Patent ID: 10054231

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 between the rotating shaft (17) and the structure, preventing a fluid to flow between the sealing surface (22) of the piston (21) and the sealing counter-surface of the disc (19); and a non-sealing position, in which the sealing surface (22) is moved away from the sealing counter-surface (34) of the disc (19) whereby a fluidic seal is absent between the rotating shaft (17) and the structure.
