A fluid coupling (R) comprising a male element (A) and a female element, a ring delimiting an inner channel of the female element (B), and a piston slidably mounted with respect to the ring () between a closed position and an open position of the inner channel. Between a disconnected configuration of the coupling and the connected configuration, the ring is moved rotationally with respect to the female body and the ring is held longitudinally in the female body, the piston is moved longitudinally from its closed position to its open position. The male body comprises an outer body and an inner body, the inner body delimiting an inner duct of the male element (A). During connecting, the outer body and the ring are rotationally fixed around the central longitudinal axis. In the connected configuration, the outer body and the ring are rotationally fixed. During connecting and in the connected configuration, the outer body and the inner body are free to rotate but unable to move in translation. The female element (B) comprises at least one locking device () movable between a position locking the rotation of the ring, and a release position, and in the disconnected configuration, the locking device () does not prevent the rotation of the ring.

Fluid coupling

This coupling (R) includes a male element (A) including a male body () provided with a locking relief (), a purging ring () movable between a rear position, in which the purging ring closes off a purging passage of the male body, and a forward position, and a female element (B) including a female body (), a ball-retainer () carrying locking balls () of the male body, in a housing between a first position, in which they are able to oppose the removal of the locking relief, and a second position, in which the locking balls allow the removal of the locking relief, a valve body () secured to the ball-retainer, including coupling balls () suitable for securing the valve body and the female body in translation, an inner ring () suitable, in a retaining position, for keeping the valve body and the female body coupled by the coupling balls when the female element is uncoupled from the male element. In a first coupling configuration, the locking balls have crossed the locking relief of the male element; in a second coupling configuration, the inner ring has reached a position in which it no longer keeps the valve body and the female body coupled by the coupling balls; in a third coupling configuration, the female body keeps the locking balls in their first position; and in a fourth coupling configuration, the valve body has reached a position that allows fluid to pass between the two conduits. The female element includes steering means () able to drive the purging ring toward its forward position during the uncoupling.
