Abstract
A female quick-connect coupling element for releasably joining pipes for pressurized fluid which receives, along a longitudinal axis, an end-piece of a male element, and has at least one locking member for locking the male element, and which includes a fluid flow duct and a valve for controlling the flow of fluid through the flow duct, which valve includes a movable piston element mounted to move relative to a seat, and wherein the female element also includes a discharge circuit for discharging fluid from the flow duct downstream from the valve seat and the flow duct including a hollow end-piece for bearing against a seal carried by a male element when fitted into the female element, and wherein the hollow end-piece includes an inner sleeve and an outer sleeve that are coaxial and mounted to move axially relative to each other, and in that a space defined between the two sleeves is in fluid communication with the discharge circuit.
