Abstracts: In electro vacuum clutch, the clutch is operated with the help of vacuum created in vacuum cylinder. When vacuum is created in the vacuum cylinder by vacuum pump, the clutch would disengage. A solenoid operated valve is used, which control the vacuum pressure from the vacuum reservoir. When solenoid valve is open the vacuum reservoir is connected with the vacuum cylinder and piston is moved. Thus clutch is disengaged. Clutch remains engaged due to the force of the springs provided in the clutch itself.
