  • Patent number: 11731600
    Abstract: An ABS pressure control valve assembly for controlling the fluid pressure in a pressure-medium-operated brake system of a vehicle having brake slip control, by which the brake pressure in pressure-medium-operated brake actuators is adaptively adjusted for a locking tendency of individual wheels of the vehicle. Two membranes of two membrane valves are clamped between two housing parts and an intermediate plate. Also described are a pressure-medium-operated brake system of a vehicle with brake-slip control, including at least one such ABS pressure control valve assembly, and to a method for producing such an ABS pressure control valve assembly.
    Type: Grant

  • Patent number: 9133956
    Abstract: An electromagnetic valve device includes an armature body; a coil housing; a static, hollow cylindrical armature guide tube; and at least one electromagnetic coil interacting with the armature body and accommodated in the coil housing; the armature body being guided in the static, hollow cylindrical armature guide tube and can abut against a head part, which closes off the armature guide tube at the head side, of the armature guide tube extending through a central passage opening of the housing and through a central opening in a yoke disk at the base side as to the coil and at least partially engaging under the yoke disk by a radially outwardly projecting annular base part, in which, for axial support of the head part, the head part is at least partially engaged over by a coil housing support part that makes contact with the head part in a contact region.
