摘要： Sealed coupling device for introducing a test fluid into a component (50) to be checked including a hollow body (1) defining a longitudinal axis (2), an elongate element (3) housed in the hollow body and defining an axial through hole (4) being part of conduits for the passage of said test fluid, and a resilient sealing element (6) which is annular shaped, is connected to the elongate element, and is adapted to be compressed between two axially movable surfaces (7, 19) under the thrust of a spring (12) and to radially expand to engage a surface (55) of the component to be checked. The surfaces compressing the resilient sealing element are displaced by an axial actuating mechanism with shaped surfaces (8d, 9b) which causes translation and rotation movements of the elongate element in order to alternatively move from an operative condition, in which the sealing element is compressed, to a non-operative condition defined by the contact between stationary (11d) and movable (9a) reference surfaces.
