| 摘要 |
The invention relates to a compressed air supply device for a utility vehicle, having a compressor (14) which can be driven by a drive (10) via a pneumatically switchable clutch (12), and a valve (18) which can be activated by an electrical signal (16) in order to optionally feed compressed air to a switching inlet (20) of the clutch. The invention provides for the compressed air which is fed to the switching inlet (20) via the valve (18) to be extracted from a compressed air preprocessing system (26, 28, 30) via a non-return valve (40). |
