FIELD OF THE INVENTION This invention relates to mechanical engineering, primarily to internal combustion engines.

The purpose of the invention is to obtain reliability and simplify the design of a rotary piston engine,

This goal is achieved by placing inside the cylindrical body of the engine of the cylindrical rotor with cylinders and pistons located in it, whose axes are located in the plane of rotation of the rotor and are inclined at a certain angle to the coordinate with this plane. In order to obtain reciprocating movement of the pistons, there are grooves in the liners of the side covers, the geometrical contours of which are shapes of the Cassini trochoidal line. The rotation rollers mounted on the ends of the axes of the piston rods of the rotor pistons move along these grooves. The reciprocating motion of the pistons through the rotor is transmitted to the rotational motion of the motor shaft.

Figure 1-2 shows a transverse longitudinal section of the proposed rotary piston engine,

The rotary piston engine contains a housing -1 with inlet and outlet annular grooves 15 and 17, inlet and outlet windows 16 and 18, a socket 6 for a candle 19, a rotor 2 with cylindrical working chambers 3 located at an angle to the coordinate axes of the plane of rotation of the rotor and the hollow cylindrical bore - 10 for free travel of the power axis - 13 with associated rods - 5 and rollers - 14, pistons - 4, shaft - 7 with main bearings -11, liners - 8 s grooves - 20 geometric contour of the trochoidal shape of the Cassini line, sides Covered covers - 9, covers - 12, bearing housings.

In the stationary housing 1, a cylindrical rotor - 2 with cylindrical working chambers - 3 and a hollow cylindrical bore - 10. It rotates clockwise together with a straight shaft - 7, on which it is mounted. When the rotor rotates

-2 with pistons rigidly connected to them through the axes of the rollers - 13 rods - 15 with rollers - 14, which are rolled along the groove

-20 shape of the closed geometric contour of the Cassini trochoid line, as a result, the trajectories of this line are copied in the plane of rotation of the rotor - 2 and rotational and reciprocating movements are made relative to the axis of the shaft - 7 and the reciprocating movement relative to the cylindrical working chambers

- 3, of the rotor - 2, since the trajectories of these piston movements are the summed trajectories of the Cassini trochoidal line in the given parameters. As the rotor rotates clockwise (Fig. 1 a, b / the volume of the chamber of the cylinder - 3 increases and combustible mixture is sucked into it through the lower outlet window and the groove - 16, - 15.

until the top of the piston reaches the bottom dead center of the stroke. Further (Fig. 1 b, c) the volume decreases and the working mixture is compressed to the top dead center (Fig. 1, c). When the volume becomes close to

5 to the minimum (Fig. 1, c) candle in accordance with the selected ignition timing will ignite the compressed charge of the mixture. The ignition pressure causes a rotational moment of the rotor - 2 and forces

0, the direct shaft associated with it, 7, is rotated. With further rotation of the shaft and rotor (Fig. 1, d, a), the exhaust windows-18 open and exhaust gases (Fig. 1, A) are released through the groove-17.

5 Thus, in each of the four chambers, a fresh mixture is introduced in succession, charge compression, ignition and expansion of combustion products, exhaust gas discharge, i.e.

0 duty cycle is a process characteristic of a four-stroke internal combustion engine. In the proposed embodiment, four working strokes are performed in one revolution of the rotor with the shaft. In this application of the proposed rotary piston engine, the structural elements and principles of the known piston and rotary engines are combined, eliminating their disadvantages and taking advantage of their advantages:

0 reduce dimensions and weight, improve smooth operation, simplify the distribution mechanism and the complexity of the gear transmission, reduce the number of critical parts and components and reduce

5 discharge of the working mixture with spent mixtures into adjacent chambers caused by leaks and vibrations of the sealing plates and the springs pressing them under inertia and the associated losses

0 fuel, reduce the ratio of the surface of the combustion chamber to its volume, increase the operating range of speed numbers, increase the symmetry of the thermal floor of the combustion chambers.

Ultimately, simplify the design, increase the reliability of operation and maintenance, increase efficiency, reduce the emission of harmful gases into the atmosphere.
