The invention relates to a compressed air supply system (10) for a utility vehicle, said system comprising a compressed air inlet (26) that can be coupled to a compressor, a filter unit (14) that can be coupled to the compressed air inlet (26) via a supply line, a discharge valve element (20) that is coupled to a discharge outlet (24) and the supply line, an energy-saving control outlet (28) that can be coupled to a control inlet of the compressor, a supply line locking valve element (22) interposed between the compressor and the filter unit (14) and a first valve element (16) and a second valve element (18), the discharge valve element (20), the energy saving control outlet (28), the regeneration of the filter unit (14) and the supply line locking valve element (22) being controllable by the valve elements (16, 18). The invention is characterized in that the energy saving control outlet (28) can be controlled by the first valve element (16) and the discharge valve element (20) and the regeneration of the filter unit (14) can be controlled by the second valve element (18), and in that the supply line locking valve element (22) is closed during the regeneration phase of the filter unit (14) and can be transferred into a opened switching state when not in the regeneration state and when the discharge valve element (20) is closed and the energy saving control outlet (28) is aerated. The invention also relates to a method for operating a compressed air supply system. |
