DE2917904A1 - Lavatory cistern water economy system - has single outflow valve for continuously adjustable water discharge volume - Google Patents

Abstract

The device may be fitted on every type of water closet, witt only one variously controllable outflow valve. It provides economy in water use on a flushing cistern as in 2915581. Ejection of water is allowed to take place by operating of knobs, and opening and closing of an outflow valve for variously set max. and min. volumes of water. Discharge is continuously adjustable, as required. There can be a bottom float providing large volume discharge, and interchangeable top float for various smaller discharges.

Description of additional patent application with its own character 002 - Me

to patent application P 29 15 581.5 from April 18, 1979 with its own mark oo1 - Me from April 13, 79 Title: Toilet cistern with water-saving system with only one different controllable outlet valve Area of application: see P 29 15 581.5 Purpose: see P 29 15 581.5 State of the art: see P 29 15 581.5 including the technical solution there Criticism of the state of the art: see P 29 15 581.5. The technical solution takes place there through two valves. This is expensive to construct and may require repairs.

Task: see P 29 15 581.5 with the additional task, the technical one Simplify solution.

Solution: According to the invention, the object is described as in P 29 15 581.5 released: via the economy button (A), the full flush button (B) and the stop button (C) the water output can be continuously regulated.

In contrast to P 29 15 581.5, there is only one outlet valve Used with two floats: When the economy button (A) is pressed, the valve is raised (V) in the liner (L) only so far that the knob (N1) through the upper float (S1) is blocked and therefore closing of the valve is only possible when the water level has dropped by approx. 3, 4 or 5 1 depending on the size of the swimmer (51-3, -4, -5) is. The lower float (52) does not block. It only blocks when actuated the full flush button (B) with a larger stroke than the economy button through the lower knob (N2) the valve (V) with the seal (D), so that in this case approx. 10 1 run out (shown in dashed lines in Fig. 1).

In both cases, the water outflows directly through the drain (AWAY).

As in P 29 15 581.5, the stop button (C) enables a stop at any time Interruption of the rinsing process.

achievable advantages: Compared to P 29 15 581.5 is the technical solution easier by using only one outlet valve, i.e. cheaper to be constructed and not so susceptible to repairs.

The floats for 3, 4 or 5 l water output are problem-free to replace.

Description of the embodiment: An embodiment of the The invention is shown schematically in FIG. 1 without a scale.

The symbols mean: A = economy button, B = full flush button, C = stop button, L = Liner, N1 and N2 = knobs, S1-3 to 5 = float for approx.

3 to 5 1, S2 = float for approx. 10 1, V = drain valve, AB = drain and SB = cistern floor.

Claims to additional patent application with own character 002 - Me to patent application P 29 15 581.5 from 1-8.4. 1979 with own sign oo1 - Me from 13.4. 1979 Generic term: toilet cistern with water-saving system suitable for use on each toilet with just one different controllable outlet valve Part: characterized in that the water ejection through the operation of keys and the opening and closing of an outlet valve in differently definable maximums and minimal amounts of water can be done and the water output depending on requirements is infinitely variable. Generic term of the 1st subclaim: 2nd toilet cistern with water-saving system according to claim 1 with only one outlet valve and two floats, the above lying float differently dimensioned is exchangeable. Characteristic part: characterized in that the lower-float The water output of approx. 10 1 is guaranteed, the upper one is exchangeable depending on the dimensions a water output of approx. 3, 4 or 5 1.
