Single handle mixing faucet

A mixing valve for mixing hot and cold water sources and providing an output thereof comprising:

• a valve housing having a central bore having a longitudinal axis, first and second passageways and an outlet;
• first and second inlets on said housing for respectively receiving said hot and cold water sources and said inlets communicating with said first and second passageways;
• a head-piece casing mounted on said housing and rotatable about said longitudinal axis;
• a first valve plate mounted within said bore having a surface parallel to said longitudinal axis and having first and second inlet bores communicating with said first and second passageways, respectively, and an outlet bore communicating with said outlet;
• handle means pivotally connected to said head-piece;
• a pusher plate supported in said central bore and movable parallel to said longitudinal axis;
• a second valve plate carried by said pusher plate, said second valve plate having a surface positioned parallel to said longitudinal axis, said second valve plate surface having a mixing passage and said second valve plate adapted to slideably engage said first valve plate surface to position said mixing passage in communication with said first and second inlet bores and said outlet bore;
• first means connecting said pusher plate to said handle for translating a displacement of said handle in a direction substantially parallel to said longitudinal axis to a corresponding displacement of said second valve plate parallel to said longitudinal axis to regulate the volume of mixed water;
• and,
• pivot means for translating a rotational displacement of said head-piece to a pivotal displacement of said pusher plate about an axis perpendicular to said longitudinal axis whereby said second valve plate regulates the mixture of hot and cold water, said pivot means including a slide guide in said head-piece and rotatable about said longitudinal axis, and a sliding pad connected to said pusher plate, said sliding pad being displaced from said longitudinal axis and adapted to cooperatively engage said slide guide.
