Embodiment Construction

[0039] Figures 1 to 14 The quick connect coupling R shown in includes a female element A and a male element or end piece B designed to cooperate along the axis X-X', which is, in fact, the longitudinal axis for both elements A and B.

[0040] By convention, one considers the front of an element A or B to be that part of said element that faces the other element when elements A and B are interconnected.

[0041] Rear part of recessed element A with first tube C 1 fluid connection, the first tube C 1It is itself connected to a source of pressurized fluid (not shown), for example a gas source such as liquefied petroleum gas (LPG) or hydrogen at a pressure of about 300 bar (bar). The rear of the male element B is connected to the second tube C 2 , the second tube C 2 Connect itself to means for utilizing or storing fluid from the aforementioned gas source. For example, tube C 2 Can be connected to the fuel tank on the motor vehicle.

[0042] The male element B comprises a ...

Abstract

This female quick-connect coupling element for releasably joining together pipes for pressurized fluid is equipped with a fluid flow duct (44) and with a valve (200) for controlling the flow of the fluid through the duct, the valve having a first piston (50) and a second piston (52) that are mounted to move along the same axis (Y-Y') relative to a body (40) of the female element (A). The first piston is suitable for co-operating directly or indirectly with a seat (47) formed by the body of the female element, so as to close the valve (200), while the first and second pistons are interconnected via mechanical link means (142, 144, 152, 154), and each of said pistons defines one of two opposite surfaces (502, 522) in contact with the fluid when the valve (200) is open. The mechanical link means (142, 144, 152, 154) between the first and second pistons (50, 52) are disposed outside the fluid flow duct (44).

Description

technical field [0001] The present invention relates to a female quick-connect coupling element and a quick-connect coupling that can be used to releasably connect two pipes for pressurized fluid together, and the quick-connect coupling device includes such a recessed element. Background technique [0002] In the field of releasably joining together pipes through which pressurized fluid flows, it is well known to employ female coupling elements which are provided with means for locking the male element in its fitting to the female element. The male element and the female element form the ends of respective ones of said tubes, ie controlled locking means in a structure in which tubes are interconnected. The female coupling element is usually provided with a control valve for controlling the flow of pressurized fluid. It is possible that said valve will be operated when a fluid under very high pressure, in particular liquefied petroleum gas (LPG) at a pressure of about 300 b...
