotor is turned to the side, in the housing ring in (1), the known rotary engine allows the reliability of the sealing of the working cylinders. which is connected to the system of creating high pressure,

However, in other respects, such an engine has the same disadvantages - a co-axle is installed in the central part of the rotor, which are characteristic of the engine described in (1): low specific power and low motor resource and efficiency. washer with slots oriented at an angle to

A rotary engine is known, which contains a core radius not equal to a right angle, the inserts are made of pus, which consists of arc-shaped cavities forming and with the possibility of movement in the spring and side covers with guide grooves and cuts of the rotor discs, the inserts have thrusts with roller - with inlet and outlet windows, placed in a cylindrical rotor made with the possibility of movement in the body cavity in the form of washer cuts, and discs with slots are installed on the fingers of the pistons, in which, with the possibility of movement, sliders can be inserted. To achieve a higher resolution, shaped profile inserts with working tattoos in the guide grooves between piston sliders, cylinders and double-acting pistons, additional sliders are installed. In addition, in the rotating motor with fingers, magnets can be installed along the generator rotor evenly along the generator rotor with the possibility of interaction with the guide grooves, along the generator cam (authorized certificate of the USSR Mo1455007, RO02857/00 , 1989) electric windings are installed in the casing rings, and

In comparison with the rotary engine described, the frame material allows to increase the temperature (2I, the known rotary engine |Z) has such perature of the surface of the side covers in the zone of the working stroke of the weight. pistons without temperature rise in other parts

The presence of two-way pistons allows us, because the thermal conductivity of metal-ceramics to increase the smoothness of the reverse transformation can be set much lower than the thermal conductivity of the forward movement of the pistons into the rotary movement of the metal mouth. This makes it possible to increase the efficiency of the engine, which torus due to the reduction of dynamic loads in the heat engine depends on the temperature difference on the "finger-groove" pair, which leads to some working body during and after the working stroke. th increase of the motor resource of the engine. Due to the execution of inserts in the rotor discs, the double-acting pistons increase their specific radial and in-plane power. The presence of reciprocating rotor pistons arc-shaped, with their convexity of reciprocating action instead of "wobbly" type pistons, does not cause sideways rotation of the rotor, allows to increase the volume of the working cylinders, and the smoothness of the reciprocating conversion causes an increase in engine efficiency. movement of the pistons in the rotation of the rotor, i.e. lower

However, just as in the known solutions, use dynamic loads and increase the motor resource, creaking on the roller finger causes a low and also eliminate the problem of "upper dead motor resource of the engine, lack of seals between the points" and increase the number of cylinders in the rotor, which the rotor and the case causes low efficiency. significantly increases the total working volume of the engine,

Execution of at least one piston in the ring of the housing in the rotary movement of the rotor in the upper dead internal cavity, which is connected to the point system and creates problems of mechanical resonance - creation of high pressure, allows to maintain a su between the frequency of rotation of the rotor and in its own time, the air gap between the rotor and the sealing of the cylindrical inserts is minimal, which is limited by the welded covers of the housing to ensure the effect

The proposed design of a rotary engine with a body in a cylinder 10. The side covers 2 of the housing contain a housing consisting of forming rings 1 (Fig. 1) made of a composite metal-ceramic material and side covers 2 of radial, which due to given thermal conductivity with multiple grooves 3. In the side covers 2 made of metal, the inlet 4 and 5 surfaces of the side covers 2 in the working area of the outlet 6 and 7 windows provide conditions for maintaining the temperature of the ceramic material. Cylinders 10 are placed in the cavity of the body, much higher than the surface temperature of the cylindrical rotor in the form of disks 8 (Fig. 2) from covers 2 in other areas of engine operation. This reduces the slots 9, in which inserts 10 are installed with the possibility of moving the energy loss of the working body to the heating of the side. The slots 9 are oriented to the cover 2 and leads to an increase in the efficiency of the engine. in the plane of rotation of the rotor, they have an arc-like shape in the movement of the piston 11 towards the center of the rotor, their convexity deflects the compression of the working mixture, which has arrived due to the rotation of the rotor, to the side. Inserts 10 are made of arc-shaped inlet window 5. At the end of the working stroke, they are moved in the slots 9 of the drive shaft 11 to maximally compress the working mixture that is in the rotor 8. In the inserts 10, pistons 11 are placed, two- came through the intake window 5, ignites. From-

the working stroke of the piston 11 from the center of the rotor is possible without a significant increase in dimensions and weight. At the same time, the spent working body is released through the window 6. At the end of the working stroke, the melting moment coaxially and in the same housing with the pistons 11 reaches its maximum removal by the heat engine, which can serve as a starter from the center of the rotor. During the next movement of the piston 11 for the heat engine, the electric generator at the center of the rotor releases the work of the heat engine, the electrodynamically driven working body through the window 7 with the simultaneous idling of the vehicle, the electric motor sucking the working mixture into the cylinder cavity of the vehicle using the transmission dra through the window 4. Next, the cycle of movement of the piston 11 of the heat engine. This allows to increase functioning. functional efficiency of the engine and opens wide

In order to increase the efficiency of the high-pressure engine 24, the gap between the rotor and the side piston fingers is made in the form of covers 2 automatically supported by the minimum half-fingers 22, spring-loaded from the inside with a spring at all engine modes. That is, it is carried out by 23, and with the possibility of deengaging them from the optimal gas-dynamic sealing, which provides 18 pistons 11 with sliders. Thus, during operation, the increase in efficiency, specific power and rotation of the electric motor, pistons 11 occupy the engine's idle moment. at the maximum radius of the rotor and does not
