ABSTRACT:
In a clutch mechanism for rotatably coupling a pair of shafts by engagement between a first and a second frictional engaging element each rotatably affixed, respectively, to one of the shafts, there is provided a fluid pressure mechanism for establishing frictional connection between the first and second engaging elements. A rotary valve mechanism including a first and a second valve component operates to prevent slippage between the first and second frictional engaging elements only when the first and second valve components are in a particular angular relationship relative to each other where the fluid flow cross-section through the rotary valve mechanism is a minimum. Additionally, rotary lock means may be provided for releasably locking the first and second frictional engaging elements together when slippage therebetween is prohibited by the positioning of the valve components of the rotary valve mechanism.
