A trailer braking system including:a supply line for connection to a continuous source of pressurised fluid;a spring brake, which has an apply position and a release position, and the spring brake moves to the release position when pressurised fluid is pro...

The valve device has a trailer brake valve for brake assembly and a trailer associated valve such as level control valve or lifting axle valve for an air suspension system. The trailer associated valve of air suspension system is integrated into device mai...

The device (5) has an emergency brake valve (19) controlling pressurization of a service brake based on pressure at a terminal (21) that is connected with a coupling head (2). A spring accumulator valve controls the pressurization of a spring brake based o...

The compressed air system (1) has an emergency brake valve (19) which is applied with a pressure of a container (4) depending on the pressure at a terminal (141). The terminal is connected with a coupling head (2). A shuttle valve is provided with an input...

The assembly (7) e.g. modular valve unit (9), has a supply port (15) and a spring-loaded port (28), where an emergency braking- and/or uncoupling function is integrated in the assembly and causes automatic aeration of the spring-loaded port when the supply...

The parking valve (14) has an output terminal (34) for compressed air pressurization of a spring-loaded parking brake (16). A supply port (35) is connected to an output terminal in a ventilation position. A pressure safety valve (31) is interposed in the v...

An inlet connection (24) works with a reserve pipe (20) and a connection (26) for a reservoir (28). A first outlet connection (OC) (37) operates brake control pressure for a service brake cylinder (46). A second OC (54) operates a release pipe that leads t...

The combivalve (1) has a housing (2) containing an emergency braking piston (3) acted on by a spring (20) and incorporating a spring-loaded double valve element (14), cooperating with an inlet valve seat (17) and an outlet valve seat (30), an operating dev...

When the brake pedal is depressed a pressure sensor (20) indicates the pressure required to apply the brakes (6) and the electric control system (23) adjusts a valve system (26,27,29) accordingly to admit air to the brake cylinder. Should the control unit ...
