Abstract
An automotive type internal combustion engine driven accessory is connected to the engine crankshaft by a thermal and centrifugally responsive clutch mechanism that includes a centrifugally responsive ring responsive to higher engine speeds to provide slippage between the clutch parts to maintain the accessory drive at a predetermined maximum RPM, that speed level being increased in response to an excessive generation of heat due to the slippage to effect a greater engagement of the clutch and less slippage and therefore a reduction in the amount of heat generated.
