Abstract
A valve mechanism of an automatic brake booster comprises a vacuum valve seat formed on a valve body to face forward, an atmosphere valve seat formed on the rear portion of a valve plunger, and a valve element adapted to be seated on the both valve seats from the front side thereof. The valve plunger is associated with a solenoid plunger which allows the valve plunger to extend therethrough to permit a relative displacement therebetween and which is integrally connected thereto at an advanced end position thereof. A resilient member is provided which normally maintains the solenoid plunger at the advanced end position relative to the valve plunger. This simplifies a valve mechanism in comparison to a conventional automatic brake booster, thus improving the reliability.
