Abstract

A vehicle, in particular a rail vehicle, includes a compressed-air-operated toilet device and a compressed air supply system which supplies compressed air to the toilet device during normal operation. The vehicle also includes an emergency compressed air source that is suitable for providing compressed air for continued operation of the toilet device in the event of a failure of the compressed air supply system.

First claim

1 - 15 . (canceled)

16 . A vehicle or rail vehicle, comprising:
a compressed-air-operated toilet device; a compressed air supply system supplying said toilet device with compressed air during normal operation; and an emergency compressed air source being suitable for providing compressed air for a continued operation of said toilet device in an event of a failure of said compressed air supply system.

17 . The vehicle according to claim 16 , which further comprises:
an air suspension device for providing air suspension of the vehicle, said air suspension device being connected indirectly or directly to said toilet device; and a control device enabling a transfer of compressed air from said air suspension device to said toilet device and operating said air suspension device as an emergency compressed air source, in the event of the failure of said compressed air supply system.

18 . The vehicle according to claim 17 , wherein said control device supplies compressed air from said air suspension device to said toilet device causing the vehicle to be lowered in the event of the failure of said compressed air supply system.

19 . The vehicle according to claim 17 , which further comprises a main air line extending through the vehicle, being connected both to said toilet device and to said air suspension device and supplying both said toilet device and said air suspension device with compressed air during normal operation as an integral component of said compressed air supply system.

20 . The vehicle according to claim 19 , which further comprises a main compressor connected to said main air line, said main compressor supplying said main air line with compressed air during normal operation, and said main air line and said main compressor forming all of said compressed air supply system or at least components of said compressed air supply system.

21 . The vehicle according to claim 17 , which further comprises at least one valve connected to said control device for directing compressed air from said air suspension device through said main air line into said toilet device.

22 . The vehicle according to claim 19 , which further comprises:
at least one additional air line provided in addition to said main air line, said at least one additional air line connecting said air suspension device to said toilet device; said control device directing compressed air from said air suspension device through said at least one additional air line into said toilet device and excluding said main air line.

23 . The vehicle according to claim 19 , wherein said control device is configured to enable compressed air to be removed from said air suspension device in order to supply said toilet device only when a pressure in said main air line falls below a predetermined minimum pressure.

24 . The vehicle according to claim 17 , wherein said control device allows compressed air to be removed from said air suspension device only when the vehicle is stationary.

25 . The vehicle according to claim 19 , which further comprises multiple units of the vehicle forming a train or railway train having a plurality of cars being coupled to each other, said control device being associated with one of said cars of said train or with a plurality of said cars of said train or with all of said cars of said train.

26 . The vehicle according to claim 25 , wherein said main air line ( 30 ) extends through all of said cars of said train.

27 . The vehicle according to claim 16 , wherein said emergency compressed air source is an auxiliary compressor.

28 . The vehicle according to claim 27 , wherein said auxiliary compressor is battery-operated.

29 . A method for operating a compressed-air-operated toilet device in a vehicle or rail vehicle, the method comprising the following steps:
providing compressed air from a compressed air supply system for operating the toilet device; and providing compressed air from an emergency compressed air source for a continued operation of the toilet device in an event of a failure of the compressed air supply system.

30 . The method according to claim 29 , which further comprises:
air-suspending the vehicle by using a compressed-air-operated air suspension device; and continuing to operate the toilet device in an event of a failure of the compressed air supply system by directing compressed air to the toilet device ( 100 ) from the air suspension device while lowering the vehicle.
