Abstract
A centrifuge for separating particulate matter from a fluid includes a housing having a base portion defining a fluid inlet, a rotor subassembly in the housing and including a centertube and a shaft. The shaft defines a plurality of fluid outlet ports and a fluid passageway in flow communication therewith. The fluid passageway communicates with the fluid inlet such that oil delivered to the centrifuge flows through a portion of the centrifuge shaft and exits from the fluid outlet ports. Press fit into the centertube is a baffle sleeve which is initially positioned so as to cover the fluid outlet ports when the baffle sleeve is in a first position. The baffle sleeve is movable with the rotor subassembly to a second position where the plurality of fluid outlet ports are uncovered.
