Abstract
A power transmission device includes a rotatable input shaft, a rotatable output shaft and a ring gear fixed for rotation with the input shaft. A carrier is fixed for rotation with the output shaft. A pump assembly includes an inner rotor supported for rotation on the carrier and an outer rotor encompassing the inner rotor. The outer rotor is in driving meshed engagement with the ring gear. The pump provides pressurized fluid to one of first and second fluid ports. A flow restrictor is moveable to selectively restrict fluid flow relative to one of the first and second ports.
