Abstract
A power transmitting component can include a differential, a first sump, a clutch assembly, a reservoir, a pump, and a fluid circuit. The pump can operate in a first mode to pump fluid from a reservoir to the piston chamber to move the piston to a second position. The pump can operate in a second mode to pump fluid from the piston chamber to the reservoir to move the piston to a first position. The fluid circuit can fluidly couple the reservoir to the first sump when the piston is in the first position and the pump is operated in the second mode. The pump can be configured to pump fluid from the first sump through the fluid circuit when the fluid circuit fluidly couples the first sump and the reservoir.
