ABSTRACT:
A fluid coupling device (15) is disclosed of the type including an output coupling assembly (67) and an input coupling member (81) with a shear space (90) disposed therebetween. The coupling device includes a valve assembly (117) to control the flow of fluid from a reservoir chamber (99) into the shear space (90). Movement of the valve assembly (117) is in response to variations in air pressure in a pressure chamber (59), tending to bias a piston (57) and shaft (93) in opposition to the force of a spring (113). Axial movement of the shaft (93) is translated into movement of a valve arm (127) in a plane parallel to the plane of a fluid port (119) by means of a valve actuation mechanism (109). In the subject embodiment, axial movement of a valve actuation piston (111) results in rotation of the valve assembly (117) about the axis of rotation of the device (15) for improved valve action in a remote sensing type of fluid coupling device.
