ABSTRACT:
Rotational control apparatus (A) in the preferred forms of fan clutches is disclosed including shoulder bolts (78) extending through axially extending voids (146) formed in axially extending portion (66) and flange (76) of first and second shell housings (62, 68). The shoulder bolts (78) secure the shell housings (62, 68) together to prevent relative movement therebetween. The apparatus (A) further includes a piston (80) having tabs (144) extending from the outer periphery thereof into the voids (146) and including openings having bushings (134) therein for slideable receipt on the shoulder bolts (78). Springs (138) are mounted on standoffs (210) extending in the voids (146) and abutting with the shoulder of the shoulder bolts (78). A first O-ring (94, 234) is received on an axially extending, outer cylindrical surface of a first shoulder (92, 232) such that fluid pressure received in a cylinder (C) pushes the first O-ring (94, 234) against the annular, radially extending surface of the first shoulder (92, 232). In a preferred form, a second O-ring (238) is received on an axially extending outer cylindrical surface of a second shoulder (236). A step (240) includes an annular, radially extending surface for pushing the second O-ring (238) towards the annular, radially extending surface of the second shoulder (236) in the absence of fluid pressure in the cylinder (C).
