Patent number: 6026857Abstract: A valve fitting comprises a female element and a male element. The elements are composed of fixed parts and axially sliding parts that, when at rest, arrange themselves in a closing position of a passage opening for fluid and in occurrence of the coupling between the two elements are displaced by their engagement with corresponding parts of the other element to an opening position of the passage opening. The male element includes a safety valve to intercept a fluid feed substantially at the end of the coupling manoeuvre of the two fitting elements. The male coupling member includes also a pressure relief valve interposed between the fluid feed and a pressure relief chamber.Type: GrantFiled: April 19, 1999Date of Patent: February 22, 2000Assignee: Stucchi s.r.l.Inventor: Giovanni Stucchi

Patent number: 5855227Abstract: A quick-coupling fitting for pipes comprises a female element and a male element that can be coupled together. The female element comprises parts that are fixed and parts that can slide between a closed position and an open position of a passage for fluids. The fixed parts comprise a stem having one end enlarged, and the slidable parts comprise a bush, coaxial with the stem, axially slidable and elastically urged towards the closed position. The bush defines with the stem a hollow space for the passage of the fluid. The bush is provided with a sharp-edged metal annular projection that, in the closed position, engages with a metal frustum-shaped surface of the enlarged end of the stem to provide a seal of said hollow space.Type: GrantFiled: May 21, 1996Date of Patent: January 5, 1999Assignee: Stucchi, s.r.l.Inventor: Giovanni Stucchi

Patent number: 5592970Abstract: A quick-coupling fitting for pipes comprises a female element and a male element that can be coupled together, formed by fixed parts and axially sliding parts. The fitting is provided with a valve apt for intercepting a communication port between a conduit and a passage port for the fluid in the initial stages of the coupling action and for opening it in the final stages of the coupling action. A seal of a fixed internal casing is covered by a sliding bush whatever is the axial position assumed by the bush during the initial and final stages of the coupling action.Type: GrantFiled: June 5, 1995Date of Patent: January 14, 1997Assignee: Stucchi s.r.l.Inventors: Giovanni Stucchi, Gianmarco Gatti
