摘要： The present invention concerns a rotatable coupling (60) for connecting pipes, comprising a first hollow female clement (61) suited to be connected, for example, to a first pipe portion (51) or to a pipe fitting (202) and a second tubular male element (6) with a first end portion at least partially housed inside the first female element (61) so as to define a common inner space for the passage of a fluid, and with a second end portion suited to be connected to a second pipe portion (52). Said first element and said second element (61, 6) are suited to be rotated with respect to each other and respectively comprise a first abutment surface (1S) and a second abutment surface (6S) adjacent to the first abutment surface (1S). A first elastic annular sealing element (B1) is interposed between the first abutment surface and the second abutment surface (1S, 6S). The first abutment surface and the second abutment surface (1S, 6S) are placed at a mutual distance from each other so as to define an interspace (I) and the surface areas of the portions of the external surface of the elastic sealing element (B1) respectively in contact with the first and with the second abutment surface (1S, 6S) are minimal in the absence of a fluid and increase when the elastic sealing element (B1) is subjected to pressure exerted by a fluid inside the interspace (I).

Said first and said second element (61, 6) can be rotated with respect to each other, said second tubular male element (6) comprising a first abutment surface (6S). Furthermore, the rotatable coupling (60) comprises a third hollow tubutar element (12) housed inside the first female element and provided with a second abutment surface (1S) substantially opposite the first abutment surface (6S) so as to define a first interspace (I), and the third tubular hollow element (12) can be translated along a direction substantially orthogonal to the first and the second abutment surface (6S, 1S) between a closed configuration, in which the first and the second abutment surface (6S, 1S) are positioned at a minimal mutual distance, and an open configuration, in which the first and the second abutment surface (6S, 1S) are positioned at a distance that exceeds said minimal mutual distance.
