| 摘要 |
The invention relates to a level adjusting system for motor vehicles, with a compressed air reservoir (26) and a tire inflation connector (28), in which a spare wheel can be connected. The spare wheel can be inflated from the compressed air reservoir (26) with the aid of the controllable distribution valve (36), the pneumatically controllable distribution valve (18), which bridges the non-return valve (10), the air dryer (6) and the pneumatically controllable valve (20) which also connects the compressed air line (22). The spare wheel may also be inflated with the aid of the compressor (2) and the pneumatically controllable distribution valve (20). During the inflation process the compressed air line (22) is closed with the aid of the controllable distribution valve (24) so that no compressed air escapes into the atmosphere.
