Claims

[Scope of utility model registration request]

A first cylinder part and a second cylinder part that are coaxially continuous.
A boost cylinder consisting of a cylinder part,
A tandem in which a first piston inserted into the boost cylinder and inserted into the first cylinder part and a second piston inserted into the second cylinder part are connected in tandem via a rod. a clutch rod protruding from a third piston that is inserted into the second cylinder portion and faces the second piston at an appropriate distance; a clutch master cylinder that generates hydraulic pressure and introduces it into the second cylinder section between the second piston and the third piston via a hydraulic pipe; and an air supply controlled by a control unit for supplying pressurized air from an air tank. a compressed air pipe introduced into the first cylinder portion via a solenoid valve and urging the tandem piston toward the third piston;
a relay valve that is inserted into a bypass air pipe that introduces pressurized air from the air tank downstream of the air supply solenoid valve of the compressed air pipe and reduces the air pressure from the air tank in conjunction with the output oil pressure of the clutch master cylinder; a double check valve that is inserted into the junction of the bypass air pipe with the compressed air pipe and introduces the greater of the discharge pressure of the relay valve and the discharge pressure of the air supply solenoid valve into the first cylinder; A clutch booster that can be used both automatically and with the foot pedal.
