Abstract
A compressed-air supply device for commercial vehicles is provided. The compressed-air supply device may be connected electrically to an electronic control device that may actuate at least one control valve. The control valve has at least one inlet, one ventilating connection and one outlet. The compressed-air supply device has a control line which is connected to the control valve outlet and may be connected to a control inlet of a compressor and/or an inlet of a regeneration valve, has a supply line via which compressed air may be guided to the control valve inlet, and has a ventilating line connected to the control valve ventilating connection. The control valve may be ventilated via the ventilating line, and is configured such that at a predefined opening pressure in the supply line it pneumatically produces a fluid-conducting connection between the inlet and the outlet such that the control line is ventilated.
