Venting device

摘要

A venting device for insertion into an opening (2) of an enclosure having a wall (3) with an interior surface and an exterior surface comprises a body (11; 21; 31) having an insertion portion (12; 22; 32) for insertion into the opening (2) of the enclosure and a head portion (13; 23; 33). The body (11; 21; 31) has a passageway (14; 24; 34) that extends through the insertion portion (12; 22; 32) and the head portion (13; 23; 33) for passage of a fluid from the enclosure (7) to the ambient environment (6). The venting device further comprises an air permeable, water impermeable venting element (15; 25; 35) covering the passageway (14; 24; 34). An engagement section (16; 26; 36) is arranged circumferentially about the insertion portion (12; 22; 32) for engagement with the wall (3) of the enclosure. The engagement section (16; 26; 36) is radially deformable so as to provide a resisting force against withdrawal from the wall (3) when the venting device (10; 20; 30) is inserted in the opening (2), whereby the engagement section (16; 26; 36) is specifically adapted to permit insertion of the venting device (10; 20; 30) into openings of enclosures with different wall thicknesses.
