Document Type and Number:
Japanese Patent JPS5940661
Kind Code:
B2
Abstract:
A brake booster for automotive vehicles comprises a low-pressure casing which is sealingly subdivided into a low pressure chamber and a working chamber by an axially movable wall. Axially movable wall includes a flexible diaphragm abutting a diaphragm plate. The diaphragm plate extends with radial ribs through wide longitudinal slots of a central reinforcement tube of the low-pressure casing and transmits the boosting force from the diaphragm plate to a centrally located control valve housing. A sliding element axially slidable together with the movable wall is guided at the axially extending rims of each of the longitudinal slots and overlaps the rims of the associated one of the longitudinal slots adjacent the working chamber. A rolling diaphragm of the movable wall disposed between the diaphragm plate and the reinforcement tube, rolls over the sliding element upon the boosting force movement, the sliding element bridging the longitudinal slot at this point.
