Abstract
Master clutch pressure and lubrication valve which consolidates both such functions or services for a power operated clutch pack, all to insure the necessary conservation of cooling lubrication oil at times when full engagement pressure on the clutch pack can have stabilized it against further clutch slip, but at times otherwise to insure a liberal flow of the cooling oil. By built-in delay of cooling flow change following clutch actuation in the valve, it makes the transition between the two rates of cooling flow by temporarily sustaining liberal circulation of the cooling flow for that initial time after full engagement pressure exerts itself on the clutch pack. Sometimes a clutch will continue slipping, just for that initial time.
