The invention relates to engine building, in particular, to rotary internal combustion engines.

Known rotary internal combustion engine containing a stationary housing with at least one working section and a compressor section, in turn containing at least one spring-loaded piston-protrusion, the surface of which is associated with the profiled surface of the rotor, mounted in the radial groove of the housing through the saddle with the possibility of radial moving all the way to the top of the saddle, in the side walls of which bypass channels are made, connected by a bar with a stop, the surfaces of which are paired with a hinge pushers rigidly fixed on an axis in the fixed bearings of the housing, a second hinge of cams mating to the profiled surface, fixedly mounted on the rotor, housing covers with bearing bearings, in which a cylindrical rotor rotates with at least one blade in the compressor section and with grooves in the working section in which piston-blades are mounted by means of a saddle with the possibility of radial movement up to the stop at the top of the saddle, in the side walls of which exhaust windows are made. Working chambers through calibrated holes in the piston-blades are connected to the piston cavities. Bypass channels are made in the troughs. The working sections contain articulated stops interfaced with the surface of the rotor and the profiled surfaces of the cam pushers, which are movably fixed on the axes in the fixed bearings of the rotor and the persistent articulated surface are mated with the stops of the piston-blade. In the end walls of the rotor, air blades are installed for cooling the rotor. Air compression process and working combustion process mixtures occur in separate sections. The working chambers are formed by the surface of the rotor, the profiled surface of the housing with protrusions evenly spaced and similarly located cavities and the surface of the spring-loaded piston-blades (see the description of the invention to RF patent N ° 2272910, IPC F 01C 1/356, F 02 B 53 / 08, publication March 27, 2006).

The disadvantage of this known rotary engine is its low reliability.

Known rotary internal combustion engine containing a stationary housing with a compressor section and at least one working section, housing covers with bearing bearings, in which a cylindrical rotor with at least one blade in the compressor section and at least one blade in the working section is installed , the air receiver, the separator-receiver and distributor, the compressor and working sections contain saddles located in the grooves of the body, in which spring-loaded septum tubes with seals, seat covers with compressed gas supply openings for controlling the position of the baffle pistons, bypass channels for equalizing the pressure on both sides of the baffle pistons before their radial movement, two o-rings in the rotor grooves on each side of the profiled rotor surface, seals for each blade ridge, the compressor section contains inlet channels, compressed air injection channels with check valves, holes in the seats for supplying compressed gas to the piston cavity (see Description of the invention to the patent of the Russian Federation N ° 2275507, IPC F Ol C 1/356, F 02 B 53/08, publication April 27, 2006).

The disadvantage of this known rotary engine, adopted as a prototype, is that the process of fuel combustion occurs at constant pressure, which leads to a decrease in thermal K.P.D. The task of the invention is to increase thermal KPD rotary engine by carrying out the process of fuel combustion at a constant volume.

The essence of the claimed invention lies in the fact that the rotary internal combustion engine contains: - a housing with an intake manifold, compressed air injection channels, check valves, bypass channels, combustion chambers, two for each working cavity with fuel nozzles, inlet two-seat valves with an electromagnetic drive check valves; -bearing bearings, in which a cylindrical rotor with inlet windows is installed, with a drive pulley of synchronizing shafts, with air boost blades, blades with seals on the ridges, o-rings are installed in the grooves of the edges; - baffle valves with seals associated with the profiled surface of the rotor mounted on shafts with cams interacting with cams of synchronizing shafts rotating with driven pulleys due to a belt drive from the drive pulley;

- air receiver; - housing of damping devices with damping springs, return springs, pistons, check valves, seals, bypass channels; - exhaust manifolds.

The invention is illustrated by drawings, where: in Fig.1 shows a rotary engine, a General view in longitudinal section; 2, the same is a transverse section A-A; Fig. 3 is a transverse section B-B.

The rotary engine comprises a housing 1 with an intake manifold 2, compressed air injection channels 3, check valves 4, by-pass channels 5, combustion chambers 6, two for each working cavity with fuel nozzles 7, inlet two-seat valves 8, check valves 9, bearing bearings 10, in which a cylindrical rotor 11 with inlet windows 12 is installed, with a pulley 13 of the drive of the synchronizing shafts 14 , with blades 15 for pressurization of air, blades 16.17 with seals 18.19 on ridges, along the edges of which grooves 20 are installed in the grooves, baffle valves 21, 22 with seals 23,24,25,26 paired with the profiled surface of the rotor 1 1, install lennye on the shafts 27 with cams 28, interacting with the cams 29 of the synchronizing shafts 14, rotating with driven pulleys 30 due to the belt drive from the drive pulley 13, air receiver 31, housing damping devices 32 with damping springs 33.34, return springs 35, pistons 36, check valves 37, bypass channels 38, exhaust manifolds 39.

Rotary engine operates as follows. When the rotor 1 1 rotates in the bearing supports 10 through the intake manifold 2 by the blades 15 of the air boost through the inlet windows 12 into the cavities formed by the profiled surface of the rotor 11 with the sealing rings 20, the housing 1, the blades 17 with seals 19, the baffle valves 22 with seals 25 , 26 air enters. Intake cycle. In adjacent cavities formed by the same surfaces, air is compressed and displaced through check valves 4 into the compressed air injection channels 3 and the air receiver 31. Compression cycle. At the same time, when the blades 16 pass through the inlet two-seat solenoid valves 8, the latter in each of the two combustion chambers 6 cut off the working cavities with one saddle and open the compressed air supply through the check valves 9 from the air receiver 31 with the other saddle. After the pressure in the receiver 31 and in the combustion chambers 6, the non-return valves 9 are closed and fuel is supplied through the nozzles 7. In the second combustion chambers 6, the inlet two-seat valves 8 shut off the compressed air supply from the receiver 31 and open the supply of working gas from the combustion chambers 6 to the working cavities formed by the profiled surface of the rotor 1 1 s o-rings

20, housing 1, blades 16 with seals 18, partition valves 21 with seals 23.24. Start of the stroke cycle. When the blades 16 are approaching the baffle valves 21 due to the bypass channels 5, the pressure is equalized on both sides of the baffle valves 21. Due to the residual pressure of the exhaust gases, and also by the action of the cams 29 of the synchronizing shafts 14 on the cams 28 of the shafts 27, the valves move- the baffles 21, 22 to the “open” position, freeing the passage for the blades 16, 17 and releasing exhaust gases into the exhaust manifolds 39. When the baffle valves 21, 22 move to the “open” position, the pressure on both sides of the pistons 36 remains about otherness due to the opening of the check valve 37. The braking valves, baffles 21, 22 takes place by compression damping spring 33. The end of the stroke cycle and the beginning of the release cycle. After the passage of the blades 16, 17 under the influence of damping springs 34 and return springs 35, the partition valves

21, 22 are returned to the closed position. The braking of the bodies 32 of the damping devices occurs by compressing the damping springs 34. The braking of the bulkhead valves 21, 22 is accomplished by compressing the gas by the pistons 36 in the bodies 32 of the damping devices. At the end of the movement, the gas pressure on both sides of the pistons 36 is equalized by the bypass channels 38. The rotation of the synchronizing shafts 14 is due to the belt transmission of torque from the drive pulley 13 to the driven pulleys 30. The remaining exhaust gases are displaced by the blades 16 through the gaps between the housing 1 and the partition valves 21 to the exhaust manifolds 39. The end of the exhaust cycle.

The implementation of the invention will improve thermal KPD rotary engine.
