ROTOR INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: engine has housing 1 and casing 2 received in the housing. The housing is partially filled with fluid. Rotor 3 is mounted inside the casing for permitting rotation. The rotor is provided with working chambers 4 which are open from the one face. The chambers are arranged along the generatrix to rotation axis 12 of hydraulic motor 5. Discharging passage 6 is made in the base of housing 1. The inlet opening of the passage is connected to the internal space of housing 1 and outlet opening is connected to the inlet of hydraulic motor 5 whose outlet is in communication with the internal space of housing 1. Casing 2 has side port 9, which connects internal spaces of housing 1 and casing 2, and bottom port 10, which is coincident with the inlet opening of discharging passage 6. Radial cylinder 16 and opening 19, which is parallel to axis 12 of rotor 3, are provided in the body of rotor 3 at bottom part of each working chamber. Spring-loaded piston 17 provided with roller 18 is received in cylinder 16. Axle 12 of the rotor is provided with force ring 13 whose outer side has groove 14 and hollow 15. When rotor 3 rotates, roller 18 moves along groove 14 and interacts with hollow 15 periodically. Opening 19 is periodically coincident with the inlet opening of the system for supplying fluid and then with the spark plug. When opening 19 is coincident with the inlet of the fluid supply system and roller 18 enters hollow 15, fluid is sucked. When roller 18 leaves hollow 15 and opening 19 is coincident with spark plug, the fluid is ignited. In so doing, the open face of the working chamber is coincident with bottom port 10 of casing 2. EFFECT: enhanced efficiency. 1 dwg
