Filed: 1992-08-18
Abstract: In a brake servo housing (10), a first chamber (12) is separated by a movable wall (16) from a second chamber (14) which is permanently connected to a vacuum source. In an inoperative position, a first controlled valve (20) interconnects the two chambers (12, 14) and separates them from an ambient air inlet (38). When it is operated, this valve (20) separates the two chambers (12, 14) and connects the first chamber (12) to the ambient air inlet (38). The housing (10) also contains a pressure chamber (42) having a compressed air inlet (46) connectable to a second controlled valve (50) and connected to the first chamber (12) in order to fill the latter with compressed air. Between the first controlled valve (20) and the ambient air inlet (38) there is a check valve (82) which allows ambient air to flow freely to the first controlled valve (20) but prevents compressed air from escaping into the environment. Thus a rapid build-up of pressure in the first chamber (12) is ensured when required.
