ABSTRACT:
A pump for moving a fluid has a housing with a cylindrical internal chamber accommodating a cylindrical piston. The piston is eccentrically secured to a shaft rotatably mounted on the housing. A baffle located in a recess in the housing controls the flow of fluid through the housing from a fluid inlet passage to a fluid outlet passage. A pair of cams eccentrically mounted on the shaft linearly move cam followers connected to the baffle to maintain an end of the baffle in close relation to the piston as the piston turns in the chamber.
