Abstract:
A clutched device including an actuator and a clutch. The actuator can include a housing and a piston having a first, second, and third face. The first face and the housing can define a first chamber. The second face and the housing can define a second chamber. The second face can have a greater surface area than the first face. The third face and the housing can define a third chamber, isolated from the first and second chambers. A conduit can couple the first and second chambers. A vent can be coupled to the third chamber. A pump can pump fluid from a reservoir to the first chamber. A valve can selectively inhibit fluid communication between the second chamber and the reservoir. A shift element can be coupled to the piston for common translation and can move a clutch member between first and second positions.
