Abstract
A tubular member is disposed within a valve body and has a resilient retainer mounted around the outer periphery thereof. The inner periphery of the valve body is formed with an annular groove When a brake pedal is quickly depressed, an input shaft and the tubular member are driven forward through more than a given stroke relative to the valve body, whereby a projection of the retainer becomes engaged with the annular groove This produces and maintains a large opening in an atmosphere valve Accordingly, an output from a tandem brake booster can be increased immediately in response to a quick depression of the brake pedal.
