Suomi-Finland (FI) - (72) Einar Rosenqvist, Esbo, Ingmar · Ström, Helsingfors, Finland-Finland (Fl) (5M Water flush flush valve - Spolventil för vattenklosett

The invention relates to a flushing valve to be placed inside the flushing tank of a water closet, comprising a valve housing inside which is a valve stem, an auxiliary piston acting to close the valve and a valve body closing the valve opening.

In similar known flush valves, it has not been possible to adjust the closing of the valve after the manufacture of the valve. Only in old-fashioned flushing devices based on the patch effect, a kind of flushing water volume control has been implemented by means of air holes, but these known solutions cannot be applied to modern flushing valves. If the exact conditions (size, shape, etc. of the tank) in which the valve operates are known in advance, this possibility of adjustment is not essential. Instead, an adjustment option is needed if the valve is to be sold separately and fitted to tanks of different sizes and / or shapes, or if the valve is to be sold abroad, in which case regulations on the amount of water to be used for rinsing may vary. When the amount of water required is smaller than usual, it is most advantageous to adjust the closing of the valve so that the height of the water surface remaining in the tank after rinsing increases. The potential energy of a higher amount of rinsing water is then utilized to enhance rinsing.

The object of the invention is to provide a flushing valve, the closing of which can be adjusted as described above and thus to determine in each case the height of the water surface remaining in the flushing tank. The invention is characterized in that a control opening or control openings are made in the wall of the valve housing or in connection with installation through which the flushing water tank communicates with the space inside the valve housing and above said auxiliary piston. A valve type with said adjustment option can be adapted to different toilets. The adjustment hole itself is placed in the vertical direction at approximately that height. To which it is desired After rinsing the water surface of the rinsing water tank after residual rinsing. I did so because the lowering of the water level in the rinsing water tank directly determines that moment. Allowing air to enter the chamber supporting the valve body And thus causing the valve to close. However, without entering the chamber, there is a small time delay before the water in the chamber is reduced enough for the valve to close. For this reason, the water level of the tank is practically slightly below the upper edge of said adjustment opening.

Since the location of the upper edge of the control opening is crucial for the closing of the valve, the valve can be equipped with a device. With which the position of the upper edge of the adjustment opening can be determined vertically. One possibility is to arrange the adjusting member in the adjustment opening itself. Allows the top of the weather vent to be moved. Another way is to arrange adjustment openings at different heights in the valve housing. From which the opening at the desired height is selected by covering the adjustment openings above it. A selector plate rotating around the valve housing can be suitably used for this purpose. With which you can select an adjustment hole at the desired height. In addition, one way is to arrange the indications of the holes in the wall of the valve housing at different heights without opening them. In this case, the hole designation at the desired height can be easily opened as an adjustment opening during installation.

The invention will now be described in more detail with reference to the accompanying drawings, in which - Fig. 1 shows an embodiment of the invention in longitudinal section, - Fig. 2 shows point A-A of the embodiment of Fig. 1 in a front view, and - a side view of another embodiment of the invention.

In the drawings 1 denotes a valve housing, 2 valve stems and 3 auxiliary pistons, which together with the valve housing delimits the chamber 6. Further 4 denotes a valve body which prevents water flow from the flushing tank through the opening 7 into the valve opening 5. In addition And 10 indicates the top of the adjustment hole. In Fig. 3, in turn, 11 illustrate the adjustment apertures, 12 the adjustment aperture selection plate, and 13 the mute apertures in the selection plate.

The operation of the valve is based on the fact that when the valve stem 2 is lifted by means of a knob 14 or similar, water can flow unimpeded from to fall And the vent-brick opening closes. The auxiliary piston 3 el falls before otherwise a vacuum 6 would build up in the chamber 6. Thus, the earlier the air enters the chamber 6, the earlier the valve closes And the higher the water level remains in the flushing tank. The air supply can be directly influenced by moving the upper edge 10 of the control opening, which can be done e.g. by means of the control element 9 (Fig. 1 and 2) or by providing the valve housing with control openings 11 at different heights (Fig. 3) # From the openings 13 in the selection plate 12 height adjustment aperture.

The invention is not limited to the embodiments shown, but several variations thereof are conceivable within the scope of the appended claims.

Claims (7)
