ABSTRACT:
An improvement of a valve mechanism used in the booster is disclosed. A first and a second valve seat are formed so as to face forward while a valve element is disposed so as to face rearward in opposing relationship with both valve seats. Thus, the both valve seats and the valve element are disposed in an arrangement which is opposite from that used in a conventional valve mechanism. Such an arrangement allows the atmosphere valve to be located radially outward of the vacuum valve, thus permitting the diameter of the atmosphere valve to be increased as compared with a conventional booster. This enables the operational response of the booster to be improved.
