VACUUM ASSEMBLY FOR DRIVING A VEHICLE CLUTCH

摘要

The invention relates to a vacuum assembly for driving a vehicle clutch, applicable to transforming the clutch driving of any vehicle from the foot-driving of the clutch pedal to the hand-driving of the clutch button. The underpressure in an intake manifold (G.A.) of the vehicle engine is employed as a motive force for driving the clutch, said underpressure being achieved in a simple-acting membrane chamber (C.M.S.), or in a double-acting membrane chamber (C.M.D.) developping the force and the stroke required for moving the clutch fork (f.a.), the stages of coupling and decoupling the engine to the gear box being controlled by means of a pneumatic distributor (D.P.) operated using a control button (B.C.) located inside the motor vehicle, within the reach of the driver, the time required for the clutch skid in the moment of coupling the engine to the gear box being established by adjusting an adjustable choke (D.R.).
