摘要： The invention relates to a pneumatic brake servo, comprising a servo housing (1), divided into at least one working chamber (3) and at least one vacuum chamber (4) by means of at least one wall (2) which may be axially displaced by pressurising with a pneumatic pressure differential, an actionable input body (7) with a valve piston (9), an output body (14) for exerting an output force on a main brake cylinder, a control valve (12) arranged in a control housing (5) operated by the valve piston (9), which controls the differential pressure and an elastic reaction element (6), arranged in a control housing recess (25) which is in contact with a top flange (23) of the output body (14), the input body (7) acting on the reaction element (6) with an input effective surface (A1) and the output body (14) acting thereon with an output effective surface (A2) and the ratio of output effective surface (A2) to input effective surface (A1) determining the force multiplication ratio of the brake servo. According to the invention, a brake servo with very precise tolerances for force multiplication ratio may be produced by means of adjustment means for the output effective surface (A2) in assembled brake servos.

摘要： The invention relates to a device for fixing a power brake to the splash board of an automobile using an adapter, said power brake being activated by a plunger rod. A sealing element arranged between the adapter and the splash board also fits closely to the plunger rod so as to provide a radial seal. According to the invention, the power brake (1) has at least one connecting pin (10, 11) to ensure that the sealing element is correctly positioned when the power brake is assembled. Fixing elements (16, -, 14, 15) are configured at the ends for fixing the power brake (1) to the adapter (3) and a main braking cylinder to the power brake housing (20), said main braking cylinder being situated downstream from the power brake (1). The invention also provides that the adapter (3) has at least one cavity (17) for receiving the designated fixing element (16), and the sealing element (4) has at least one guide bush (22) which can be slid onto the fixing element (16).

摘要： The invention relates to a pneumatic brake booster (1) for a hydraulic motor-vehicle brake system, comprising a booster housing (2), which has a front and a rear housing shell (3, 4), and comprising at least one connecting pin (8), which is arranged in the booster housing (2) in such a way that the at least one connecting pin extends axially parallel to the center axis (A) and which supports the booster housing (2) from the inside by means of two supporting formations (9, 10) and which protrudes through the booster housing (2) from the inside to the outside on at least one side by means of an end segment (11). According to the invention, in order to ensure simple intermediate handling of the brake booster (1) before and during the assembly of the brake system and to improve the durability and corrosion resistance, the housing shells (3, 4) are arranged in such a way that the housing shells are each connected to the connecting pin (8) such that the housing shells are secured against being axially moved apart from each other.

摘要： The invention relates to a tandem-type pneumatic brake booster (1), in particular for hydraulic vehicle brake systems, comprising a housing (2) which is composed of a first and a second half-shell (3, 4), and the interior of which is subdivided into a front and a rear booster chamber (6, 7) by means of a partition (51). Said partition (51) has a central circular cavity (8) into which a control housing (9) or a cylindrical control housing extension (10) penetrates, and the partition (51) sealingly rests against the control housing (9) or the control housing extension (10) by means of a sealing element (11). The disclosed pneumatic brake booster (1) further comprises a first and a second movable wall (12, 13) which respectively subdivide the front and the rear booster chamber (6, 7) into a first low-pressure chamber (14) and a first working chamber (15) and into a second low-pressure chamber (16) and a second working chamber (17). The brake booster (1) also comprises at least one conduit between the first working chamber (15) and the second working chamber (17) in order to compensate the pressure between said two working chambers (15, 17). According to the invention, the conduit is designed as a cylindrical sleeve (50) which penetrates the partition (51) and the second movable wall (13), said sleeve (50) allowing forces to be deflected from the partition (51) to a vehicle-mounted wall.

摘要： The invention relates to a housing module (1) for a brake booster comprising a housing half-shell (3) for housing a moving wall (4), which subdivides an interior space of the brake booster into a low-pressure chamber (5) and into a working chamber (6), and for housing a control housing (11), inside of which a control valve (10) is situated. Said control valve controls a pressure difference that acts upon the moving wall (4), can be actuated by means of an actuating rod (9), and is comprised of two sealing seats (12, 13), which are arranged concentric to one another, and of an elastically deformable valve body (14). The invention is characterized in that the housing half-shell (3) is comprised of a number of parts consisting of at least one metal housing part (15) and of at least one plastic housing part (16).
