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 ().

Foot brake valve of an air brake system

A control valve for applying a spring-loaded brake pressure to spring-loaded parts of a rear-axle wheel brake is pneumatically activated as a function of a parking-brake braking demand and a service-brake braking demand. A first control chamber is connected via a first control piston to a control arrangement in the control valve. During an adjustment of the first control chamber via the service-brake control pressure, the spring-loaded brake pressure at the working output is a function of the service-brake control pressure or of the parking-brake control pressure. The first control piston is connected to a third control chamber, wherein the pressure in the first control chamber acts on the first control piston in one direction, and the pressure in the third control chamber acts on the first control piston in the opposite direction. The first control chamber is selectively connectable to the third control chamber via a switchable bypass valve.

Control valve, electronically controllable brake system and method for controlling the electronically controllable brake system

A fluid-operated braking system () for a tractor-trailer vehicle includes a trailer control valve (), a parking brake module (), and an electronic control unit () electrically connected to the trailer control valve () and to the parking brake module (). A pressure fluid accumulator () of the braking system () is connected to a control pressure input (P) of the trailer control valve (). A redundancy circuit controls the control pressure input (P), even during a malfunction of the control unit (). The parking brake module () includes a control valve (), a redundancy valve () and a changeover valve () controlled by an electronic switch unit () with a holding function. When the control unit () malfunctions, the last error-free switching position of the control valve () or the redundancy valve is maintained until a operationally safe resting state is reached or the ignition system is switched off.

Brake system for a vehicle train and tractor therewith

A piston, e.g., for a control valve in a vehicle compressed air system, is housed in a cylinder in an axially displaceable manner along a longitudinal center axis separating a first cylinder chamber and a second cylinder chamber. The piston has a peripheral annular groove of approximately rectangular cross-sectional in which a sealing ring is inserted, the free end of which is disposed on the inner cover surface of the cylinder. The sealing ring defines, together with at least one groove wall, at least one pressure support chamber. The piston also comprises, in the region of the annular groove, at least one axial opening, which joins the at least one pressure support chamber to the associated first or second cylinder chamber. A pneumatic or hydraulic connection independent of any geometric deformations of the sealing ring is enabled between at least one cylinder chamber and the associated pressure support chamber.

Piston for a compressed air control valve

A sound damper for compressed air systems of vehicles includes a housing, an insulator and at least one web. The housing has an air inlet and an air outlet. The insulator is located in the housing, and the web is located in the housing such that it protrudes at least partially into the insulator. Air that flows through the housing from the air inlet to the air outlet is conducted by the web into the insulator.
