摘要： The invention relates to a seal arrangement comprising a cylinder element (104), a drivable, axially guided piston (110), a sealing element (100), and a working chamber (112) being delimited by the piston (110) and by the sealing element (100). The sealing element (100) comprises an asymmetrical cross-sectional profile having a sealing lip (138) which is formed by two converging sealing edges (130, 132) with different edge angles (134, 136). In the assembled state the sealing element acts upon the piston (110) with an asymmetrical contact pressure profile. With an installation in the correct position the sealing element (100) has a return-conveying effect in one of the movement directions (H) of the piston (110). In order to recognize the installation in the correct position the sealing element (100) is equipped with a marking (160).

摘要： The invention relates to a control valve (50) for a vehicle brake system having a first fluid connection (51), a second fluid connection (52), and a decompressed connection (53) toward the atmosphere, wherein an adjustment spring (55) applies a spring force to a control piston (54) moving in longitudinal direction on the decompressed side, said control piston completely releasing a fluid connection between the first fluid connection (51) and the second fluid connection (52) in an initial position, and to a corresponding vehicle brake system comprising such a control valve (50). According to the invention the control valve (50) comprises a valve body (60) having a seal seat (61) and a sealing element (59) coupled to a control piston (54), wherein a sealing region (59.2) of the sealing element (59) interacts with the seal seat (61) of the valve body (60) in order to limit an effective pressure present on the second fluid connection (52) to a predetermined maximum pressure value, wherein an effective diameter (58.1) of the control piston (54) is greater than or equal to an effective diameter (58.2) of the sealing element (59).

摘要： The invention relates to a pump assembly (10) for the synchronous pressurization of two fluid circuits, comprising two internal gear pumps (11, 11') disposed together in a pump housing (12) and rotationally driven by the drive shafts (16) thereof, the pinions (19, 19') of said pumps being located in the associated pump chamber and engaging in the internal gear (21, 21') thereof. The pump chambers of the internal gear pumps (11, 11') are separated from each other by a common separating wall (15), which is designed as a separate housing part and engages in a hollow cross-section of a housing part (13) forming the circumferential wall of one of the internal gear pumps (11, 11'). Suction channels (24, 24') and pressure channels (25, 25') associated with the internal gear pumps (1, 11') transition into a radially extending longitudinal section in the pump housing (12) following an axial longitudinal section in the lateral boundary wall of the associated pump chamber. According to the invention, the suction channel (24, 24') and the pressure channel (25, 25') of one of the internal gear pumps (11, 11') are integrated in the separating wall (15).

摘要： The invention relates to an internal gear pump (10) for a braking system, in the pump housing (11) of which an inner toothed hollow wheel (12) and a gearwheel (13) engaging in the toothing of the hollow wheel (12) are mounted to rotate about parallel axes, wherein the toothing thereof defines a tapering roughly crescent-shaped pump chamber, in which a filling piece (14) is arranged supported along the length thereof, the circumferential surfaces of which closely correspond to the head diameter of the hollow inner toothing or the gearwheel toothing and contact in a sealing manner with several tooth crowns covered thereby, wherein a radial supporting force acts over a longitudinal range of the filling piece (14) for improved sealing of a circumferential surface of the filling piece (14) against the tooth crowns supporting the circumferential surface. According to the invention, a loose fit is provided between the circumferential surfaces of the filling piece (14) and the opposing tooth crowns of the hollow wheel (12) and gearwheel (13) and the play acting on the filling piece (14) is partly eliminated by support forces acting in opposing radial directions which act on the filling piece (14) at a distance from each other.

摘要： The invention relates to a brake system for a vehicle, with a main brake cylinder (2), a fluid control unit (3') and at least one wheel brake (4.1 to 4.4), wherein the fluid control unit (3') comprises, for brake pressure modulation in at least one brake circuit (10', 20') a switchover valve (12), an intake valve (11) and a recirculating pump (15) for each brake circuit. According to the invention, the fluid control unit (3') has, for each brake circuit (10', 20'), a sliding valve (40) which is connected into a suction line between the recirculating pump (15) and the main brake cylinder (2), wherein the sliding valve (40) restricts the effective pressure on a suction side (42) of the recirculating pump (15) to a predeterminable maximum pressure value. In this case, the sliding valve (40) can be arranged in series with or parallel to the intake valve (11).

摘要： Conventional piston pumps that are currently used for braking systems are frequently prone to noise problems caused by pressure pulsations. In the vicinity of the outlet valve (24) the inventive piston pump (1) comprises a pressure chamber (31), a counter-pressure chamber (36) and a flexible wall (32), which separates the pressure chamber (31) from the counter-pressure chamber (36). The flexible wall (32) has an elastically resilient membrane (32b) that is mounted in an elastic flexible body (32a). The piston pump is used predominantly in anti-slip braking systems for motor vehicles.
