ZWEILEITUNGSBREMSANLAGE FUER KRAFTFAHRZEUGE MIT ANHAENGER

摘要

The tailer brake control valve has a spring loaded element which balances the towing unit brake pressure with that of the trailer system, to isolate the connection if there is a leak. The supply line to the trailer brakes is tapped off the same valve using a simple duct integral with the valve. The brake lien connections between trailer and towing unit a simplified. Two sets of spring loaded pistons are mounted in the valve, which also acts as a monitor the two brake circuits on the towing unit.
