Embodiment Construction

[0032] The quick coupling R shown in Figures 2 and 3 comprises a female element A and a male element B arranged to be inserted into each other in the direction of axis XX', which is the common longitudinal axis of elements A and B.

[0033] The rear of the female element A is fluidly connected to the first conduit C 1 , while the rear of the male element B is connected to the second pipe C 2 . For example, male element B is mounted on a motor vehicle, pipe C 2 For supplying gas to a vehicle fuel tank (not shown) at a pressure of magnitude 250 bar, while female element A passes through line C 1 Connect to a pressurized fuel source (not shown). In this case, the female element A can be equipped with a gas station and intended to cooperate successively with a male element B installed on different motor vehicles.

[0034] The male element B comprises a tubular body 11, a pipe C 2 Connected to the tubular body 11 , and the tubular body 11 defines an internal fluid circulation ...

Abstract

The female rapid coupling element (A) is adapted to receive a male element (B) by insertion along a longitudinal axis (X-X'). It is equipped with at least one locking member ( 40 ), movable on an oblique axis (X27-X'27) and provided with an end ( 40 b) intended to be engaged in a groove ( 16 ) of a male element (B). A head ( 40 e) of the member is provided with at least one lug defining a first surface ( 40 h), oriented towards the end ( 40 b) and adapted to receive in sliding contact a corresponding surface ( 33 b) of a first component ( 33 ). The sliding plane (P1) between these surfaces ( 40 h , 33 b) is inclined at an angle of between around 75 DEG and 105 DEG with respect to the axis (X27-X'27) of translation of the member ( 40 ). According to the invention, the head ( 40 e) has two lugs arranged on either side of a rod for connection between the end ( 40 b) and the head.

Description

technical field [0001] The present invention relates to a female element of a quick coupling, and to a quick coupling mounted for handling fluid under pressure. Among other elements, the quick coupling includes such a female element. Background technique [0002] In the field of detachable connections of pipes through which fluid under pressure passes, it is known to use a coupling female element comprising means for locking the male element in the female element in the inserted configuration (that is to say, in the connected configuration) of the controlled device. [0003] From EP-A-1,531,297 it is known to use locking fingers movable in translation in a housing inclined with respect to the axis of insertion when the male and female elements are inserted into each other. Each locking finger is equipped with a projection that protrudes radially relative to the body of the female element and interacts with a control ring for controlling the position of the locking finger. ...
