摘要： A fluid coupling for driving a cooling fan associated with a vehicle in a ram air stream. The coupling comprises relatively rotatable input and output members. The output member defines a chamber within which the input member rotates. The members have lands and grooves which define a shear space therebetween, and are cooperable with viscous shear fluid to transmit torque therebetween. The output member defines a reservoir chamber located forwardly of the lands and grooves in the ram air stream. An impact pumping ramp on the output member directs fluid from the shear space into the reservoir chamber during rotation of the input member. A temperature-responsive valve arrangement controls the flow of fluid from the reservoir chamber to the shear space. The output member has mounting pads against which fan blades are secured. The mounting pads are located axially on the output member between the lands and grooves, and the reservoir chamber and at least, in part, radially outwardly in the lands and grooves. This mounting results in an air cooling chamber being located axially adjacent the land and groove area and radially outwardly of the reservoir chamber. The output coupling member on the backside thereof has a unique construction which minimizes the overall axial length of the unit.
