ES249077U - Tap valve for toilet tanks (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Faucet valves for toilet cisterns characterized essentially by the fact that the tap body comprising, provided with an externally threaded end for fixing to the body of the tank, forms at the end of the inlet passage an annular chamber around a concentric cylindrical duct, having a radial outlet for the drop of water at the bottom of the tank, with tubular extension to obtain a silent fall, and whose radial outlet is concentrically arranged to a tube also radially born from the body of the tap; with the particularity that the concentric cylindrical tube located in the annular chamber is closed at the end facing the water inlet and open at the opposite end, where the valve device acts, which comprises a closure cap of the body of the valve. Tap, coupled by pressure thread, whose plug has a micrometric, axial air outlet on the back, on which acts a lever-rocker closure with elastic joint, acting by buoy-float, while inside the plug receives in its hollow an axially moving part having in the direction of the concentric outlet of the water a spreader of a crosshead that guides it in its mouthpiece, whose movable piece is subject to the stopper by the arrangement of an elastic cap formed in several cylindrical sections of progressive diameter, the largest of which acts as a joint between the plug and the body of the tap and the smaller one has its base crossed by the spreader of the crosshead, actu this base is placed around the breakwater as a seal on the mouth of the concentric outlet of the tap, forming the stopper, moving part and cap, a deformable chamber that determines, in the opening position of the micrometric hole of the stopper, its understanding to allow free passage of the water to the filling tube of the cistern, while the level of this determines the closing of said hole by the rocker-lever allowing, through another micrometric hole provided in the flat base of the cap and moving part, to pass the water to the chamber of the plug, causing its distension until the passage of the water to the filling tube of the tank is eliminated, as the pressure in said chamber is greater than that of the feed water itself.
