ABSTRACT:
A clutch for coupling an engine to a transmission gearbox engages and disengages automatically in response to engine speed variation. Springs hold the clutch pressure plate retracted from the clutch discs at idling speeds. As engine speed increases, centrifugally generated fluid pressure in the clutch lubricant overcomes the spring force and applies a modulated engagement pressure to the discs. An internal valve continuously supplies an oil flow to lubricate and cool the clutch components and to charge the centrifugal pressure-generating means. Retraction of the pressure plate shifts the valve to reduce the oil flow while the clutch is disengaged. This reduces viscous drag within the clutch and thereby assures a more controlled disengagement. Retainer means stores some of the reduced oil flow to assure that ample fluid is available to the centrifugal pressure-generating mechanism when engagement commences.
