Vacuum brake booster

摘要

The object of the invention is to shorten the release time of a vacuum brake booster that can be actuated by means of an actuating rod and has a vacuum chamber and a ventilatable working chamber. To achieve this object, the invention proposes that the working chamber should be directly connectable to the vacuum source via a valve (17) that can be activated when the actuating rod (8) is relieved of load. <IMAGE>
