Abstract
Rotary piston engines of the kind in which the air inducted into the working chambers of the engine passes through an induction passage which is formed in part in the rotary piston of the engine, the rotary piston thereby being cooled by the air flow therethrough, a member is secured to the main engine housing which forms an air reservoir chamber having at least the same and preferably twice the volumetric displacement of the engine in the induction passage between the part thereof formed in the rotor and an inlet port to the working chambers.
Claims15
A rotary piston internal combustion engine comprising housing means, at least one cavity formed within the housing means, a rotor rotatably mounted within the cavity, the peripheral wall of the cavity and the rotor being so shaped that working chambers are formed therebetween which vary in volume as the rotor rotates, an inlet port and an exhaust port in the housing means whereby gases may be respectively admitted to and exhausted from the working chambers, an air passageway in the housing means, at least one air passageway through the rotor which communicates with the air passageway in the housing means, and means secured to the housing means providing air reservoir chamber means with an internal volume which is greater than the volumetric displacement of the engine and which communicates with the air passageway in the housing means and with the inlet port whereby air inducted into the working chambers passes in sequence through the passageway in the rotor, the passageway in the housing means, the air reservoir chamber means and the inlet port.
