Abstract: A faucet for pipe connection designed to be incorporated in a receiving structure such as a pipe or tank, includes a cylindrical body inside which is housed in concentric manner a sleeve defining the fluid communication channel and bearing at its outer end, articulated in rotation, a spherical closure element having a diametrical bore, a cylindrical ring, enclosing the sleeve and the spherical closure element, being housed so as to be capable of being driven in translation in the cylindrical body countering the effect of elastic return elements, the strokes in translation of the ring in the body driving in rotation the spherical closure element between an opening position wherein its bore is brought to coincide with the fluid communication channel and its closing position. The sleeve and the cylindrical ring of the faucet are mounted oscillating in the body of the faucet.

Abstract: A fluid coupling device has a male section (20) and a female section (21). Each of the sections has two rotatable ball valve elements (30,31). A docking member (23,24) is mounted on each section to accomodate a misalignment of the flow passageways when the sections are brought together. When the sections are brought together, the ball valves automatically rotate sequentially from flow-preventing positions to flow-permitting positions.

Abstract: A fluid coupling device has a male section (20) and a female section (21). Each of the sections has two rotatable ball-valve elements (30,31). A docking member (23,24) is mounted on each section to accommodate a misalignment of the flow passageways when the sections are brought together. When the sections are joined together, the ball valves automatically rotate sequentially from flow-preventing positions to flow-permitting positions.

Abstract: The present invention relates to a fast connection with radially acting bolt-locking having a groove in the male element and a bolt in the female element that can receive an axial displacement and whose rear flank when locking engages in the groove of the male element, the bolt being urged into locking by a spring. According to the invention, at least two balls mounted with free radial play in the body of the female element are interposed between at least two points on the perimeter of the bolt symmetrical to the axis of thrust of the spring and a longitudinal ramp embodied on the inner surface of a sliding ring. The invention is applicable to fast connections for piping.

Abstract: A fluid coupling device have separable male and female sections. Each section has a ball valve mounted for rotational and axial movement relative to a housing. When the sections are joined together, each ball valve rotates automatically to a flow-permitting position. When the sections are separated, each ball valve rotates automatically to a flow-preventing position. The ball valves interfit with one another so that a minimum volume of fluid is lost when the sections are separated.

Abstract: A coupling device has a male section selectively insertable into a female section. At least one of the sections has a ball valve rotatably mounted within a housing. When one section is inserted into the other, the ball valve is constrained to rotate about an axis eccentric to the center of the ball from a flow-preventing position to a flow-permitting position.

Abstract: A coupling with a rotating ball type valve which comprises a fixed axial shaft placed at the inner end of the body of a coupling connector, directed toward the outlet of the connector and bored to the diameter of the passage of the coupling, the shaft being formed at its end adjacent the inner end of the body with a support surface for a return spring and, at its other end, with a radial flange the two side faces of which are tangent to the outer surface of the shaft, a chamber opening into the spherical shaped sector opposite the passage-closing sector being provided in a spherical closure element, said chamber comprising surfaces cooperating in a sliding contact with the side faces of the flange of the shaft and the axis for driving in rotation the closure element being carried by the flange of the shaft and perpendicular to the flange faces.

Abstract: A coupling for flexible conduits in which the female element is constituted by a body 1 provided with an axial bore comprising internally a locking recess 2 and the male element is constituted by a tip on which is mounted a locking device constituted by an engagement element radially displaceable to engage in the locking recess of the female element under the action of a locking control device 13 constituted by a sleeve mounted longitudinally movably on the cylindrical central body of the male element, the end of said sleeve directed toward the engagement end of the male element forming a cam surface 14 coacting with the engagement element so as to displace it radially outwardly and this sleeve being resiliently urged by a spring 17 toward the locking position.
