Definitions

  • the invention refers to a WC cistern (fig. 1) consisting of the shell of an air vessel which meets requirements for strength as well as economy of space and aesthetics.
  • the cistern includes an airbag and its air valve, an injector with a non-return valve on its intake and an outlet valve leading to the toilet bowl.
  • the WC cistern (figure 1) with airbag and injector is comprised of the shell (1) which is cylindrical, spherical etc. in shape and conforms to materials strength requirements but can also be fitted in the space in an aesthetically pleasing manner.
  • the hole is large enough to allow the empty airbag to fill up with air when required.
  • the injector has a non-return valve for uptake of atmospheric air.
  • the water that flows in occupies the bottom part of the space, compressing the air which enters through the injector, as well as the air inside the air bag in the top part of the space.
  • the inflow of water will continue until the pressure of the compressed air is equal to the pressure of the water, which is 3-5 atmospheres.
  • the non-return valve (5) which lets air in through the injector is already closed, preventing water from flowing outward. The more air pressure we have in the airbag (2), the less water will enter, and vice versa.
  • the system's discharge valve (figures 2 and 3), fitted either on the air vessel (cistern) or on the outlet pipe, operates smoothly, in full harmony with the principles of operation of the system.
  • the valve (figures 2 and 3) consists of two plungers (1 and 2), fitted with rubber rings (3) to make them watertight.
  • the plungers are attached to a rod (4), at a suitable distance from each other.
  • the rod (4) protrudes above the cover (5) and is connected to a knob (6) to pull the rod (4) and the plungers (1 and 2), which are held down by a spring (7), so that the lower valve/plunger (2) rests in the base (8) which has been suitably formed at the bottom of the jacket (9) of the valves (fig. 2 and 3).
  • the jacket (9), at a suitable distance above the lower valve/plunger (2) and below the pressure equalising plunger (1) has slots (10) through which the water flows out towards the toilet bowl when the knob (6) is pulled, raising the rod (4) together with the plungers (1 and 2). Plunger (2) uncovers the outlet slots (10) and the water flows out into the bowl.
  • the valve operates in the following manner: When the cistern has emptied and is at zero pressure, the tension of the spring (7) pushes the rod (4) together with the plungers (1 and 2) downwards, and the valve/plunger (2) closes the outlet slots (10).
  • the cistern begins to fill with water from the pipe (11) and pressure gradually builds up in the space.
  • the pressure acts upon equal surfaces of the plungers (1 and 2) above and below, so that the force exerted on the knob (6) by the pressure is zero.
  • valves pictured in figs. 2 and 3 are of the same type, but the valve in fig. 2 can be incorporated in the system, whereas the valve in fig. 3 may be fitted to the outlet pipe in any position the user desires.
