The disadvantage of this famous rotary engine adopted for the prototype is the complexity of the design, the lack of maintainability.
The aim of the claimed invention is to simplify the design of the rotary engine.
The essence of the claimed invention consists in that the rotary internal combustion engine comprises a housing with an inlet manifold, compressed air injection channels, check valves, fuel supply nozzles, bypass channels, inlet valves with return springs and rockers, exhaust manifolds, control channels for locking mechanisms with pushers And stoppers, housing caps with bearing supports in which a cylindrical rotor with inlet ports is installed, with a camshaft drive pulley, air-blast blades, blades with seals on the ridges along the edges of which seal rings are fitted in the grooves, septum valves with seals, Coupled with the profiled surface of the rotor, mounted on shafts with synchronizing segments in the valve bodies, on which the camshafts with driven pulleys are fixed in the bearing supports, with cams for controlling the movement of the valve-partitions and with the control cams of the inlet valves, the casing of the damping devices with damping springs, Springs, pistons, check valves, seals, bypass channels.
The essence of the invention is explained by the drawings, wherein:
1 shows a rotary engine, a general view in longitudinal section
Fig. 2 is a cross-section AA
FIG. 3 is a cross-sectional view of B-B
FIG. 4 is a cross-sectional view of the B-B
The rotary engine comprises a housing 1 with an intake manifold 2, compressed air injection channels 3, check valves 4, fuel feed nozzles 5, bypass channels 6, intake valves 7 with return springs 8 and rockers 9, exhaust manifolds 10, stopper control channels 11 with Pushers 12 and stoppers 13, housing covers 14, 15 with bearing supports 16, 17 in which a cylindrical rotor 18 with inlet ports 19 is installed, with pulley 20 of drive of camshafts 21, with air pressure blades 22, blades 23, 24 with seals 25 , 26 on the ridges, along the edges of which in the grooves are installed sealing rings 27, the partitioning valves 28, 29 with seals 30, 31, 32, 33, conjugated to the profiled surface of the rotor 18, mounted on the shafts 34, 35 with synchronizing segments 36, 37 In the valve bodies 38, on which the camshafts 21 with the driven pulleys 40, with the cams 41 for controlling the movement of the partition valves 28, 29 and the control valves 42 for the intake valves 7, the casing for the damping devices 43 with the damping springs 44, 45 , Return springs 46, pistons 47, check valves 48, seals 49, bypass passages 50.
The rotary engine works as follows. As the rotor 18 rotates in the bearing supports 16, 17 of the covers 14, 15 through the intake manifold 2 by the air pressure blades 22 through the intake ports 19 in the cavities formed by the profiled surface of the rotor 18 with sealing rings 27, body 1, blades 23 with seals 25, Partitions 28 with seals 30, 31, 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. Compression cycle. As the blades 23 of the stopper control channels 11 pass, the pushers 12 cease to hold the partition valves 28 in the closed position via the rocker arms 13. Due to the residual exhaust gas pressure, and by the action of the cams 41 of the camshafts 21 on the synchronizing segments 36, 37, the shafts 34, 35 rotate in the valve bodies 38 with the partition valves 28, 29, moving them to the "open" position, To the blades 23, 24. When the valve valves 28, 29 are moved to the "open" position, the pressure on both sides of the pistons 47 remains the same due to the opening of the check valves 48. The energy of the movement of the partition valves 28, 29 is extinguished by compressing the damping springs 44. After The passage of the blades 23, 24, under the influence of the return springs 46, the damping springs 44, the baffles 28, 29 return to the "closed" position. In the "closed" position, the partition valves 28 are held by the stoppers 13 of the locking mechanisms, which are controlled by the pushers 12, depending on the pressure of the compressed air. The damping of the energy of the movement of the casing 43 of the damping devices occurs by the compression of the damping springs 45. The braking of the partition walls 28, 29 is effected by compressing the gas by the pistons 47 in the housings 43 with seals 49 of the damping devices. At the end of the movement, the gas pressure on both sides of the pistons 47 is equalized by the bypass channels 50. The rotation of the camshafts 21 in the bearing bearings 39 occurs by means of a belt transmission of the torque from the drive pulley 20 to the driven pulleys 40. At the same time, as the blades 24 of the intake valves 7, the latter are opened by the action of the cams 42 of the camshafts 21 through the rocker arms 9. The compressed air starts to flow from the compressed air injection channels 3 into the cavities formed by the profiled surface of the rotor 18 with sealing rings 27, body 1, blades 24 with seals 26, With seals 32, 33. When the volume of the above-mentioned cavities is equal to the volume of the combustion chamber, the intake valves 7 are closed by the springs 8 and the fuel is supplied through the nozzles 5. Start of the stroke cycle. When approaching the blades 24 to the valves, the partitions 29 by passageways 6, the pressure equalization on both sides of the valves, baffles 29, due to the residual exhaust gas pressure, but also by the action of the cam 41 of the camshaft 21, there is a moving valves, baffles 28, 29, "open" position, freeing the passage of the blades 23, 24 and releasing the exhaust gases in the exhaust manifold 10. The end of the stroke cycle and the beginning of the release cycle. After passing the blades 23, 24, under the influence of the damping springs 44 and the return springs 46, the baffles 28, 29 return to the "closed" position. The remaining exhaust gases are displaced by the blades 24 through the gaps between the body 1 and the baffles 29 into the exhaust manifolds 10. The end of the exhaust cycle.
The implementation of the invention will simplify the design of the engine, improve the manufacturability of manufacturing units and parts, maintainability and reliability.
