Abstract: An electromagnetic actuating device includes a pole sleeve that extends along an axial direction and an armature situated radially inside the pole sleeve. The pole sleeve has a first axial end and a second axial end. The armature is guided inside the pole sleeve. The pole sleeve has, in a region situated between the axial ends, recesses whose contours each change along the axial direction.

Abstract: An electromagnetic actuating device is described. The electromagnetic actuating device includes a pole sleeve, an armature disposed radially within the pole sleeve and a coil form of an electromagnetic coil disposed radially outside of the pole sleeve. The armature has a first armature end face at one end and a second armature end face at the opposite end. On or in the coil-form wall, the coil form has a longitudinal channel extending along the longitudinal direction of the coil form, by which a flow connection is created between the armature end faces.

Abstract: A hydraulic module includes a pump housing with an opening in communication with an exterior surface of the pump housing. A plurality of pump chambers are in communication with the opening. A plurality of pump elements correspond to the plurality of pump chambers, each of the plurality of pump elements being movable within the respective one of the pump chambers to increase the pressure in a fluid from a suction side of the pump chamber to a pressure side of the pump chamber. A motor has an output member extending into the opening of the pump housing and coupled with the plurality of pump elements. A channel is formed in the exterior surface of the pump housing. The channel establishes fluid communication between the plurality of pump chambers.

Abstract: A hydraulic unit for a braking system includes at least one motor-driven pump. A pump housing is configured to receive the at least one motor-driven pump. A plurality of connection ports are provided in the pump housing as bores intersecting an exterior surface of the pump housing and configured to be fluidly coupled with corresponding external brake lines. A plurality of internal fluid passages are provided inside the pump housing, including a plurality of connector passages, each in direct fluid communication with a corresponding one of the plurality of connection ports.

Abstract: The invention relates to a hydraulic unit of a vehicle hydraulic brake system having a hydraulic block, a storage unit, and a holding unit. The storage unit is inserted into the hydraulic block, and the holding unit is adjusted for holding the hydraulic block locally fixed to an associated vehicle. The storage unit is constructed with a holding surface which forms a section of the outer side of the hydraulic unit, and the holding unit engages with the holding surface of the storage unit in order to hold the hydraulic block locally fixed above the storage unit. Furthermore, the invention also relates to a storage unit where one outer surface of the storage unit which forms an outer side of the hydraulic unit is constructed as a holding surface for attaching the hydraulic block in the vehicle.

Abstract: A method of assembling a hydraulic fluid accumulator in a bore defined in a housing structure is disclosed. The method includes (a) inserting an annular seal into a second bore portion of the bore so that the annular seal is positioned in contact with the first ledge, (b) inserting a piston into the bore so that the piston is located in a first bore portion of the bore as well as the second bore portion of the bore, and (c) inserting a cover having an annular rim into the bore so that (i) the annular rim is positioned in contact with the annular seal, and (ii) the annular seal is located in an annular space defined by the first ledge, the annular rim, the piston, and an internal wall of the housing structure that partially defines the second bore portion.

Abstract: A housing block for a hydraulic unit of a vehicle brake system that retaining a piston pump and an eccentric element that rotates the piston. A motor drives the eccentric element within an eccentric chamber. The block has a cylindrical cavity within a hydraulic leakage reservoir and a fluid leakage path that begins near a lower most portion of the eccentric element chamber and extends to a cylindrical cavity by way of a passage defined by an intersection of the eccentric chamber and cylindrical cavity. A pressure equalization path extends from the eccentric chamber upwardly to a point intermediate the housing block and motor enclosure and into the motor enclosure to a location that is substantially above the eccentric chamber. A seal intermediate the motor enclosure and housing block is formed as a closed curve of mastic material encircling the motor shaft, eccentric chamber, hydraulic leakage reservoir hydraulic fluid leakage path, and pressure equalization path.

Abstract: The invention relates to a cylindrical filter element, which has a longitudinal slot in order to be able to expand the filter element elastically for the purpose of fitting in a circumferential groove. To prevent any fluid from being able to pass unfiltered through the longitudinal slot, the invention proposes to configure end faces, which delimit the longitudinal slot, such that they run in the secant direction or in the peripheral direction. This has the advantage that the end faces overlap and therefore the longitudinal slot is closed when the filter element is installed.
