ABSTRACT:
A selectively engageable friction device, such as a clutch or brake, requires a supply of cooling fluid during engagement. The friction device is engaged by fluid directed to a piston through a passage in a shaft. A stepped diameter tube is slidably disposed in the shaft and is movable therein by fluid pressure to control the flow of lubrication and cooling fluid which is directed to the friction device during engagement and to prevent distribution of lubrication and cooling fluid when the device is disengaged.
