Abstract:
Female fitting (1) for a pipe connection adapted to be carried by a receiving structure such as a pipe or gas tank, of the type comprising a cylindrical body (10) within which is disposed concentrically a sleeve (2) defining the fluid channel (C) and carrying at its external end, articulated in rotation, a spherical closure element (3) having a diametral bore (3a), a cylindrical ring (4), surrounding said sleeve (2) and the spherical closure element (3), being disposed drivably in translation in the cylindrical body (10) against the force of a resilient return means (7), the translatory movements of the ring (4) in the body (10, 80) driving in rotation the spherical closure element (3) between its open position in which its bore (3a) is brought into coincidence with the fluid channel (C) and its closed position, characterized in that the inner end of the sleeve (2) has a spherical bearing surface (2a) bearing against a complementary bearing surface (10a) of the inner end of the cylindrical body (10) of the female fitting as a swivel joint.
