Title: Rotary piston engine with eccentric cylindrical rotor - has rotating casing liner to minimise sealing blade sliding velocity
IPC: F01C1/348
Filed: 1975-12-20
Abstract: Engine has a cylindrical liner (6) fitted inside the casing (8), against which the blades (5) seal radially. At one end this liner is stepped, forming a sealing face for the blade ends and an axial journal bearing which runs on a central spigot projecting from the casing. A flat plate (7) which rotates with the liner makes a seal against the other end of the blades. Rotor and sleeve rotate together, either by virtue of some form of drive connecting them or due to the frictional force created by the blade press. In either case, the velocity with which the blades slide over the adjoining surfaces is greatly reduced. Holes through the sealing plate (7) connect the working chambers between the blades with ports in the casing (8) for the ingress and egress of fluid.
