ABSTRACT:
A reversible unidirectional flow gerotor pump (FIG. 1) has an externally cylindrical internally lobed rotor (36) internally meshed with an eccentrically located externally lobed male rotor having a smaller number of lobes (40) and the annulus runs in a cylindrical cavity in carrier ring 22 pivoted on pin 20 via slot 24. The carrier ring is located in a cylindrical cavity in the body of the pump and is free to translate along the line 18, with accompanied movement along the line 44, this movement occurring automatically when the direction of rotation of the driven rotor 40 is reversed, and resulting in continued pumping flow in the same direction through the pump.
