摘要： A vehicle differential assembly is provided that includes a differential driven by an input and adapted to allow differing rotational speed between a pair of outputs. The differential includes a gear assembly connected to the outputs and a hydraulically-actuated clutch for selectively and variably coupling the outputs. A hydraulic pump is adapted to generate hydraulic fluid pressure for engagement of the hydraulically-actuated clutch. A variable-engagement clutch is operatively connected to the input and the hydraulic pump such that the input selectively drives the hydraulic pump during engagement of the clutch to provide hydraulic fluid pressure to the hydraulically-actuated clutch. A torque coupling including a variable-engagement clutch is also provided.

摘要： A solenoid operated three port pressure control valve assembly of the exhaust pressure bleed type. The valve for the inlet pressure supply port includes a pressure responsive diaphragm with the supply port obturator attached. A bleed orifice in the diaphragm provides viscous dampening of the movement of the obturator and minimizes inlet valve flutter. The valve assembly is disclosed in both normally open and normally closed configurations.
