ABSTRACT:
A rotary machine for handling a fluid includes a housing having a rotor chamber and a rotor rotatably mounted in the chamber. The rotor has a plurality of generally radially disposed vane slots, and a plurality of vanes are slidably mounted in the vane slots and operable to define variable volume chambers for the fluid as the rotor rotates and the vanes move generally radially in and out of the vane slots. The vanes have projections projecting from the longitudinal ends thereof, and the housing has annular rings having inner cylindrical surfaces disposed to be engaged by projections. Grooves on the outer surface of the rings are operable to produce a layer of fluid between such outer surface and the housing to thereby minimize the frictional rotational resistance of the rings on the housing, the rings thereby being rotated in approximately synchronization with the rotor.
