Drain valve for cisterns

The innovation concerns a drain valve for cisterns with a according to the overlift principle working closure body, which is preferably is designed as a U-shaped bent tube, the ends of which are directed downwards, one end with the one in the cistern provided valve seat cooperates, while the other end is open at the bottom.

In the cisterns equipped with such drain valves So far, the amount of flushing water depends exclusively on the amount of water in the box and this amount in turn depends on the setting of the Float valve dependent. Jedoca is now used in cisterns In recent times, inlet valves float with tilting, which have considerable advantages over known float valves, however Allow no or only a very limited regulation of the filling volume of the cistern, «. In addition, the closure is very noisy .

The present innovation is therefore essentially the The object of the invention is to design a drain valve of the type mentioned at the outset so that the amount of rinsing water that occurs when Activation of the drain valve for the flushing process is released and according to the applicable regulations depending on Art of the toilet bowl and the arrangement of the cistern should be 6 or 9 liters, in each case exactly on the respective The setpoint is adjustable and the valve closes with as little noise as possible.

* The solution to this problem is, according to the innovation, f that the closing body of the drain valve has at least one lateral hole at a certain distance from its suction opening. To achieve the quietest possible completion of the flushing process, several holes are preferably provided at different distances from the suction opening, which are then closed according to the amount of flush water required in each case is releasably arranged on the closing body of the valve.

In the drawing is an embodiment of the innovation Shown., namely the figure shows a cistern equipped with the novel drain valve in a front view with a partially cut away front wall.

In the bottom of the cistern, a valve seat is attached in the usual Veise, to which the leading to a sink Drain pipe connects. The AbsehlußkSrper the cistern valve consists in the illustrated embodiment a U-shaped bent Eohr i, the ends of which are directed downwards, one end cooperating with the valve seat, while the other end 2 is open at the bottom and when it is closed Valve has a certain distance from the cistern floor.

I ft * · · ·

To open the valve, a two-armed actuating lever 5 is provided in a manner known per se, one era of which engages the tubular Abacl & luBkSsper Λ asKrip »When the lever 5 is briefly actuated, the closing body 1 is lifted from the valve seat and the flushing process is initiated. The effluent through the flushing pipe Vasserstrang generated in final body 1 has a suction effect, so that the contents of the cistern after the transfer jack principle through the open · lower end 2 of the body 1 is sucked and only for a relatively small amount of residual water in the cistern remains.

To now. To be able to interrupt the mentioned suction prematurely with little noise, are after the hiring over the suction end of the closing body 1 in its wall several in a row stacked holes 3 are provided, of which the lower three holes in the illustrated embodiment open., the rest, however, closed by a molded piece 4 are, which can be released by means of a pin in the larger hole 3 ' is arranged on the closing body 1. They each have open holes

s 3 cause air to enter the interior of the closure body 1 as soon as the water level in the box is up to the level of the

f open holes has sunk, and with it a tearing off of the through the open end of the body 1 sucked water strand.

Because several holes 3 are arranged one above the other, the air supply to interrupt the Überhebuiig takes place gradually. Since this avoids a sudden interruption, the valve works quietly.
