ABSTRACT:
A rotary machine particularly intended for use as a pump comprises a two-lobe lenticular rotor rotatably disposed within a pump chamber defined by an annular wall with an inner surface having at least in part a cardioidal configuration. A rectangular drive plate on a shaft is disposed within an elongated drive slot in the rotor while a circular guide disc fixed on an end wall of the pump casing extends into a second elongated guide slot in the rotor. The second guide slot is perpendicular to the first slot so that, during operation, the rotor effectively reciprocates and rotates relative to the guide disc. If desired, two such circular guide discs can be provided, one on each end wall of the pump casing, for reciprocation and rotation relative to two such second guide slots in opposite faces of the rotor.
