ABSTRACT:
A rotary machine includes a stator housing having an inner surface defining a stator chamber. The housing further defines inlet and outlet ports through the housing into the chamber. A substantially cylindrical rotor is rotatably mounted within the chamber for rotation about a rotor axis. A plurality of vanes are slidably received in the rotor and movable therewith about the rotor axis during rotation of the rotor, with tip portions of the vanes projecting outwardly toward the inner surface of the stator housing. A continuous, substantially cylindrical cam surface means defines a camming surface substantially concentric with the inner surface of the stator housing. A cam follower is mounted on each of the vanes contacting the substantially cylindrical cam surface. A cam follower retaining means is free to rotate with respect to the cam surface and defines a substantially cylindrical retaining surface which is concentric with the camming surface. The cam follower means thus positions the vanes during rotation of the rotor.
