Abstract
Description
technical field
[0001] The invention relates to a drain valve for sanitary flushing tanks, in particular for concealed flushing tanks, having a valve housing and a valve body guided in the valve housing and formed as an overflow pipe, the valve body has a corresponding valve seat A sealing element, wherein the valve body is provided with at least one pulling piece for raising the valve body and a floating body. Furthermore, the invention relates to a sanitary flushing tank, preferably in the form of a concealed flushing tank, with a rear wall, a front wall and a drain valve, wherein an access opening for installing and removing the drain valve is formed in the upper section of the front wall . Background technique
[0002] Drain valves of the above-mentioned type have been known for a long time in various designs. In order to operate the drain valve reliably, it must be oriented and fixed substantially vertically in the flush tank. To secure the drain valve of a conventio...

Embodiment Construction
[0026] The figures of the figures show a drain valve 1 which can be installed in a sanitary cistern, in particular in a concealed cistern. The drain valve 1 is preferably designed as a dual-displacement drain valve, ie a larger flush volume for so-called full flushes or a smaller flush water volume for so-called partial flushes can be selectively delivered by means of the drain valve. For operating the drain valve 1 , an operating device (not shown) is arranged in the upper region of the tank. The operating device has two operating elements that can be controlled independently of one another. By way of example, the operating elements are implemented as movably mounted pushbuttons, wherein each pushbutton is assigned a lifting mechanism (not shown). The respective lifting mechanism is coupled to one of the two pull tabs 2, 3 of the drain valve 1, which has at its upper end an elongated lug 2.1, 3.1 in which the lifting mechanism engages.
[0027] The drain valve 1 has a subst...
