Abstract: This female element of a quick connector that connects to a male element and has a hollow body, which extends along an insertion axis and which delimits a receiving volume for the male element. Radial openings, formed in the body along a radial axis, open into the receiving volume. Each radial opening receives a latch, translatable in relation to the body along the corresponding radial axis, between a locked and an unlocked position. The female element has an actuating ring arranged about the body and translatable between a locked and an unlocked position. The ring has guide grooves, which interact with pins of each latch. The guide grooves associated with each latch are geometrically carried by a guide plane inclined in relation to the insertion axis so that each latch is driven between its locked and unlocked positions when the actuating ring is moved between its locked and unlocked positions.

Abstract: Male or female fluid coupling element and fluid coupling including such an element This coupling element has a body and a nozzle. The body delimits a housing for partially receiving the nozzle. The nozzle has a tubular part and a flange received in the housing. Two sealing barriers formed by at least one sealing joint are interposed between a rear surface of the flange and a front face of the body, between a front surface of the flange and a rear face of the body, respectively. A plug caps an inner conduit. Portions of the inner conduit communicate through at least one passage opening into an inner volume of the nozzle, forward of the plug, and on an outer peripheral surface of the flange. An inner chamber is separated from the inner conduit by the body, the flange, the plug and the first sealing barrier.

Abstract: This fluidic coupling (R) comprises a male element (A) comprising a male body (2), a valve (20) and a spring (24) pushing the valve (20) back toward its closed position, and a female element (B) having a sealing gasket (35), a piston (38), a slide valve (34) mounted around the piston (38) between a closed position, in which the sealing gasket (35) cooperates with the slide valve (34) and the slide valve (34) cooperates sealably with the piston (38), and a retracted open position. In a coupling phase, the male body (2) pushes the slide valve (34) back toward its open position and the piston (38) pushes the valve (20) back toward its open position. The piston (38) is mounted with the possibility of movement between a rear position and a forward position. The female element (B) comprises a lever (42) for converting the movement of the slide valve (34) into movement of the piston (38). During the coupling, from the closed position of the slide valve (34) to an offset position of the slide valve (34), in which the male body (2) cooperates with the sealing gasket (35) of the female body (26), the lever (42) is disengaged from the slide valve (34) and/or the piston (38), and the piston (38) is in the rear position. From the offset position of the slide valve (34) to the open position of the slide valve (34), the lever (42) is engaged with the slide valve (34) and with the piston (38), and moves the piston (38) toward its forward position. In the coupled configuration, the piston (38) is in its forward position and extends partially in the male body (2), a fluid passage being formed around the piston (38).

Abstract: A connector element (1), for a quick connect coupling to a terminal (3) having an interface (33) with a cylindrical enclosure, the connector element with a body delimiting an inner passage (43) for the fluid. In order for the connector to be able to be coupled reliably with terminals of variable dimensions and interface quality, the invention provides that the body has a conical portion (45) and that the connector element (1) has a movable bush (5), an elastic return member (8), which applies an elastic return force (F8) on the bush (5), and clamping pads (6) received in a respective housing (51) of the bush (5), the clamping pads being translated radially relative to the bush by mechanical cooperation with the conical portion, between a radial withdrawn position and a radial clamping position, to cooperate mechanically with the interface.

Abstract: This fluid coupling (R) comprises a female element (A) and a male element (B) able to be inserted into the female element, the female element comprising a main body (2) that defines a main inner channel (24), a plunger (64) and a slide valve (10), movable longitudinally in the main inner channel around the plunger between a closed configuration and an open configuration of the main inner channel. The male element comprises a complementary body (30) defining a complementary inner channel (302) and a valve (304) movable in the complementary inner channel between a closed off position and a separated position. In an uncoupled configuration of the fluid coupling, the slide valve is in the closed configuration and cooperates radially tightly with the main body and the valve is in the closed position. In a coupled configuration of the fluid coupling, the valve is pushed back in the separated position by the plunger and the complementary body cooperates with the slide valve. According to the invention, the slide valve comprises an outer slide valve (102) and an inner slide valve (104), which are movable relative to one another. In the closed configuration, the outer slide valve is in a forward position and the inner slide valve is in a forward position in which it is in tight contact with the outer slide valve and with the plunger. In the open configuration, the outer slide valve is in a withdrawn position and the inner slide valve is in an offset position relative to the outer slide valve. The female element comprises at least one gear reduction member (20). During a coupling phase, the gear reduction member (20) is disengaged from at least one among a front stop surface (63) arranged on the main body, a rear stop surface (124) arranged on the outer slide valve and a front stop surface (126) arranged on the inner slide valve. From the intermediate position to the withdrawn position of the outer slide valve, the gear reduction member is engaged with the front stop surface of the main body, with the rear stop surface of the outer slide valve and with the front stop surface of the inner slide valve, each gear reduction member moving the inner slide valve toward its position.
