Abstract: 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.

Abstract: A female element quick coupling for releasably joining two pipes conveying a fluid under pressure and which receives a male coupling wherein the female element includes a latch movable relative to a body of the female element between a first position, in which it retains the male portion in a leaktight coupling position, and a second position, in which it retains the male portion in a position for purging a downstream pipe. The female element further includes a control member mounted to slide in an open bore in the body for causing the latch to move at least towards the second position. This female element includes a gasket for closing a gap defined between an outer face of the member and an inside face of the bore especially at high purging pressures.

Abstract: A female rapid coupling element is adapted to receive a male element by insertion along a longitudinal axis (X-X?) and includes at least one locking member which is movable along an oblique axis and has an end engageable in a groove of a male element. A head of the locking member is provided with at least one lug defining a first surface oriented towards the end and adapted to receive in sliding contact a corresponding surface of a first component. A sliding plane (P1) between these surfaces is inclined at an angle of between approximately 75° and 105° with respect to the oblique axis of translation of the member. The head has two lugs arranged on either side of a rod or stem that extends between the end and the head.

Abstract: A quick connect and quick release coupling for connecting two pipes, including a male element and a female element that are axially fitted and interlocked one inside the other and wherein a locking mechanism retains the male element in a coupled position and a temporarily retaining mechanism immobilizes the male element, after its release by the locking mechanism, in a position for flushing a pipe connected to the male element. The locking mechanism is controlled by a sleeve that slides relative to a body of the female element. When the temporarily retaining mechanism retains the male element in flushing position, it is subjected to a first force (E1) derived from a pressure (P) of the fluid flowing (F) from the male element outwards and to a second force (E2), opposite to the first, exerted by elastic return means which, when the pressure (P) drops to a safety threshold, moves the temporarily retaining mechanism into a position for releasing the male element from the female element.

Abstract: The coupling comprises a male plug (3) and a female element (2). A retaining latch (20) for retaining the plug (5) in the female element (7) is movable between a first position in which said latch (20) is capable of retaining the plug (5) engaged to a first depth in the female element (7) in which it is connected in leaktight manner to said female element, and a second position in which said latch (20) is suitable for retaining the male plug (5) engaged to a second depth that is smaller than the first depth. The latch (20) is configured in such a manner as to be returned (F3) towards the second position at least in part by positive pressure in a passage (4, 17, 26, 34) for purging the downstream pipe when the plug is at the second depth. In a variant embodiment, the coupling includes an adapter that the latch is suitable for retaining.

Abstract: This connection comprises two elements, male and female, adapted to fit axially in each other, the body of the female element being equipped with a lock mounted to slide and pierced with at least one opening for the fit of the male element. The wall of this opening is equipped with at least one element in relief adapted to cooperate with a corresponding element in relief of the male element in order to retain these elements in fitted configuration. The lock is in two parts and comprises a first part on which may be exerted, from outside the body, an effort of displacement, as well as a second part mobile with respect to the first part and bearing the aforementioned element in relief. A safety member is adapted to block the first part against the effort of displacement, without preventing the displacement of the element in relief with respect to the first part of the connection.

Abstract: The invention concerns a coupling comprising a male element (3) and a female element (5) adapted to be axially fitted and interlocked one inside the other. A locking mechanism (37, 55) axially immobilizes the male element in a coupling position and a temporarily retaining mechanism (37, 55, 59) immobilizes the male element, after its release by the locking mechanism, in a position for flushing the pipe (C1) connected to the male element. The locking mechanism is controlled by a maneuvering sleeve (53) sliding around a body of the female element. When it retains the male element in flushing position, the temporarily retaining mechanism is subjected to a first load (E1) derived from the pressure (P) of the fluid flowing (F) from the male element outwards and to a second load (E2), opposite to the first, exerted by elastic return means (57) which, when the pressure (P) reaches a safety threshold, moves the mechanism into a configuration releasing the male element.

Abstract: A female element of a quick connection provided with a closure valve, wherein the opening of the valve is controlled by a reaction force exerted by an O-ring disposed in an inner housing of a body of a male connection element adapted to be fitted in the female element. The reaction force results from the abutment of the valve on the O-ring when the male and female elements are coupled together. Upon the failure of the O-ring, the valve is not displaced so that the risks of leakages are eliminated.
