Embodiment Construction

[0026] Figures 1 to 3 Quick connector 1 is shown for two pipes C that will deliver pressurized fluid 1 and C 2 connected. In this specification and the appended claims, "upstream", "downstream" and similar terms refer to the direction of flow of pressurized fluid through the connector 1 in the figure 1 Arrow E 1 express.

[0027] The connector 1 comprises a female element 2 and an associated male part, which in this first embodiment is constituted by a male element 3 . The elements 2 and 3 are designed to engage one in the other in the direction of the axis Y-Y', said axis Y-Y' being the longitudinal axis common to the elements 2 and 3 .

[0028] Within the scope of the invention, the proximal part of one of the elements 2 or 3 is facing or close to the tube C to which said element is connected. 1 or C 2 and the distal portion is the portion of the elements facing each other and facing or close to another element when ready for engagement.

Abstract

This female element (2), for a quick coupling (1) for releasably joining together two pipes (C1, C2) conveying a fluid under pressure, is suitable for receiving a male portion (3) engaged along a longitudinal axis (Y-Y'). The female element (2) includes a latch (20) movable relative to a body (7) of the female element between a first position, in which it is suitable for retaining the male portion (3) in a leaktight coupling position, and a second position, in which it is suitable for retaining the male portion (3) in a position for purging the downstream pipe (C1). The female element further comprises a control member (21) for causing the latch (20) to move at least towards the second position, this member (21) being mounted to slide in an open bore in the body. According to the invention, the female element (2) includes a gasket (35) suitable for closing a gap (41) defined between an outer face (39) of the member and an inside face (40) of the bore.

Description

technical field [0001] The present invention relates to a female connecting element, and a quick connector comprising such a female element, for releasably connecting together two pipes conveying pressurized fluid. Background technique [0002] Document WO-A-2006 / 092503 describes a quick connector comprising a female element and a male element which are respectively connected to an upstream pipe and a downstream pipe and are adapted for axial engagement with each other. Opposite engagement of the male and female elements opens a valve member mounted inside the body of the female element, thereby communicating the upstream tubing with the downstream tubing. The female coupling element includes a latch slidably mounted inside the body of the female element and resiliently biased toward a state for locking the male element in the engaged state inside the female element. In order to separate the elements of the connector, the female element also includes a push button for slidi...
