Abstract:
1. A mixing valve device comprising: a housing including a chamber formed therein, and including an opening formed in an upper portion thereof and including a bottom portion, a cover attached to said bottom portion of said housing and including two inlet ports separated from each other for receiving cold water and hot water respectively, and including a first outlet port and a second outlet port formed therein, said cover including a conduit member formed therein and defined by two first peripheral conduit segments and a second peripheral conduit segment and a third peripheral conduit segment, a stationary valve piece disposed in said chamber of said housing and attached to said cover, and including two inlet passages formed therein and communicating with said inlet ports of said cover for receiving the cold water and the hot water from said inlet ports of said cover respectively, and including a first outlet passage and a second outlet passage formed therein and communicating with said first and said second outlet ports of said cover respectively, a sealing member engaged with said conduit member of said cover and engaged with said stationary valve piece for making a water tight seal between said stationary valve piece and said cover, said cover including two first peripheral ribs for forming said first peripheral conduit segments and for forming two orifices in said cover which are communicating with said inlet ports of said cover for guiding the cold water and the hot water from said inlet ports of said cover to said inlet passages of said stationary valve piece respectively, said cover including a second peripheral rib and a third peripheral rib for forming said second and said third peripheral conduit segments and for forming a space and an aperture in said cover which are communicating with said first and said second outlet ports of said cover respectively and for guiding the mixed water to flow from said first and said second outlet passages of said stationary valve piece to said first and said second outlet ports of said cover respectively, said space defined by said second peripheral rib including an oblong structure having a primary space portion offset and spaced from said first and said second outlet ports of said cover and a narrowed and curved neck portion communicating with said first outlet port of said cover for guiding the mixed water to flow from said first outlet passage of said stationary valve piece to said first outlet port of said cover, and said aperture in said cover and formed by said second peripheral rib including an oblong structure communicating with said second outlet port of said cover for guiding the mixed water to flow from said second outlet passage of said stationary valve piece to said second outlet port of said cover, a movable valve piece movably and rotatably received and engaged in said chamber of said housing and engaged with said stationary valve piece, and including an outlet pathway formed therein, and said movable valve piece being movable relative to said stationary valve piece for selectively aligning said outlet pathway of said movable valve piece with either said first outlet passage or said second outlet passage of said stationary valve piece and for controlling the mixed water to flow out through either said first or said second outlet passage of said stationary valve piece, said movable valve piece including an inlet pathway formed therein and communicating with said inlet passages of said stationary valve piece, and said movable valve piece being rotatable relative to said stationary valve piece for adjusting a communication area of said inlet pathway of said movable valve piece with said inlet passages of said stationary valve piece and for adjusting a flowing quantity of the cold water and the hot water through said inlet passages of said stationary valve piece and for adjusting a water temperature of a mixed water when said outlet pathway of said movable valve piece is communicating with either said first outlet passage or said second outlet passage of said stationary valve piece, and an actuating device coupled to said movable valve piece for moving and rotating said movable valve piece relative to said stationary valve piece to selectively aligning said outlet pathway of said movable valve piece with either said first outlet passage or said second outlet passage of said stationary valve piece and to selectively rotating said movable valve piece relative to said stationary valve piece and to adjust the communication area of said inlet pathway of said movable valve piece with said inlet passages of said stationary valve piece and to adjust the flowing quantity of the cold water and the hot water through said inlet passages of said stationary valve piece and to adjust the water temperature of the mixed water.
