ABSTRACT:
A gerotor pump includes a pressure relief return flow guide system, composed of two distinct structures, a pressure relief port, and a flow guide. The pressure relief port separates the pressure relief flow and inlet flow, preventing them from mixing and causing turbulence in the inlet cavities. The flow guide is located at the end of the pressure relief port and the inlet to make the two flows smoothly merge in the inlet cavities.
