Patent ID: 11346482

Abstract:
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 (28) 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 (45) movable between a position locking the rotation of the ring, and a release position, and in the disconnected configuration, the locking device (45) does not prevent the rotation of the ring.
