Abstract:
A compressed air supply device (10.1) for vehicle compressed air systems which comprises, an air compressor (11) provided with an outlet, from said outlet a supply line (17) leads to an air drier (18), said air drier includes an inlet and an outlet side for supplying compressed air to a compressed air system,a safety valve (26) is connected to the supply line (17) to divert air to a pressure relief point (24) upstream of said air dryer and down stream of the air compressor,on the outlet side of the air drier (18) at least two compressed air consumer circuits, whose pressure is monitored by at least two pressure sensors, are connected to the supply line (17),control electronics (57) are provided, which are connected to the pressure sensors and at least one solenoid valve for controlling a regeneration of the air drier (18), and which control the compressed air supply of the air compressor (11),on the outlet side of the air drier (18), the supply line (17) branches into line branches that lead to at least two consumer circuits,a closing member disconnects the consumer circuits from the compressed air supply, the closing member being disposed in the respective line branch and switched by the programmable control electronics (57), the closing member is an overflow valve that is disposed in the line branch and is switched into the closed position with a pneumatic actuation means (41), and a 3/2-way pilot valve (44.1) is disposed in a control line of the pneumatic actuation means (41).
