Compressed-air supply device for commercial vehicles

摘要

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.

主权项

1. A compressed-air supply device for commercial vehicles which is electrically connectable to an electronic control device, comprising:
at least one control valve actuable by the electronic control device, the control valve having at least one inlet connection, one venting connection and one outlet connection; a control line connected to the control valve outlet connection, the control line being connected to at least one of a control inlet of a compressor and an inlet of a regeneration valve; a supply line arranged to supply compressed air to the control valve inlet connection; a venting line arranged to vent the control valve from the control valve venting connection; wherein the control valve is configured to establish a fluid-conducting connection between the control valve inlet connection and the control valve outlet connection using pressure in the supply line when a predetermined opening pressure is exceeded in the supply line.
