Patent ID: 8887888

Claim:
A viscous clutch comprising: a stationary journal bracket defining a mounting shaft; an output member rotatably supported on the mounting shaft about an axis; an input member rotatably supported on the mounting shaft about the axis; a working chamber defined between the input member and the output member to selectively transmit torque therebetween when a shear fluid is present; a valve assembly configured to control shear fluid flow along a fluid path defined between a reservoir and the working chamber; and an electromagnetic coil configured to generate magnetic flux to control operation of the valve, wherein the electromagnetic coil is supported on the mounting shaft, wherein the mounting shaft extends axially through the viscous clutch from a front face to a rear face, with the rear face of the viscous clutch defining a mounting surface for mounting the viscous clutch at a mounting location, the front and rear faces located at opposite sides of the viscous clutch and facing in opposite directions.
