    摘要: A vacuum brake power booster is described wherein the return movement of a valve piston actuating a control valve is limited by a U-shaped element (17) slidable into a control housing (11). In order to improve the ventilation of the working chamber of the brake power booster initiated on actuation and to shorten the booster's response time, exit areas (42, 43, 44, 45) of ventilation ducts (38, 39, 40, 41) permitting an air flow into the working chamber (3) are formed radially outwardly of an area in the control housing (11) between the arms of the U-shaped element (17), the exit areas being confined by the outside walls (34, 35, 36, 37, 46, 47, 48, 49) of air evacuation ducts (28, 29, 30, 31) interconnecting the working chamber (3) and a vacuum chamber(4).

    摘要: A pneumatic brake booster with a booster housing, which comprises a first and a second housing shell and is subdivided into a working chamber and a vacuum chamber by an axially movable wall to which a pneumatic differential pressure can be applied, with the movable wall being formed of a diaphragm plate and a diaphragm abutting thereon that includes a radially inward sealing bead and a radially outward sealing bead for sealing the two chambers and the radially outward sealing bead is compressible between the housing shells. To improve the compression of the radially outward sealing bead, the radially outward sealing bead has a circumferential, uniform rib structure.

    摘要: To prevent a rolling diaphragm (13), which forms the movable wall (4) of a vacuum brake booster along with a metallic diaphragm disk (12), from becoming detached from an annular groove (52) accommodating a radially inner bead (32) of the rolling diaphragm (13), the rolling diaphragm is connected to the edge of the bead (32) located away from the (first) diaphragm disk (12). By connecting the rolling diaphragm (13) to the edge of the bead (32) located away from the (first) diaphragm disk (12), a pneumatic space (27) is defined by the rolling diaphragm (13) and the (first) diaphragm disk (12). Pressure occurring in the vacuum chamber(s) (28, 30) can be admitted to the pneumatic space (27).

    摘要: In order to enable a brake booster to operate both with a pressure above atmospheric and with atmospheric pressure without any negative mutual influences of the two energy types and without any change in the responding behavior of the device in case of failure of either energy type, the invention provides a pneumatic system which, during the operation of the brake booster with pressure above atmospheric, causes a force constituent to become active so as to counteract the forces caused by the increased pressure difference and acting on the control valve piston as well as on the control valve housing.
