Abstract

La présente invention se rapporte à un raccord pour transporter un fluide. Dans le raccord de la présente invention, une extrémité avant d'un manchon (240) disposé à une extrémité avant d'un embout mâle (200) est en contact avec un crochet de manchon (113) disposé à l'intérieur d'une tête de boîte d'embout femelle (110a) et une tête de boîte d'embout mâle (210a) qui entoure le manchon (240) est insérée dans une gorge de tête de boîte d'embout mâle (110b) définie dans une entrée de la tête de boîte d'embout femelle (110a) pour permettre à une extrémité avant de cette dernière d'entrer en contact avec un crochet de boîte d'embout mâle (114). En outre, une broche d'embout mâle (230) disposée au centre du volume intérieur du manchon (240) déplace une broche d'embout femelle (130) qui obstrue un second passage (112) d'une boîte d'embout femelle (110) pour ouvrir des passages (121, 122) d'une monture de tuyau (120), des passages (111, 112) de la boîte d'embout femelle (110), un passage (240b) du manchon (240), un passage (211) de la boîte d'embout mâle (210) et des passages (221, 222) de la monture de tuyau (220), en transportant et en fournissant ainsi un fluide d'une façon stable.
