Valves closing after predetermined flow.- A seat-action water-closet flushing-valve for use on board ship, railway trains, stations, &c., comprises a double-sided valve A operating between oppositely-disposed seatings 8, 9 on the inlet pipe 1 and the discharge pipe 2, respectively. The valve is operated from the closet seat 14 through a lever 19, rotary way-shaft 13, external link and arm 21, 22 and internal arm 12. The amount of the flush, which passes during the time the valve is moving from the upper to the lower seating, is regulated by a dash-pot comprising an air-cylinder 23 connected to the lever 19, a stationary plunger 25 mounted in a suspended bracket 37, and a weight 27. The timing can be regulated by an adjustable air-escape screw 28. The valve A may be replaced by a double-beat or equilibrium valve having a hollow stem, or a solid stem with a lateral discharge passage formed in the valve casing.
