A sealing arrangement in a plug and-socket coupling with a pressure fluid passage, particularly between the spout of a liquid gas container and a discharge regulator mounted thereon.

摘要

In a plug-and-socket coupling, particularly between a spout (1) of a portable liquid gas container and a regulator (6) mounted thereon, in which a first coupling part (1) has a discharge outlet (5) adapted to receive a stud or protrusion (6) of the second coupling part, leakage to the surroundings from a pressure fluid passage through the coupling is impeded by an annular gasket (16) movably disposed within an annular chamber (15) between the stud (8) and a surrounding skirt (14). Between the gasket and the stud there is a passage for pressure fluid to the annular chamber behind the gasket for loading the gasket to closely abut against the internal surface of the skirt (14) and a surface (17) on the first coupling part.
