る負圧式倍力装置。 A power piston and a diaphragm that divide the inside of the housing into a variable pressure chamber and a constant pressure chamber where negative pressure always acts; a valve plunger that is slidably fitted to the power piston and interlocks with a brake pedal via a push rod; and the valve plunger. a control valve consisting of a control valve that normally comes into contact with the rear end, and the control valve of the control valve is interlocked with the brake pedal together with the valve plunger, and comes into contact with the seat surface of the power piston to form the constant pressure chamber. cutting off communication between the pressure transformation chamber;
A negative pressure booster in which the valve plunger and the control valve are separated from each other to introduce atmospheric air into the variable pressure chamber to create a pressure difference between the two chambers, thereby generating an operating force in an output rod interlocked with the power piston, A negative pressure booster characterized in that the control valve is constituted by a plate-like member whose outer peripheral portion can slide airtightly within the inner hole of the power piston.
