Abstract: A compressed-air control device includes at least one first component, and a second component arranged so as to be movable relative to the first component. A molded seal is arranged in a groove of the first component, and is in contact with the second component. A first chamber formed on one side of the molded seal between the first and the second components can be charged with a first pressure, and a second chamber formed on the opposite side of the molded seal between the first and the second components can be charged with a second pressure. The molded seal together with the first component forms at least one overflow valve.

Abstract: A valve unit for an electro-pneumatic brake control is connected to an input of an air-quantity-boosting valve for the aeration/venting thereof. A double-armature solenoid valve includes primary and secondary armatures each spring-loaded and actuated by a common magnet coil. The primary armature is a switch for a vent valve; the secondary armature is a switch for an intake valve. When the coil is not drawing current, the armatures are in spring-loaded position, the intake valve blocking intake and the vent valve venting. When a first current flows through the coil, the primary armature enters switching position, with the secondary armature in spring-loaded position; the intake valve blocking intake and the vent valve blocking venting. When a second current greater than the first flows through the coil, both primary and secondary armatures are moved into switching positions, so that the intake valve admits air and the vent valve blocks venting.
