Abstract

LOW NOISE TOILET TANK VALVE

ABSTRACT OF THE DISCLOSURE

A toilet refill valve is described for refilling a water closet after each flushing, which produces minimal noise during the refill process. The valve includes a valve device which can open to pass water to a vertical outlet tube that empties into the bottom of the water closet. An anti-siphon air tube near the top of the outlet tube has an upper end open to the atmosphere and a lower end facing downwardly along the outlet tube. A restriction in the outlet tube below the air tube, causes water to fill the outlet tube and at least the bottom of the air tube for a water inlet pressure of at least 20psi. The water at the bottom of the air tube prevents air from being dragged into the downwardly facing air tube, to avoid the noise that would result from such air flowing through the air tube and bubbling out of the bottom of the outlet tube.
