A connector (1) for transferring a fluid or for applying a pneumatic pressure from an inlet conduit (2) to an outlet conduit (3) that may rotate with respect to the inlet conduit (2), in which the connector (1) comprises a rotating shaft (17) defining the outlet conduit (3) therein, which has an inlet opening (70), said rotating shaft (17) defining a rotational axis (S-S) and comprising a sealing disc (19) extending radially from said rotating shaft; an insertion chamber (5) to which said inlet conduit (2) is sealingly securable, said chamber leading towards said inlet opening (70) of the outlet conduit (3); at least one first cylinder-piston unit (100) comprising a cylinder (9) and a piston (21) slidable in said cylinder (9), said piston (21) having a sealing surface (22) facing the sealing disc (19), and said cylinder (9) being fluidically connected or connectable to said insertion chamber (5); said piston (21) being configured to be selectively actuated between a sealing position in which the sealing surface (22) is at a minimum distance or in contact with the sealing disc (19), in which a fluidic seal is carried out between said insertion chamber (5) and said inlet opening (70) of the outlet conduit (3) of the rotating shaft (17), and a non- sealing position in which the sealing surface (19) is moved away from the sealing disc (19), in which a fluidic seal is absent between said insertion chamber (5) and said inlet opening (70) of the rotating shaft of the outlet conduit (3) of the rotating shaft (17). |
