FILTRATION ELEMENT OF FILTERING DEVICE, HOUSING OF FILTERING DEVICE AND FILTERING DEVICE Russian patent published in 2020 - IPC B01D46/10 B01D46/52 

FIELD: engine building; filters.

SUBSTANCE: invention relates to a filtering element for a fluid medium filtration device, in particular air, gas, fuel, oil, water, urea aqueous solution, etc., in particular, an internal combustion engine, in particular, an automobile. Filtration element (18) for filtering device (10) for fluid medium can be installed with possibility of replacement in filter housing (12) between at least one inlet (14) and at least one outlet (16) for fluid medium. Filter element (18) includes at least one filtering bellows (54) with at least one filtering medium and at least one seal (28), which is located relative to axis (20) of filter element (18) circumferentially on end face (52) of filter bellows (54). Seal (28) includes circumferential mounting area (56) with radial attachment portion (58) extending radially from the outside to the inside, and an axial attachment portion (60), extending at least one component of direction parallel to axis (20), and circumferential sealing region (62), wherein fastening region (56) with radial attachment section (58) and axial attachment section (60) envelops edge (52) of filter bellows (54). Rear side of radial fastening section (58) facing away from filtering bellows (54) forms retaining surface (59) for housing section (48), radially inward relative to axis (20). Rear side of axial fastening section (60) facing away from filtering bellows (54) forms a radially inner boundary of at least partially circumferential groove (64) in sealing area (62) to receive radially outer pressure section (32) related to body. Groove (64) on radially outer circumferential side located opposite to axial fastening section (60), when seen radially from inside to outside, is limited by circumferential sealing lug (66), which, if viewed in direction of axis, protrudes beyond axial fastening section (60). On outer side of sealing area (62) located in axial direction opposite to groove (64) relative to axis (20), there is circumferential sealing surface (70) acting at least in axial direction, which is located at greater axial distance from end face (72) of filter bellows (54), than retaining surface (59) of radial fastening section (58). Axial distance (74) between base of groove (64) and sealing surface (70) is greater than distance (124) between transition of base of groove (64) to axial fastening section (60) and transition of retaining surface (59) into sealing area (62), axial distance (78) between retaining surface (59) and sealing surface (70) is greater than axial thickness (80) of radial attachment section (58).

EFFECT: technical result is creation of filter element and filtering device, in which at least one seal can be placed reliably, stationary and with space saving, in particular, in the filter casing sealing chamber.
