Abstract
A rotary machine of the type which includes a rotor rotatably mounted in a stator and carrying vanes mounted for radial movement to cooperate with the inner surface of the stator to, for example, compress a gas drawn into the stator housing through an inlet port. The necessary radial movement of the vanes during rotation of the rotor is accomplished by means of cam followers associated with the vanes which ride on stationary cam surfaces. The cam surfaces are round and have their axes positioned eccentrically with respect to the axis of rotation of the rotor. Tension springs draw the vanes radially inwardly of the rotor so that the cam followers are held in contact with the cam surfaces. This provides positive vane control and prevents vane lifting while minimizing contact between the vane tips and the stator inner surface.
