    An electronic compressed air system for vehicles, comprising a compressed air supply part (4) consisting of a compressor (7) and a compressed air consumer part (6) consisting of several compressed air consumer circuits (26, 28, 30, 32, 34, 36, 38) consisting of a pneumatic spring circuit (38) and operational brake circuits (26, 28) consisting of compressed air containers (90, 92) . The compressed air consumer circuits are supplied with compressed air by means of electrovalves (16, 18, 20, 22, 24). The pressure in the compressed air circuits is monitored by pressure sensors (72, 74, 76, 78, 80) whose pressure signals are evaluated by an electronic control unit (84) controlling the electrovalves. The electrovalve (24) of the pneumatic spring surface (38), which is embodied without a compressed air container, is closed in a flowless basic state whereas the electrovalves (16, 18, 20, 22) of the other compressed air consumer circuits (26, 28, 30, 32, 34, 36), particularly the operational brake circuits (26, 28) are open in a flowless basic state. When compressed air is required by the pneumatic spring circuit (38), the electrovalve thereof (24) is shifted into an open position by the electronic control unit (84) by means of data communication in order to establish a connection with the compressed air supply part (4) and/or the operating brake circuits (26,28) or compressed air containers (90,92) in order to refill the pneumatic spring circuit.
