ABSTRACT:
A brake booster, specifically, an improvement of a valve mechanism for booster is disclosed. According to the invention, the rear side of a curved portion of a valve element is surrounded by a retainer to be interrupted from the atmosphere. This prevents the atmospheric pressure from acting upon the curved portion of the valve element owing to the presence of the retainer.
