Title:
DUAL DRIVE GEROTOR PUMP
Document Type and Number:
WIPO Patent Application WO/2021/229315
Kind Code:
A1
Abstract:
A fluid pumping system comprises a housing, an electric motor, a rotatable first input, a rotatable second input driven by the electric motor, a gerotor including an inner rotor, an outer rotor; and a cam ring in sliding receipt of the outer rotor. The cam ring is selectively rotatable by one of the first input and the second input. The inner rotor is rotatable by the other of the first input and the second input. The housing includes a first fluid inlet passage on a first side of the cam ring and a second fluid inlet passage on an opposite side of the cam ring. Fluid entering a cavity between the inner rotor and the outer rotor flows parallel to the axis of rotation of the first input. The cam ring includes a radially extending outlet port and pumped fluid flows radially out of the cavity.
