ABSTRACT:
Provided is an improved fluid operated clutch control system (80) of the normally disengaged type and control system (100) of the normally engaged type that both employ a control valve (22) operative to selectively provide a fluid signal from a fluid pressure supply source (24) to a first fluid operated actuator preferably in the form of a piston (9) operative in the case of system (80) to overcome a reslient biasing device (26) and move the clutch to the engaged condition upon receipt by the control valve of an actuating signal normally provided either by depression of a clutch pedal (50) for a standard transmission or by a sensor (52, 53) for an automatic transmission and in the form of a piston (9A) for system (100) operative to overcome a resilient biasing device (26A) and move the clutch to the disengaged condition. The improvement being characterized by systems (80) and (100) being respectively provided with an override device in the form of piston (31, 31A) that are each continuously connected to supply source (24) and are operative to overcome a respective resilient biasing device (48, 48A) and, in the case of system (80), move the clutch to the engaged condition when the fluid pressure falls below a predetermined value and, in the case of system (100) move the clutch to the disengaged condition when the fluid pressure falls below a predetermined value.
