Title: Rotary engine with hollow cylindrical piston - has radial vanes creating variable volume chambers with timer controlled poppet valve
IPC: F01C1/356
Filed: 1975-10-01
Abstract: The rotary piston engine has a hollow cylindrical piston (24) rolling inside a casing (20) supporting by a low-friction bearing (56) on an eccentric (54) mounted on a shaft (50) coaxial with the casing. The outside dia. of the piston is 75-95% of the inside dia. of the casing and the whole moving assembly is so dimensioned that, as the piston axis moves in a circular path about the casing axis (32), the min. distance between piston and casing is small. Seals are fitted between the flat end faces of piston and casing, and there are several flat rectangular blades (60) constrained to slide radially in the casing so as to remain in permanent surface contact with the piston. Hence, an uneven number of variable volume chambers is created between piston and casing. Each chamber has poppet inlet (7o) and outlet valves, in a cylindrical part of the casing, operated by a timer on the main shaft (50). A spark plug may be fitted there.
