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 an adjustable pedal device comprising at least two pedals (1, 23), the initial position of which is adjustable. In a previously known pedal device, an actuator is rotatably articulated to the brake pedal lever while the lever is rotatable about a third shaft (A). Said design has the disadvantage that a second pedal, particularly a gas pedal, cannot be simultaneously adjusted according to said principle because the forces acting upon the individual pedals are not effective in the same direction. The invention relates to a pedal device which has a simple design and in which the initial position of said two pedals can be adjusted in a substantially uniform manner, the two pedals (1, 23) being mounted within a twistable support (3) while being rotated about shafts (B, D) that are offset one relative to the other.

摘要： The invention relates to a pneumatic servobrake comprising a housing (1) which consists of a first shell and a second shell (2, 3) and is divided into a working chamber (5) and a depression chamber (6) by means of an axially mobile wall that can be subjected to a pneumatic differential pressure. Said mobile wall (4) is formed by a diaphragm disk (7) and a diaphragm (38; 47; 53) which is arranged thereon and comprises a radially inner tight bead (27) and a radially outer tight bead (39; 48; 54) for sealing the two chambers (5, 6). The radially outer tight bead (39; 48; 54) can be fitted between the housing shells (2, 3) and is provided with a peripheral, homogenous rib structure in order to improve the fit thereof.

摘要： The invention relates to a brake servo unit comprising a valve piston (9) with a concentric seal seat (47). Said seal seat projects axially beyond a second seal seat (16) and the concentric seal seat (47) has at least one recess (48) for restricting the volumetric air flow. This permits the regulation and the noise behaviour of the brake servo unit to be improved.

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).
