Abstract:
1. A viscous fluid clutch comprising: an input shaft; a rotor assembly coupled to the input shaft; an annular housing insert; a housing including a first housing portion cast around the housing insert and a second housing portion connected for rotation with the first housing portion and rotatably disposed on the input shaft; a coil assembly including a coil body and a coil cover, the coil body having a head portion and a shaft portion perpendicular to the head portion, the shaft portion configured to receive at least one coil lead; and a seal compressed between the head portion of the coil body and the first housing portion about the shaft portion of the coil body, the seal abutting the head portion of the coil body and the first housing portion; wherein the coil cover is coupled to the housing insert; and wherein the coil cover contacts a portion of the coil body proximate the seal to substantially prevent the coil body from deflecting under the force applied to the coil body by the compressed seal.
