• a bypass 48 is provided in the first part 40 a of the inner housing 40 openings 50 are provided, which connect the interior of the air dryer cartridge 10 with the bypass 48.
• a check valve 52 is also arranged in the bypass 48.
• the check valve 52 prevents compressed air from flowing unfiltered from the inlet opening 20 at the filter device 44 into the desiccant 60 through the bypass 48, but permits an air flow b past the filter device 44 in the regeneration mode of the air dryer cartridge 10.
• the check valve 52 is preferably formed of a plastic material (eg, an elastomer). It is preferably designed in one piece with the first part 40a of the inner housing 40.
• the check valve 52 is spaced from the wall of the cartridge housing 14 in this construction of the air dryer cartridge 10. Thus, it is also protected against mechanical stresses that could occur, for example, by deformations of the cartridge housing 14.
• a space region 65 radially outside of the check valve 52 may also be filled with desiccant 60. In this way, the space within the cartridge housing 14 can be used even more effectively for receiving the desiccant 60.
