A liquid cooled clutch having a floating pressure plate and an opposed backup plate between which a relatively rotatable friction disc is gripped, both of the floating plate and the backup plate having annular coolant passages, and liquid coolant being supplied simultaneously to the coolant passages of both plates. Each of the plates has a coolant inlet communicating with the coolant passages in the plate through restricted orifices which provide sufficient differential pressure to assure distribution of the coolant and to all of the coolant passages.
