An adjustable valve to control the amount of water flowing through the refill water hose to the overflow tube and into the water closet bowl. The valve is a dual component device including a housing structure and a lever component. Both the housing structure and lever component have a trunk section of similar shape, but of different size. The trunk section of the lever component fits snugly within the trunk section of the housing structure. The lever component is able to rotate within the housing structure. The trunk sections in both the housing structure and the lever component include openings which provide a passageway for water to flow therethrough. The openings in the housing structure are spherically shaped and the openings in the lever component are pear-shaped. The housing structure includes a pair of tabs disposed 90° from one another for limiting the rotation of the lever component such that the openings in both the housing structure and lever component are always aligned. As the lever component is rotated within the housing structure, the flow of water is varied. The water flow becomes more restricted as the lever component is rotated from one tab to the other, but is never completely obstructed.

Soupape réglable servant à équilibrer la quantité d'eau passant par un tuyau de remplissage d'eau pour s'écouler vers un tuyau de trop-plein et une cuvette de W.C.. Cette soupape comprend deux éléments : une enveloppe et un levier, qui sont constitués chacun d'une section principale de forme semblable, mais de taille différente. La section principale du levier s'ajuste exactement à la section principale de l'enveloppe, le levier étant en mesure de tourner à l'intérieur de l'enveloppe. Ces sections principales, de l'enveloppe et du levier, sont munies d'ouvertures par lesquelles l'eau peut s'écouler. Les ouvertures de l'enveloppe sont de forme sphérique; celles du levier sont en forme de poire. L'enveloppe possède une paire de languettes disposées à 90 degrés l'une par rapport à l'autre et servant à limiter le mouvement de rotation du levier de façon telle que les ouvertures de l'enveloppe et du levier soient toujours alignées les unes en face des autres. Lorsqu'on fait tourner le levier à l'intérieur de l'enveloppe, le niveau d'écoulement de l'eau varie. Cet écoulement, qui est moins restreint lorsqu'on fait tourner le levier d'une languette vers l'autre, n'est jamais complètement bloqué.
