装置。Two air chambers, a front chamber and a rear chamber, are defined within the shell body by a power piston having a diaphragm and displaceably provided in the shell body via the diaphragm, and defined by a force actuating member. One chamber of a control chamber having two air chambers is provided with a valve mechanism associated with an input member for directly introducing atmospheric air into the one chamber, and the other chamber of the control chamber and the inside of the shell main body are said control chamber through a valve that communicates with a front chamber and connects one of these chambers to a vacuum source, and introduces atmospheric air into the rear chamber within said shell body in proportion to the differential pressure between the two chambers of said control chamber; It is characterized by using a pneumatic booster which communicates one chamber of the chamber with the rear chamber in the shell main body and transmits the thrust generated in the power piston to the output shaft provided on the power piston. Vehicle brake equipment.
