Abstract: The female element of a quick connection according to the invention is provided with a closure valve, whose opening is controlled by an effort of reaction exerted by an O-ring disposed in an inner housing of the body of a male connection element adapted to be fitted in this female element, this effort resulting from the abutment of the valve on the O-ring further to the male and female elements being coupled together. In the absence of O-ring, the valve is not displaced and obturates the inner conduit of the female element, this limiting the risks of leakages.

Abstract: A quick connect coupling for removably connecting two pipes which comprises a male element adapted to fit into a female element along a principal axis of the coupling. The Female element includes at least one ramp for receiving a radial projection of the male element to lock these elements together. The ramp is formed in a ring freely rotatably mounted in the female element, and fixed in translation along the principal axis, while the projection is fixed with respect to the male element. The ramp forms a seat for locking the radial projection. Locking is obtained by essentially axial movements of the male and female elements with respect to one another.

Abstract: This female element in a secured quick connection intended for removably joining pipes of fluid under pressure, is adapted to receive a male element, fitted therein along a longitudinal axis. It is equipped with means for locking the male element in fitted configuration which comprise at least one elongated member, mobile in translation parallel to an axis which is oblique with respect to the axis of fit of the male and female elements and provided with a cylindrical part of which one end is intended to be engaged in a peripheral groove of a male element. This end is partially defined by a surface for abutment against a side of the groove. This member is also provided with a tab which projects radially with respect to the body of the female element and which cooperates with a control ring.

Abstract: Linearly actuated quick connect pipe couplings which include a male element and a female element adapted to fit into each other along a principal axis. One of the elements includes at least one ramp for receiving a radial projection mounted to the other element which locks the elements together by axial movement of the elements relative to one another. One of the ramp or the projection is formed with a ring mounted to rotate but is fixed in translation along the principal axis of one of the male or female elements. The ramp forms a first seat for locking the projection when the coupling is in a configuration to permit fluid passage and a second seat, offset axially with respect to the first seat, for locking the projection when the coupling is in a configuration to permit decompression of fluid within the coupling.

Abstract: The present invention relates to a quick connection for the removable join of two pipes, which comprises a male element and a female element adapted to fit into each other along a principal axis of the connection, the female element comprising at least one ramp for receiving a radially projecting part of the male element with a view to locking these elements when the connection is in configuration of passage.

Abstract: A quick safety connection for the removable joining of pipes, comprising a male connector and a female element adapted to fit and to be locked inside one another. A controlled locking mechanism is adapted to immobilized the male connector axially in a position of connection, while at least one retention member is provided to immobilize the male connector, after release of the connector by said locking mechanism, in an intermediate position of discharge of the pipe connection. The locking mechanism and retention member are controlled by a sleeve sliding around the female element. Vents and safety stops are provided to limit the movement of the sleeve under the effect of the pressure prevailing due to the discharge of the connection in the intermediate position between the female element and the sleeve.

Abstract: Safety circuit breaker for a pressurized fluid handling installation wherein the circuit breaker includes a male element and a female element which are adapted to be connected axially with respect to one another such that, when assembled, the male element is connected to a sleeve mounted within the female element. Movement of the male element to a position of unlocking relative to the female element causes the internal sleeve to move from a first position to a second position wherein at least one orifice within the female element is blocked to prevent fluid flow therethrough. The at least one orifice is directed radially relative to the axis of the male and female element such that pressure against the sleeve is radial and not axial. A locking of the male element relative to the female element is created by balls which are carried by a slide which is elastically urged so as to force the balls into a groove in the male element.
