Patent ID: 8491289

Claim:
A pump, comprising: an actuator mounted on a rotatable shaft; said actuator further comprising a clutch assembly; a sprocket adjacent said clutch assembly; at least one washer adjacent to, and in contact with, said friction drive sleeve; a spring member disposed between said sprocket and said at least one washer; and when said clutch assembly is not actuated, said friction drive sleeve will receive a minimal amount of force from said spring members, and said shaft will transfer a minimal amount of rotational force to said friction drive sleeve, and when said clutch assembly is actuated, said clutch assembly will apply enough force to said sprocket such that said sprocket compresses said spring member, causing said shaft to transfer an increased amount of rotational force to said friction drive sleeve; a pump mounted on said shaft, selectively engageable by said actuator; and said pump comprising: an inner gerotor; a friction drive sleeve connected to said inner gerotor, said friction drive sleeve rotatably mounted on said shaft; an outer gerotor operably associated with said inner gerotor; wherein when said actuator is actuated, said friction drive sleeve will receive rotational force from said shaft, transferring rotational force from said shaft to said inner gerotor, creating a pumping action between said inner gerotor and said outer gerotor.
