Abstract

505,411. Flushing - valves. DREYER, F.W.A. Sept. 7, 1938, No. 26176. [Class 135] A flushing-valve comprising a pilot valve and a main valve on concentric spindles has a dashpot provided with a discharge opening which is adjustable from the outside and controls the closing of the main valve. To assist opening, water pressure on main valve 22 is first balanced by the admission of water to cylinder 20 through pilot valve 16 and channel 18. Upon release, water pressure closes both valves, the closure of the main valve being delayed by the water in cylinder 20 leaking slowly through the adjustable discharge opening 24.
