  • FIG. 8 is a fragmentary sectional view similar to FIG. 7 showing a portion of a further modified form of toilet flush valve.
  • the toilet flush valve 10 embodying the invention is adapted to be mounted on an inlet water pipe 11 extending upwardly within the tank 12 of the toilet which, in turn, is operatively connected with the toilet bowl 13.
  • the main toilet valve or ball 15 Upon manipulation of the handle 14, the main toilet valve or ball 15 is elevated to permit the water within the tank 16 to flush the toilet in accordance with well-known practice.
  • the tank 12 is provided with an overflow pipe 17 in accordance with conventional practice.
  • all the parts of the flush valve mechanism 10 are made of a non-corrosive material, such as the acetal resin known under the trade mark Delrin.
  • the main body of the flush valve 10 comprises :a first upper section 20, a second intermediate section 21 and a third lower section 22. Each of the sections is substantially identical in horizontal cross-section (FIG. 3). A flexible diaphragm 23 is interposed between the first section and the second section 21 and a sealing gasket 24 is interposed between the second section 21 and the third section 22. Sections 20, 21 and 22 are adapted to be clamped together by means of screws or rivets.
  • the upper section 20 is provided with a cavity 25 which defines a chamber above the 3,401,716 Patented Sept. 17, 1968 diaphragm 23.
  • the second section 21 is provided with an annular seat 26 that divides the area beneath the diaphragm 23 into an annular inlet chamber 27 and an outlet chamber 28.
  • the lower section 22 is threaded on the upper end of inlet pipe 11.
  • Inlet pipe 11 is aligned with an inlet opening 29 in second section 21.
  • Passage 30 in second section 21 and aligned passage 31 in first section 20 provide communication between inlet 29 and the chamber 25.
  • Outlet chamber 28 is connected by a vertical outlet 32 in second section 21 to a horizontal passage 33 (FIGS. 3 and 6) which, in turn, extends tangentially to an annular space 34 formed between the inside walls of aligned openings in the first section 20 and the second section 21 and a pipe 35 that extends upwardly from the third section within the first and second sections.
  • First section 20 is also provided with an opening 36 extending to the atmosphere.
  • a radial passage 37 extends laterally outwardly and is adapted to be connected by a pipe 38 (FIG. 1) to the overflow pipe 17.
  • the first section 20 is also provided with a second chamber 38 which is connected by a short passage 39 with chamber 25.
  • An interconnecting passageway 40 extends between chamber 38 and a passage 41a which communicates with the annular outlet space 34.
  • a resilient conical seat 41 of rubber or the like is provided at the upper end of the passageway 40 and a plastic ball 42 is adapted to be seated by gravity and the pressure of water against seat 41.
  • Ball 42 can be moved upwardly away from the seat 41 by a pin 43 formed on the upper end of an actuator 44 through which a float arm 45 extends.
  • Pin 43 extends through passage 40 and gasket 24 seals against the pin 43.
  • Arm 45 is pivoted to the lower section 21 at 46 and has an angularly adjustable float 47 on one end thereof. As shown in FIG. 4, when tank 12 is full of water, the water level L maintains float 47 and, in turn, the arm 45 in position to hold the actuator 44 and, in turn, the pin 43 downwardly permitting the water pressure in chamber 25 and chamber 38 to hold
  • the handle 14 on the tank 12 is operatively connected to a lever 48 pivoted to the lower section 22 of the toilet flush valve 10 at 49 (FIG. 2).
  • the lever 48 is moved upwardly as shown in FIG. 5 to move the actuator 44 and pin 43 upwardly and move the ball 42 away from the seat 41.
  • the float 47 moves the actuator 44 downwardly and finally permits the ball 42 tc be seated against the seat 41 and thereby interrupts the flow of water to the tank.
  • a drip opening 50 is provided in the lower section 21 between the outlet 33 and the exterior of the housing
  • the float arm 45 is provided at the end opposite the floa with a scoop 51 into which the water from the drip open ing 50 passes as the tank is being filled.
  • the weight 0 the float 47 is balanced with relation to the capacity 0 the scoop 51 such that after a predetermined period 0 time, when the water has substantially filled the scoo 51, the float arm 45 is moved in a counterclockwise fasl: ion to permit the ball 42 to seat against the seat 41, eve though the level of the water in the tank has not rise:
  • the differential pressure that would normally occur by a relative reduction pressure in the inlet opening 29 permits air to enter through the inlet 36 and pass to the inlet pipe 38 rather than water to be siphoned from the pipe 35. This thereby avoids siphoning of the contents of the tank.
  • a piece of elastic foam material 25 may form the upper wall of the chamber 25.
  • the float rises and the valve 42 is permitted to seat against the annular seat 41 the water pressure acting on the diaphragm 23 seats the diaphragm against the annular seat 26.
  • piece 25' of resilient foam material is partially compressed. As the diaphragm fully seats to the position shown in FIG. 6, the piece of foam material is fully compressed.
  • the yielding wall on the upper end of the chamber 25 can be formed by a sealed bag 60 of rubber having air entrapped in the interior space 61 thereof FIG. 7.
  • the wall 62 forming the top of the chamber 25 may be made of resilient material such as rubber and have spring 63 therea'bove which yieldingly urges the wall downwardly as shown in FIG. 8.
