DEFINITION

Classification: 417/462

(under subclass 460) Apparatus in which the cylinder is mounted on a fixed supporting structure for movement relative thereto, during operation of the pump, in a circular path of more than 360 deg. in a single direction about an axis other than the longitudinal axis of the cylinder (i.e., other than the axis of reciprocation of a piston therein), said cylinder and the piston therein being mechanically interconnected in a manner which causes reciprocation of the piston relative to said cylinder upon rotation thereof.
