Abstract

L'invention concerne un ensemble raccord à haute pression et déconnexion rapide (1) comprenant un embout de raccord (100) relié à une conduite de fluide et qui s'emmanche dans un réceptacle (30). L'embout de raccord (100) comprend une partie d'emmanchement (101) présentant un orifice de fluide (107). L'orifice de fluide peut être en communication fluidique avec un orifice de canal de fluide (207) ménagé dans le réceptacle. Une douille (111) est disposée autour de la partie d'emmanchement et apte à coulisser sur la partie d'emmanchement (101) pour prendre une position sur la partie d'emmanchement (101) dans laquelle elle recouvre l'orifice de fluide de l'embout (107) et pour s'écarter de cette position. La douille (111) comprend un bord d'extraction (121) qui est apte à buter contre un épaulement d'extraction (213) du réceptacle (200), lorsqu'on extrait la partie d'emmanchement (101) du réceptacle, en faisant coulisser la douille (111) jusqu'à la position dans laquelle elle recouvre l'orifice de fluide de l'embout (107).
