ABSTRACT:
Quick-action male coupling (1) connectable under pressure and having a tubular outer body (2) containing a valve guide (7) supported so as to be central and defining flow channels (FC) for the fluid, and an inner valve (9) which is selectively pushed so as to tend to close the mouth (8) of the outer body (2), wherein a sliding tubular body (20) is present between the outer body (2) and the valve guide (7); the sliding tubular body (20) is pushed by a spring so as to tend to close the flow channels (FC); in the closed position the sliding tubular body (20) is in sealing contact with the outer body (2) and with the valve guide (7) and experiences hydrostatic pressures of equal magnitudes but opposite directions exerted by the fluid; and the sliding tubular body (20) is pushed by the inner valve (9) so as to tend to open the flow channels (FC).
