A power transfer device (30) includes a shift collar (120) moveable between a first position and a second position, a rotatable member (121 ), a rotary to linear movement conversion mechanism (136) interconnecting the rotatable member and the shift collar (120), and a hydraulic actuator (122) operable to drive the rotatable member. The actuator includes a vane rotatably moveable within a cavity formed in a housing and a pump (128) selectively providing pressurized fluid acting on the vane. The vane is fixed for rotation with the rotatable member such that rotation of the vane causes the shift collar to axially translate. |
