Abstract

15,479. Turnbull, W. July 3. Valves closing after predetermined interval or flow. - A flushing- valve for water-closets &c., of the pistonoperated type started by an auxiliary push starting-valve for discharging a certain quantity of water at each operation, is provided with means for preventing a second full flush of water from being obtained before a certain definite interval of time has elapsed. A bellshaped plunger 12 is disposed within a dep e n d i n g sleeve 30 carried by a flange 16 and secured by the top cap 19. A partition across the sleeve is perforated at 22, and is formed with the valve seat 25 of the starting-valve 24. The main operating- piston 5 is cup-shaped, and has a passage 11 from the inlet 3 to the back thereof controlled by a slit screw 9. The lower end of the plunger where it rests on the piston 5 is serrated, the sleeve 30 is fitted with an adjustable slit screw 31 to allow pressure water to pass to the spaces above the piston and within the sleeve 30. On the opening of the main valve by the operation of the starting-valve 24, 29, the plunger 12 is carried up by the piston 5 until it abuts on and closes the starting-valve, and is maintained in this upper position by fluid pressure until the main valve has closed again. The plunger 12 then gradually subsides and rests finally upon the piston 5, whereupon the apparatus is ready for the next full flush.
