ABSTRACT:
Sealing joint between two housings (1, 2; 14, 15; 28, 29) connected by two orifices (7, 8; 9, 11; 31, 32) capable of being offset axially and/or radially, characterized in that it comprises two stays (18, 19; 33, 37), the first of which is provided with a packing means (21, 34) made of elastic material, intended to come up against one of the housings under axial compression, so as to provide a seal in the axial direction, while the second stay (19, 37) is equipped with a packing means (22, 36) made of elastic material, intended to bear on a surface of the second housing (14, 29) and working under radial compression, and in that the two stays (18, 19; 33, 37) are joined to one another by means of an elastic joint (24, 35) providing a seal between the stays and working under radial compression and/or axial shearing. The elastic joint (24) between the two stays (18, 19) increases the possibilites of compensating the offsets between the two orifices to be connected, while at the same time maintaining an excellent seal.
