| 摘要 |
The invention relates to a level adjusting unit for motor vehicles, with a compressed air reservoir (26) and a tyre inflation connector (28), to which a spare wheel may be connected. The spare wheel may be inflated from the compressed air reservoir (26), by means of the controllable distribution valve (36), the pneumatically controllable distribution valve (20), 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 by means of the compressor (2) and the pneumatically controllable distribution valve (20). During the inflation process the compressed air line (22) is closed, by means of the controllable distribution valve (24), such that no compressed air escapes into the atmosphere. |
