  • Publication number: 20250277544
    Abstract: A solenoid valve including a first connection, a second connection, an armature and a coil for moving the armature. The solenoid valve comprises: a first closure part which is coupled to the armature and opens or closes the first connection as a result of a movement of the armature; a second closure part which is coupled to the armature and opens or closes the second connection as a result of the movement of the armature; and a damping spring which is arranged between the first closure part and the second closure part and is configured to dampen the closing process of the first connection and/or the second connection.

  • Patent number: 12103508
    Abstract: A valve assembly for providing pressure control at an output port, including: an input port and the output port; a pressure sink; a first valve with a first control connection; a second valve with a second control connection, in which the first valve and the second valve are arranged in series between the input port and the pressure sink and between which the output port branches off; a first control valve to connect the first control connection to the input port or vents the first control connection in a controllable manner; and a second control valve to connect the first control connection to the output port or vents the first control connection in a controllable manner. Also described are a related anti-lock braking system, a commercial vehicle, and a method.

  • 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.
