SEAL INTERFACE, AIR DRYER CARTRIDGE AND AIR CLEANER Russian patent published in 2024 - IPC B01D53/26 F16J15/46 

FIELD: vehicles.

SUBSTANCE: invention relates to seal interface (10) for creating a seal between at least one container (14) with a desiccant and at least one base (12a) of air dryer cartridge (12) for a vehicle, in particular a cargo-passenger vehicle. Seal interface (10) comprises at least one first receiving structural element (14a) associated with desiccant container (14), in which at least one first sealing structural element (16) is formed by first receiving structural element (14a); at least one second receiving structural element (12b) related to base (12a) of air dryer cartridge (12), in which at least one second sealing structural element (18) is formed by second receiving structural element (12b); and at least one sealing element (20), including resilient isotropic sealing element (20), located in the assembled state between first sealing structural element (16) and second sealing structural element (18), wherein relative to longitudinal axis of seal interface (10) at least one axial sealing surface (16a, 18a) and at least one radial sealing surface (16b, 18b) for contact with sealing element (20) in assembled state are formed by first sealing structural element (16) and second sealing structural element (18). Invention also relates to an air dryer cartridge for an air cleaning device for a vehicle, in particular a cargo-passenger vehicle, with at least one seal interface (10) mentioned above, and relates to an air cleaning device for a vehicle, in particular a cargo-passenger vehicle, with at least one seal interface (10) and at least one mentioned above air dryer cartridge. At least one axial sealing surface (16a, 18a) and at least one radial sealing surface (16b, 18b) comprise at least one sealing groove (16c), capable of providing a compensation or reserve volume for the sealing element in order to compensate for the change in the distance between the sealing surfaces, which differ during standard and target modes of operation of the seal interface.

EFFECT: simplification of design and functionality, improvement of sealing characteristics and convenience of creation of interface and installation of air dryer cartridge.
