Abstract:
1. A compressed air supply system for a commercial vehicle, comprising: a compressed air inlet coupleable to a compressor; a filter module coupled to the compressed air inlet via a delivery line; a discharge valve unit coupled to a discharge outlet and the delivery line; first and second valve units, the first valve unit being operatively configured to control a control inlet of the discharge valve unit and the second valve unit being operatively arranged in a regeneration air path for regenerating the filter module; and at least one pneumatically closable overflow valve, operatively configured to supply a consumer circuit coupleable to the compressed air supply unit with compressed air, wherein said at least one pneumatically closable overflow valve is actuatable by the compressed air supply system; wherein said one pneumatically closable overflow valve is assigned to a particular consumer circuit which, in an event of a failure of the overflow valve, is fillable with a higher priority than at least one additional parallel consumer circuit; and wherein upon closing of said overflow valve, at least one further consumer circuit is fillable before the consumer circuit coupleable to said at least one pneumatically closable overflow valve.
