気圧式倍力装置。[Claims for Utility Model Registration] A booster that is divided into a constant pressure chamber that communicates with a negative pressure source and a variable pressure chamber that selectively communicates with the negative pressure source or the atmosphere, by a power piston and diaphragm attached to the front of the valve body. a main body; a valve device disposed within the cylindrical portion of the valve body to switch communication between the variable pressure chamber and a negative pressure source or the atmosphere; an input shaft inserted into the cylindrical portion to actuate the valve device; In a pneumatic booster, the pneumatic booster comprises: an output shaft that outputs to the master cylinder the force that is assisted by the input from the input shaft by a power piston that moves due to the pressure difference between the constant pressure chamber and the variable pressure chamber; A filter for removing dust in the atmosphere is disposed, and a silencer having a passage formed of a gap between the filter and the inner periphery of the cylindrical portion is disposed on the opposite side of the filter from the valve device, and the input shaft. A pneumatic booster characterized in that a silencer having a passage formed by a gap between the silencer and the outer periphery of the silencer is arranged in sequence.
