Female quick coupling element and quick coupling including such an element

Abstract

This female quick coupling () element () is intended to cooperate, by press fitting (F) along a press fitting axis (X-X), with a male element (). It comprises a body () centred on a longitudinal axis (X) of the passage of fluid and comprising a flat front face (), a relief valve () comprising a valve () housed in the duct for the passage of fluid and mobile along the longitudinal axis, a manoeuvring ring () mounted slidingly around the body and defining, at its distal end (), a mouth (E) for receiving the male element. The manoeuvring ring is provided with at least one relief () of engagement with a corresponding relief () of the male element. The female coupling element further comprises a safety ring () mounted around the body (), radially inside the manoeuvring ring (), mobile axially in relation to the body () between a first position and a second position. The female element further comprises means () for transforming, when the safety ring () is in its second position, a movement of rotation of the manoeuvring ring, about the longitudinal axis (X) and in relation to the safety ring (), into a movement of axial translation of the body () in relation to the manoeuvring ring ().
