Abstract:
1. A low permeability coupling device in an engine for coupling a tube ( 2 ) extended by a first endpiece ( 3 ) with a second endpiece ( 10 ) carried by the wall ( 1 ) of a member to be connected to the tube, the second endpiece ( 10 ) having two substantially coaxial walls ( 11 , 12 ) defining between them a blind annular housing ( 13 ) for receiving the first endpiece ( 3 ), wherein an elastomeric sealing element ( 15 ) extends between the inside face ( 11 a ) of the outer wall ( 11 ) of the second endpiece and the outside surface ( 8 ) of the first endpiece, while the inside surface ( 7 ) of the first endpiece has an elastomeric sealing element ( 20 ) in contact with the outside face ( 12 a ) of the inner wall ( 12 ) of the second endpiece when said first endpiece is placed in the above-mentioned housing ( 13 ), and further wherein said blind annular housing ( 13 ) confines hydrocarbon emissions.
