<p>A water supply valve cartridge is provided to minimize surface friction of a rotational disc for regulating the flow rate with a fixed disc by minimizing the rotational disc. A valve cartridge includes rotational discs(130,150) opening and interrupting cold/hot water supply holes(121,122), an introduction hole(141), and water discharge holes(123,132,142,152) formed in fixed discs(120,140) while the rotational disc is rotated by manipulating regulation members(170,160). The rotational disc for discharging water by regulating the amount of hot and cold water introduced by manipulating the flow rate regulating member has a diameter interrupting only a portion in which a discharge hole of the fixed disc is formed. When the rotational disc is rotated, a pair of flow rate regulating recesses opening only the water discharge hole are formed on both sides of one surface.</p> |
