ABSTRACT:
A booster utilizing fluid pressure which is provided with a power piston disposed between a constant-pressure chamber and a variable-pressure chamber for being actuated by the pressure difference between the two chambers, a control valve actuated by shifting operation of the input member for producing the pressure difference between the constant-pressure chamber and the variable-pressure chamber, a control member disposed, being in connection with the control valve, relatively movably to the power piston in the operation direction thereof, and a spring disposed between the control member and the power piston, whereby the elastic force variation of the spring, due to the relative shifting of the control member and the power piston while in operation, may be transferred by the control member to the control valve for regulating the operation of the control valve.
