The quick acting male coupling for conveying fluids comprising a longitudinal valve body (1) having, along its longitudinal axis (2), an open cavity (3), a shutter (4) that is axially mobile in the cavity (3) of the valve body (1) in opposition to and by action of a helical spring (5) and that can be positioned against a valve seat (6) for closure of the passage of fluid through the cavity (3) of the valve body (1), and a guide element (7) for the shutter (4), pressed by the helical spring (5) against a mechanical stop (8), the shutter (4) comprising an axially hollow rod (9), the guide element (7) comprising a base (1 1), a guide pin (12) that axially extends out from the base (1 1 ), and a plurality of fins (13) for centring the guide element (7) which circumscribe the guide pin ( 12) and extend out from the base ( 1 1 ) on the same side as the guide pin (12), the rod (9) being fitted on the guide pin (12) with the interposition of the helical spring (5), which is inserted in the cavity of the rod (9) and fitted on the guide pin (12). |
