Abstract

402,226. Stop valves. CARFAGNA, C., 26, Via della LibertÓ, Naples, Italy. Oct. 17, 1932, No. 28987. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 8, 1932.] [Class 135.] A water-supply valve has a cylindrical chamber 2 opening at its lower end into an inlet pipe 1 and at its upper end into an outlet pipe o. Vertical grooves 6 are formed in the side of the chamber for the passage of water. A closure member 4 is adapted to be forced upon its seat by a screw-handle 8 which is not connected to it. If, when the valve is open, negative pressure should occur in the pipe 1, the member 4 will fall and close the opening automatically.
