Abstract
An oil cooled and hydraulically operated clutch assembly (10) in which the cooling oil is contained within the clutch housing (18) after cooling and is scavenged by scavenger means including a pitot-like tube (94) during rotation of the clutch housing (18). An output shaft (20) passes through an aperture in the rear of the housing (18), the forward end of which is secured to an engine flywheel (12). Sealing means (52, 84) provide an oil seal between the periphery of the output shaft and the aperture. An annular piston (56) is disposed within the housing and is caused to be moved between disengaged and engaged positions and is operable when in the engaged position to cause clutch disks (26) to be held between the piston (56), a reaction surface (76) on the clutch housing and steel plates (28) for rotation therewith. A non-rotatable annular member (24) extends between the lip (50) which forms the aperture and the output shaft (20) and provides various passageways.
