Abstract

215,794. Huebner, H. May 11, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Sprinkling apparatus.-A gas outlet valve for fire-extinguishing apparatus using gas as the extinguishing medium is operated by a differential piston having a small space between it or its casing to connect the pressure on the two s'des. If there is a fall of pressure on the upper, larger side of the piston m due to the fusing of a closure or the opening of a hand-operated valve in a pipe network connected to a channel h, the pressure below the piston being unable to escape sufficiently quickly between the piston and its casing, forces the piston up, thus raising a valve b in the gas passage a, c. To restore the piston and valve to its closed position and to fill the pipe network gas is introduced through a valve k.
