A foot brake valve (′) of a pneumatic brake system in a motor vehicle has an installation plate (′), on which a brake pedal () is pivotably mounted and to which a housing (′) of a control unit () is fastened. A spring-loaded plunger piston () in actuating contact with the brake pedal () is guided axially movably in an annular collar () projecting upward out of the installation plate (′). For fastening the housing (′) of the control unit () to the installation plate (′), the housing (′) has an intermediate flange () which is screw-connected to the main part of the housing (′) and has the annular collar (). The intermediate flange () is coaxially rotatably about a vertical central axis (), and is connectable in non-positively locking fashion to the installation plate (′) via a releasable clamping connection ().

A relay valve (') for a compressed-air system of a vehicle has a working pressure inlet, a working pressure outlet, a venting outlet and a controllable relay piston (). The relay piston () is axially movably guided and, at one axial end, has an annular, radially inner valve seat (). A sealing piston () is axially movably guided coaxially with respect to the relay piston (). The sealing piston () is pushed by a compression spring () toward the relay piston () and an annular, radially outer valve seat (), which is a part of a seat ring () fastened in an annular collar () of the housing bottom part (). The seat ring () is a deep-drawn component shaped as a cylindrical pot of a metallic material. The radially outer valve seat () is an axially protruding annular web with a gable-shaped axial cross section.

A control valve () of a compressed air system of a vehicle has a control piston (), guided in an axially movable manner in a housing cylinder (), two pressure chambers () separated from one another by the control piston (), which is sealed by at least one sealing ring () arranged on the outer circumference of the control piston (). The sealing ring () is a radial sealing ring having an axial length which substantially corresponds to the axial thickness of the control piston (). The sealing ring () has, on each of the two axial edges thereof, one respective radially obliquely outwardly directed sealing lip () which is in contact with the inner wall () of the cylinder (), and that a plurality of guide members () distributed over the circumference and formed between the two sealing lips () on the sealing ring ().

Control valve of a compressed air system

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.

A gear actuator for shifting a gear includes an alley switch actuator, a gear switch actuator and a shift finger, which can be moved by the alley switch actuator and the gear switch actuator for the purpose of transferring a switching movement to the gear. An alley switch sliding element is connected with the alley switch actuator, and a gear switch sliding element is connected with the gear shift actuator. The shift finger is supported movably at the alley switch sliding element and at the gear switch sliding element.

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.

A pneumatic cylinder includes a cylinder housing, a central piston displaceable longitudinally in the cylinder housing, a first trailing piston configured to work with a first trailing stop of the central piston and a first positioning stop on the cylinder housing, and a second trailing piston configured to work with a second trailing stop of the central piston and a second positioning stop on the cylinder housing. The cylinder housing comprises a base body in which the first trailing piston runs, a cylinder cover in which the second trailing piston runs, and an intermediate washer on which the first positioning stop and the second positioning stop are formed.

An apparatus for connection to a transmission actuator of an engine transmission includes sensors for sensing transmission shifting positions of a shifting device. An interface transfers the evaluation signals of the sensors to the control electronics of the transmission actuator. The sensors are arranged such that their spacing from the interface () is smaller than the spacing between the interface and the sensed shifting device.

A transmission actuator for a transmission includes a split sensor configured to detect a switching position of a split phase rod of the transmission that can be longitudinally displaced in a split sensor measuring direction. The transmission actuator further includes a gate sensor configured to detect a gate rod position of a gate rod of the transmission that can be longitudinally displaced in a gate sensor measuring direction, and a gear sensor configured to detect a gear rod position of a gear rod of the transmission that can be longitudinally displaced in a gear sensor measuring direction. Two measuring directions extend substantially parallel and span a measuring direction plane, and a third measuring direction forms an obtuse angle with the measuring direction plane.
