ROTOR INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: rotor engine has case 1 partially filled with fluid, jacket 2 received within case 1, rotor 2, which is provided with working chambers open from one end and positioned along generatrix of axle 12 of rotation, mounted in jacket 2 for rotation, and hydraulic motor 5. A base of case 1 is provided with discharging passage 6 whose inlet is in communication with inner space of case 1 and outlet with inlet of hydraulic motor 5 and with inner space of case 1 through check valve 20. Outlet of hydraulic motor 5 is also coupled with inner space of case 1. Jacket 2 is provided with side port 9, which interconnects inner spaces of case 1 and jacket 2, and bottom port 10, which is coincident with inlet of discharging passage 6. Radial cylinder 16 and opening 19, which is parallel to axle 12 of rotor 3, are provided in body of rotor 3 at bottom part of each working chambers 4. Spring-loaded piston 17 provided with roller 18 is received within cylinder 16. Axle 12 of the rotor is provided with force ring 13 whose outer surface is provided with groove 14 and hollow 15. When rotor 3 rotates roller 18 rolls over groove 14 and engages with hollow periodically. At the beginning openings 19 is coincident with inlet opening of a system for supplying of fluid and then with a spark plug of an ignition system. Sucking of the fluid is performed when roller 18 is set in hollow 15 and opening 19 is coincident with inlet opening of the system for supplying of fluid. Ignition of fluid occurs at the moment when roller 18 is set out from hollow 15 and opening 19 is coincident with the spark plug. In so doing open face of the working chamber 4 is coincident with bottom part 10 of jacket 2. EFFECT: enhanced efficiency. 1 dwg
