This engine has a drawback - compressed air is supplied to the combustion chamber from the compressor through the compressed air line. Part of the power of the compressor and the engine as a whole is consumed to overcome the resistance of the line. This device is taken as a prototype of the present invention. The objective of the invention is to eliminate the noted disadvantage of the prototype. The technical result of the invention is to increase the efficiency of the engine due to the exclusion of the line from the design of the engine - the placement of the compressor directly at the combustion chamber. The technical result is ensured by the fact that a second damper disc is attached to the drive shaft of the damper disc, the second damper disc is made with the possibility of overlapping the cylinder, a cutout is made in the second damper disc to avoid collision between the rotor piston and the damper disc, to the second disc blades are attached to the damper, which are made with the possibility of pumping air into the cylinder sector, limited by the damper disk and the rotor-piston blade.

An engine with a three-bladed rotor is taken as an example. The engine consists of a housing, main shaft 6 (Fig. 6), a rotor-piston (Fig. 4), two damper disks 10, 12 (Fig. 7, 8) and a damper rotation mechanism (Fig. 6). The body consists of two covers - top (Fig. 3) and bottom (Fig. 5). The rotor-piston is attached to the main shaft. The main shaft is rotatably attached to the housing. The damper discs cover the cylinder. Each damper disc has a cutout to avoid collision between the rotor-piston blade and the damper disc. The rotor-piston is a disk to which the blades 5 are attached (Fig. 4). The blades are attached to the disk at the same distance from each other. A toroidal groove is made in the body - a cylinder in which the rotor-piston blades move. A spark plug 4, a fuel injector 3 are installed in the housing, inlet 1 and outlet 2 holes are made (Fig. 3). The mechanism for turning the damper discs consists of a drive shaft for the damper discs 11, to one end of which the damper discs are attached, and to the other end a bevel gear engaged with the bevel gear of the intermediate shaft 7, at the second end of which a cylindrical driven gear 9 is attached ( Fig. 6). Cylindrical drive gear 8 is attached to the main shaft 6 and engages with the driven gear 9 (Fig. 6). The gear ratio of the pair of gears driving / driven is equal to the number of blades, i.e. during the time during which the rotor-piston is rotated through an angle equal to the angle between the blades, each damper disk makes a complete revolution.

The engine works as follows. The process of engine operation is conditionally divided into two steps.

First step (Fig. 9). Fuel was injected through the nozzle into the sector of the cylinder, limited by the flap disc No. 2 (12) and the blade of the rotor-piston No. 2 (14), and the mixture was set on fire with the help of a candle. The pressure in the cylinder sector increased and caused the rotor-piston to rotate in the direction of arrow A. The combustion products formed in the previous step leave the cylinder sector, limited by the blade of the rotor-piston No. 1 (5) and the damper disk No. 1 (10), through the outlet in direction of arrow C. Both flap discs turn in direction of arrow B.

Second step (Fig. 10). Both damper discs are turned in the direction of arrow B. The damper disc No. 1 (10) has blocked the cylinder. The sector of the damper disk No. 2, containing the blades, turned out to be opposite the cylinder, sucks in air through the inlet in the direction of arrow D and pumps air into the cylinder sector, bounded by the damper disk No. 2 (12) and the blade of the rotor-piston No. 2 (14). The combustion products formed in the previous step leave the sector of the cylinder, limited by the vane of the rotor-piston No. 1 (5) and the damper disk No. 1 (10), through the outlet in the direction of arrow C.

Then the first and second steps are performed alternately.
