ABSTRACT:
A roller-type positive displacement fluid motor comprises a substantially circular rotor disposed within a stator ring having a generally elliptical profile, the rotor having a plurality of slots formed in its surface, each slot guiding a cylindrical roller which contacts the inner surface of the stator ring and moves radially inwardly and outwardly as the rotor rotates. Inlet ports are located in a first end plate such that they are opened and closed by the leading and trailing faces of the slots, and outlet ports are located in an end plate such that they are opened and closed by the rollers contacting the inner surface.
