ABSTRACT:
A spray clutch assembly has a first disc having an exterior surface and a second disc spaced apart from the first disc in a generally parallel relationship. A plurality of sprags are circumferentially spaced apart and pivotally mounted between the inner surfaces of the first and second discs. In addition, a plurality of spacer elements are mounted between the first and second discs to hold them at a predetermined distance. At least one spring is provided on an exterior surface of the first annular disc for biasing at least one sprag toward a predetermined position. The present invention preferably has a plurality of springs with each spring corresponding to an individual sprag such that the sprags are individually biased without influence from an adjacent sprag.
