Female connection element and quick connection including such an element

摘要

The element (2) has a bolt (20) moved with respect to a body (7) of the element between two positions, in which a male element (3) is retained in a sealed connection position and a downstream channel purging position, respectively. A control button (21) controls the displacement of the bolt towards one of the positions. The control button is slidably moved in a hole of the body. An O-ring joint (35) closes a space (41) between an external face (39) of the control button and an internal face (40) of the hole.
