This female quick-coupling element for a quick-connect coupling is able to cooperate with a male coupling element. A control ring is able to move in translation along a longitudinal axis between a first position and a second position. A blocking member prevents translation of the control ring as far as its second position. An element for the elastic return of a piston, integral in transverse movement with the blocking member, to its internal position is mounted in a housing of the first coupling element situated outside the housing of the piston, and fluidically isolated from the fluid-flow conduit. The first coupling element comprises transmission means, disposed between the return element and the piston, to return the piston to its internal position. |

1. Female quick-connect coupling element, for joining two pressurised-fluid pipes, this female coupling element being able to cooperate, along a longitudinal axis of the female element, with a complementary male coupling element, the female coupling element comprising:
a body through which a fluid-flow conduit passes, at least one locking member able to move between a position of locking the male element with respect to the body of the female coupling element in a coupled configuration of the coupling, and a release position, in which the female and male elements of the coupling can be uncoupled, a control ring able to move in translation along the longitudinal axis between a first position in which each locking member is held in its locking position, and a second position in which each locking member is able to move into its release position, a piston comprising an active surface in fluid contact with said conduit and being able to move sealingly in a housing passing through the body in a transverse direction from the fluid-flow conduit towards the outside of the body, the piston extending from the active surface opposite to the fluid-flow conduit, a blocking member the movement of which parallel to the transverse direction is integral with the movement of the piston, the piston being able to move from an internal position in which the blocking member does not block the movement of the control ring, to an external position in which the blocking member prevents the translation of the control ring to its second position, and at least one element for the elastic return of the piston to its internal position, wherein
the elastic return element is mounted in a housing of the body of the female coupling element situated outside the housing of the piston, the housing of the elastic return element being fluidically isolated from the fluid-flow conduit, andthe female coupling element comprises transmission means, disposed between the return element and the piston, for returning the piston to its internal position. |
