communicating between the two chambers in response to a pressing operation of the input shaft;
A poppet valve body and a plunger are provided in the valve body for shutting off the valve, and an output shaft has one end located in the front chamber and attached to the valve body, and the other end protrudes outside from the front shell. In a pressure booster consisting of
A radial hole is provided in the small-diameter cylindrical portion of the valve body at the proximal end side, and a stop key for regulating the return position of the plunger is provided in the radial hole to protrude in the radial direction, and the diaphragm or valve A stopper member is attached to the large diameter portion of the body, the tip end of which extends into the rear cylindrical portion of the rear shell and engages with the protruding end of the stop key, and the stopper member prevents the stop key from coming off. Features a pressure booster.
