  • Vehicle driveline having torque transfer device that is operated on fluid pressure
    Patent number: 10119578
    Abstract: A vehicle driveline having a torque transfer device and a fluid circuit for operating the torque transfer device. The fluid circuit has a motor, a pump driven by the motor, an actuator, and a pair of valves. The valves are arranged in the fluid circuit to control fluid circulation within the fluid circuit and can be operated such that fluid pressure in the actuator can be maintained (i.e., to maintain engagement of the torque transfer device) without operating the pump.
