Patent ID: 7014026

Claim:
In a centrifugal clutch having a plurality of cam members interposed between a cover and pressure plate, the cam members being movable radially outwardly under centrifugal force to cause the pressure plate to move in a direction forcing a plurality of clutch members into clutching engagement, the improvement comprising: cam retainer means between said pressure plate and cover for guiding inward and outward radial movement of said cam members; first means for maintaining a predetermined spacing between said cover and said retainer means; second means for maintaining a predetermined spacing between said pressure plate and said retainer means including means biasing said pressure plate and said retainer means towards one another; and a series of circumferentially spaced resilient biasing means interposed between said cover and said retainer means and wherein said resilient biasing means is operative to undergo compression in response to continued radially outward movement of said cam members when the force exerted on said clutch members equals the force exerted by said resilient biasing means on said pressure plate and retainer means.
