Abstract

L'invention concerne une cuve contenant un liquide, à laquelle un embout de distribution peut être fixé facilement sans force excessive. Selon l'invention, pour extraire du liquide de l'intérieur d'une poche souple (2), du gaz est amené à partir d'une ouverture d'amenée de gaz d'un élément (30) d'orifice. Le gaz amené est introduit dans un espace (S2) situé entre un récipient extérieur (1) et la poche souple (2) par un passage (31) d'écoulement de gaz entre la surface intérieure d'un corps (21) d'embout et la surface extérieure d'un élément (27) de siège de soupape, un passage (13) d'écoulement formé dans un bouchon (5) et un trou (12) formé dans un étrier (3). Lorsque le gaz est introduit dans l'espace (S2), la poche souple (2) se contracte et le liquide placé à l'intérieur de la poche est extrait vers l'extérieur par un tube (8), un passage d'écoulement entre une soupape (24) et le siège de soupape, un passage (26) d'écoulement de petit diamètre et un passage (23) d'écoulement.
