Abstract: Provided is a hollow rotor and method for making a hollow rotor for a gerotor system, the gerotor system including inner and outer rotors having interengaging lobed profiles. At least one of the inner or outer rotors comprises the hollow rotor, the hollow rotor including radially inner and outer walls radially spaced-apart in relation to a rotational axis of the rotor and walls extending between the radially inner and outer walls for closing axial ends of the hollow rotor. The radially inner and outer walls define therebetween a cavity, thus providing for a hollow or empty interior of the hollow rotor. At least one of the radially inner or outer walls forms a plurality of lobes circumferentially spaced-apart around the cavity.

Abstract: A positive displacement pump having a pump element having at least one variable volume displacement chamber, and a relief passage for relieving pressure from the displacement chamber when the displacement chamber is decreasing in volume and is not in communication with an intake or discharge port. A valve member, such as a reed valve, is provided to regulate flow through the relief passage.
