Abstract:
1. A valve arrangement for controlling a brake system having at least one spring brake cylinder and at least one service brake cylinder, which are of a trailer vehicle of a traction vehicle-trailer combination, comprising: a 3/2 way valve which, as a function of a control pressure present at its control inlet, connects either its connection, which is connected to an outlet of a control valve device to generate service brake pressure for the at least one service brake cylinder, or connects its connection, which is connected to a trailer-vehicle-side compressed air supply, to its further connection which is connected to the at least one spring brake cylinder; wherein the 3/2 way valve performs both a tear-off function and a shuttle function, and wherein application of a spring brake when a supply coupling head is no longer supplied with sufficient pressure occurs even if tearing off of a hose connection or leakage in the hose connection occurs between the supply coupling head of the traction vehicle and the supply coupling head of the trailer vehicle because the pressure at the supply coupling head of the trailer vehicle then also drops, so that automatic braking of the trailer is implemented in the event of tearing off of the hose or the leakage in the hose connection.
