ABSTRACT:
A first seat of a valve element which forms a vacuum valve is axially spaced from a second seat of the valve element which forms an atmosphere valve. The diameter of the first seat is reduced so as to be on the same order as the diameter of the second seat. This allows the load which must set into a spring that is used to maintain a hermetic seal around the first seat to be reduced, in turn allowing an input which must be applied to initiate the operation of the brake booster to be reduced.
