Abstract

FIELD: engines and pumps.

SUBSTANCE: invention relates to rotary internal combustion engines. Propose engine comprises housing (1), rotor (23) with vanes (24), compensating combustion chambers (6), operating combustion chambers (7), nozzles (16), air receiver (36), valves-baffles (18), drive shaft (34) with central gear (35), cylinders (2) with opposed pistons (2) with con rods (4) and hinges (5), inclined disk (28), receiver (37), intake (38), discharge (39) and bypass channels (17), valves (8 -14), cam shafts (26), camshaft drive gear wheel (25) and sun gears (27). Aforesaid valves-baffles, when in closed position, form together with rotor surface, vanes (24) and housing (1), the working chambers. Compensating combustion chambers (6) accommodate pistons (20) linked by rods (19) with valves-baffles. Camshafts (26) control valves (8-14) and valves-baffles (18) via rockers (22) and rods (21). Inclined disks (28) act on inclined washers (29) that transmit force to pistons (3) for them to force air into air receiver (36). Levers (32) prevent rotation of inclined washers (29). In working stroke, rods (19) and pistons (20) are forced by gas in compensating chambers (6) to compensate gas forces in working chambers causing transfer of valves-baffles in position "open". Compressed air coming from air receiver in compensating combustion chambers (6) make rods (19) transferring valves-baffles (18) into position "closed". Bypass channels (17) communicate via valves (12) with receiver (37). At the end of working stroke, receiver (37) equalises exhaust gas pressure in motion of valves-baffles (18).

EFFECT: higher reliability of valves locking and driving mechanism.

The disadvantage of this known engine, taken as a prototype, is the unreliability of the mechanism for fixing and moving the partition valves.

The task of the invention is to increase the reliability of the mechanism of fixation and movement of the valve partitions.

The essence of the claimed invention lies in the fact that the rotary internal combustion engine contains: a casing, a rotor with blades, combustion chambers, fuel nozzles, an air receiver, baffle valves when moving to the "closed" position, forming together with the profiled surface of the rotor, the blades and housing working cavities, a drive shaft with a central gear, diametrically opposed cylinders with two opposing pistons with connecting rods and hinges in each, an inclined disk connected by h bearings with inclined washers with pins, rotationally supported by the arms swinging in bearings, a receiver, compensating combustion chambers, containing pistons connected by rods to baffle valves, inlet channels, exhaust channels, bypass channels, valves connecting combustion chambers with inlet channels and with working cavities, valves connecting the working and compensating combustion chambers, valves connecting the compensating combustion chambers with exhaust and inlet channels, valves connecting the bypass to Nala with receivers and outlet ducts, camshafts, valves and performing control-valves through rocker baffles and rods, the gear drive camshafts satellites; moreover, the inclined discs act on the inclined washers transmitting force through the connecting rods to the pistons displacing the air into the air receiver, in the compensating combustion chambers the piston rods receive the gas force and serve to compensate for the gas force in the working cavities, aimed at moving the partition valves to the position " open "during the cycle of the stroke, and also for their braking and movement to the" closed "position when compressed air flows from the air receiver into the compensating combustion chambers at the end of the stroke the bypass channels through the valves, at the moment of the beginning of the movement of the bulkhead valves to the "open" position, are connected to the receiver, which equalizes the exhaust gas pressures when the bulkhead valves are moved.

The invention is illustrated by drawings, where figure 1 shows a rotary engine, a General view in longitudinal section; figure 2 is the same, a transverse section aa; figure 3 is the same, a transverse section bb. The rotary internal combustion engine contains:

- housing 1 with diametrically opposed cylinders 2 with two opposing pistons 3 with connecting rods 4 and hinges 5 in each, compensating combustion chambers 6, working combustion chambers 7, valves 8 (connect inlet channels 38 with working combustion chambers 7), valves 9 ( connect the working combustion chambers 7 and compensating combustion chambers 6), valves 10 (connect the working combustion chambers 7 with working cavities), valves 11 (connect the compensating combustion chambers 6 with exhaust channels 39), valves 12 (connect the bypass pipes Ala 17 with receivers 37), valves 13 (connect inlet channels 38 to compensating combustion chambers 6), valves 14 (connect bypass channels 17 to exhaust channels 39), nozzles 15 for supplying fuel to working combustion chambers 7, nozzles 16 for supplying fuel to compensating combustion chambers 6, bypass channels 17;

- air receiver 36;

- receiver 37;

- inlet channels 38;

- exhaust channels 39.

Rotary engine operates as follows. The inclined disks 28 rotating with the rotor 23 act through the bearings 31 on the runaway side of the inclined washers 29, which through the pins 30, hinges 5, connecting rods 4 transmit the force to the pistons 3, causing them to move back and forth. The levers 32 prevent the rotation of the inclined washers 29. When the pistons 3 move, the cylinders 2 are filled with air and displaced into the air receiver 36. Intake and compression cycles. The initial position before the stroke of valves 8, 9, 10, 11, 12 is “closed”, valves 13, 14 are “open”. Partition valves 18 are moved to the closed position. At the moment of touching by the partition wall valves 18 of the blades 24, the valves 10 open and the supply of working gas from the working combustion chambers 7 to the working cavities begins, formed by the profiled surface of the rotor 23, the housing 1, the blades 24, the partition valves 18. The start of the working stroke cycle. By supplying the working gas from the combustion chamber 7 to the working cavities, the partition valves 18 are braked 18. In the position of the partition valves 18 “closed”, the valves 13 are closed, fuel is injected through the nozzles 16 into the compensating combustion chambers 6, the valves are opened 9. Pistons 20 connected by the rods 19 to the partition valves 18, compensate for the gas forces in the working cavities aimed at moving the partition valves 18 to the "open" position during the stroke cycle. At the end of the stroke, when the blades 24 are approaching the baffle valves 18, the valves 9 are closed, the valves 8 open, the working combustion chambers 7 are blown with compressed air from the air receiver 36 through the inlet channels 38, the valves 10 are closed, the working combustion chambers 7 are filled with compressed air, the valves 8 are closed, fuel is injected through nozzles 15. When the blades 24 reach the bypass channels 17, the pressure is equalized on both sides of the baffle valves 18, the valves 11, 12 open, the valves 14 close, the pressure in the compensating combustion chambers 6 decreases to atmospheric. The pressure in the working cavities and receiver 37 is equalized. Due to the pressure of the exhaust gases in the working cavities and the receiver 37, the bulkhead valves 18 are moved to the “open” position, freeing the passage for the blades 24 and releasing exhaust gases into the exhaust channels 39. The valves 13 open, the valves 11 close, the valves 14 open. The end of the stroke cycle and the beginning of the release cycle. When the valves 13 are opened and compressed air enters from the air receiver 36 through the inlet channels 38 into the compensating combustion chambers 6, the partition valves 18 are braked and move to the “closed” position. The remaining exhaust gases are displaced by the blades 24 through the valves 14 into the exhaust channels 39. The end of the exhaust cycle. The rods 21 connecting the baffle valves 18 to the rocker arms 22 serve to correct the path of the baffle valves 18. The valves 8, 9, 10, 11, 12, 13, 14 and the baffle valves 18 are controlled from camshafts 26 driven from gear wheel 25. The rotation of the rotor 23, which is the carrier of the planetary gear including the central gear 33, the satellites 27, the central gear 35, is transmitted to the drive shaft 34.

The implementation of the invention will improve the reliability of the mechanism of fixation and movement of the valve walls of the rotary engine.
