PCT No. PCT/DE97/00917 Sec. 371 Date Feb. 12, 1999 Sec. 102(e) Date Feb. 12, 1999 PCT Filed May 7, 1997 PCT Pub. No. WO98/06614 PCT Pub. Date Feb. 19, 1998The energy supply device has a compressor for supplying at least one compressed air consumer. On the outlet end, the compressor communicates with a pneumatically controllable outlet valve. Furthermore, two pressure regulating valves are provided, with which control air can be conveyed to the outlet valve in order to switch the outlet valve into the outlet position. The first pressure regulating valve can be switched by control electronics in accordance with a pressure sensor that detects the pressure on the consumer end. The second pressure regulating valve can be switched directly by the pressure on the consumer end. The second pressure regulating valve switches at a greater pressure on the consumer end than the first pressure regulating valve. In the event of a failure of the control electronics or of the first pressure regulating valve, the second pressure regulating valve takes its place.
