Valve arrangement for compressed air system of vehicle, has ventilation valve having control element for opening and closing of valve and control pressure supply, where control element is arranged such that valve is normally open

摘要

The arrangement has an exhaust valve and a ventilation valve (3) parallelly connected with each other such that a volume of a compressed air system is deaerated at the same time by the exhaust valve and ventilation valve. The ventilation valve includes a pneumatically actuatable control element (4) e.g. diaphragm, for opening and closing of the ventilation valve, and a control pressure supply (5), where the control element is subjected to control pressure by the control pressure supply. The control element is arranged in such a manner that the ventilation valve is normally open.
