で圧接する部材を備えた気圧式倍力装置。 A control valve mechanism is incorporated in the movable wall, which is operated by a push rod linked to the pedal and controls the pressure difference between the front and rear chambers of the movable wall in the housing.
An output member for extracting the forward propulsive force generated in the movable wall due to the pressure difference to the outside has a cylindrical rear end with a closed front end and is slidably fitted into the movable wall, and the control valve A small diameter hole in the movable wall that accommodates the front end of a valve plunger connected to the front end of the push rod in the mechanism is connected to a large diameter hole into which the rear end of the output member is fitted, and the inside of the rear end of the output member In a pneumatic booster in which a reaction disk made of a rubber material is arranged so as to be compressed between the movable wall, the valve plunger, and the output member during boost operation, the outer peripheral portion thereof is A return spring disposed in the front chamber that urges the movable wall rearward is interposed between the movable wall side end and the movable wall to transmit the force of the return spring to the movable wall, and an inner peripheral portion thereof. is fitted into the rear end portion of the output member and engaged with the reaction disk, and presses the outer circumferential seal portion of the rear surface of the reaction disk against the inner surface of the movable wall opposite thereto by the force of the return spring. Pneumatic booster equipped with parts.
