Abstract: A valve body is described for a braking system of a motor vehicle, having an insulating element inserted into a passthrough opening of the valve body, which is embodied to insulate a contact pin with respect to a surface of the passthrough opening, the insulating element being embodied integrally with the passthrough opening. A hydraulic unit is described for the braking system of the motor vehicle.

Abstract: An electromechanical brake booster for a brake system of a vehicle includes: a booster housing; and a valve element, which is situated in a continuous receiving opening of the booster housing in a manner that allows an adjustment in relation to the booster housing, and which has a continuous central opening within which a valve piston is positioned or able to be positioned in a manner that allows an adjustment in relation to the valve element such that a driver-applied brake force is transmittable via an input rod to an output rod. In addition, a ball segment is situated or developed on the valve element, which contacts a conical seat of a disk of the electromechanical brake booster situated between the ball segment and the booster housing so as to allow an adjustment in relation to the booster housing.

Abstract: In an apparatus for the continuous thermal treatment of metal continuously cast material having a heating section, the metal continuously cast material having a heating section, the metal continuously cast material is led over two contact rollers, wherein the first contact roller is arranged at a first end and the second contact roller is arranged at a second end of said heating section. Both contact rollers are connected to a voltage source in such a way that a current flows through the metal continuously cast material between the first and the second contact roller. Here, electrical contact is made with one of the contact rollers via a sliding contact element, which is in electrical contact with a slip-ring disk arranged concentrically with the axis of said contact roller. The sliding contact element is arranged on a current-carrying element using a plug-in connection which can be detached by pulling and which has at least one resilient and electrically conductive fixing element.

Abstract: An electromechanical brake booster for a brake system of a vehicle includes: a booster housing; and a valve element, which is situated in a continuous receiving opening of the booster housing in a manner that allows an adjustment in relation to the booster housing, and which has a continuous central opening within which a valve piston is positioned or able to be positioned in a manner that allows an adjustment in relation to the valve element such that a driver-applied brake force is transmittable via an input rod to an output rod. In addition, a ball segment is situated or developed on the valve element, which contacts a conical seat of a disk of the electromechanical brake booster situated between the ball segment and the booster housing so as to allow an adjustment in relation to the booster housing.

Abstract: An arrangement is provided for attaching a contact tube to a shaft of a continuous resistance annealing system for wires, wherein a centered flange is mounted on one end of the shaft, the flange including ring attachment structures for shaft-centered attachment of a ring to the flange. The ring includes tube attachment structures for ring-centered attachment of the contact tube to the ring and flange attachment structures for shaft-centered attachment of the ring to the flange. In the method for attaching a contact tube to a shaft of a continuous resistance annealing system for wires, a corresponding arrangement is constructed. To this end, the contact tube is attached to the ring in a ring-centered manner by the tube attachment structures, if the attachment has not already taken place. The ring is subsequently attached to the flange in shaft-centered manner by means of the ring attachment structures and the flange attachment structures.

Abstract: The invention relates to a hydraulic unit for a hydraulic vehicle brake system having anti-skid control. The hydraulic unit includes a hydraulic block and an electric motor for driving hydraulic pumps inside the hydraulic block. The hydraulic block and electric motor are joined at a circumferential joint. For connection, the invention provides that the electric motor is provided with a radial flange, which is overlapped by a surrounding bead of the hydraulic block. The bead is designed so that it overlaps, in a radial inward manner, the radial flange of the electric motor by a joining process, for example, a surrounding caulking. The electric motor is sealingly connected to the hydraulic block in a simple manner by the surrounding joining process.

Abstract: A hydraulic unit is elastically supported by means of elastomer elements, through which bolts pass, on two legs of a mounting bracket that extend perpendicular to one another. The leg of the mounting bracket has recesses, open counter to the mounting direction of the unit, for receiving the elastomer element. With clamping means disposed on the bolt, the elastomer element is axially shortened and pressed against both the recess and side faces, located on either side of the recess, of the leg of the mounting bracket. With the shortened elastomer element, a positive and nonpositive engagement with the leg of the mounting bracket is achieved.

Abstract: A hydraulic unit (11) is elastically supported by means of elastomer elements (17, 18), through which bolts (15, 16) pass, on two legs (13, 14) of a mounting bracket (12) that extend perpendicular to one another. The leg (14) of the mounting bracket (12) has recesses, open counter to the mounting direction (45) of the unit (11), for receiving the elastomer element (18). With clamping means (34, 35, 36) disposed on the bolt (16), the elastomer element (18) is axially shortened and pressed against both the recess and side faces, located on either side of the recess, of the leg (14) of the mounting bracket (12). With the shortened elastomer element (18), a positive and nonpositive engagement with the leg (14) of the mounting bracket (12) is achieved.
