Abstract
A rotary piston pump comprising a rotor mounted within a housing, the rotor having a pair of slidably mounted vanes on opposite surfaces. The inner wall of the housing acts as a cam surface to move the vanes inwardly, and centrifugal force or a combination of centrifugal force and biasing causes the vanes to move outwardly. The rotor is eccentrically mounted within the housing and the housing interior walls are of irregular configuration, whereby fluid from an inlet is moved by the vanes through the housing to an outlet. This rotary piston pump is of economic construction, serves a variety of applications and is easy to service.
