Abstract: A seal connector device (1) for achieving a temporary fluid-tight connection between a rotating shaft (17) rotatably connectable to a structure and said structure, wherein the seal connector device (1) comprises said rotating shaft (17) which defines a rotational axis (S-S); a sealing disc (19) extending radially from said rotating shaft (17); at least one first cylinder-piston assembly (100) comprising a cylinder (9) and a piston (21) slidable into said cylinder (9), said piston (21) having a sealing surface (22) facing the sealing disc (19), and the sealing disc (19) having a sealing counter-surface (34) facing the sealing surface (2), said sealing surface (22) being suitable for abutting against said sealing disc (19); said piston (21) being configured to be selectively operated between: a sealing position in which the sealing surface (22) of the piston (21) is at a minimum distance or in contact with the seal ing counter-surface (34) of the disc (19), in order to achieve a temporary fluid-tight connection

Abstract: 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 surfa
