Abstract

A compressed air-supply device for a utility vehicle includes a valve housing and an exchangeable air-drying cartridge. The air-drying cartridge has a filter device which cleans the air flowing from the valve housing into the air-drying cartridge. The filter device separates the pre-filter area facing the valve housing from the post-filter area that faces the air-drying cartridge and in which foreign particles captured by the filter device are collected. A non-return valve is provided parallel to the filter device, which prevents air flowing from the pre-filter area to the post-filter area but allows the air flow from the post-filter area to the pre-filter area. The non-return valve is arranged in the valve housing.
