Abstract
A faucet of the type for controlling volume flow of fluids therethrough and for further controlling and varying the temperature of said fluids as determined by the operator of the faucet, for the purpose of effecting mixing of cold and hot water or cold and hot fluids whereby the resultant temperature may be selected from the temperature of the cold fluid supply to the temperature of the hot fluid supply or therebetween.
Claims17
A valve assembly comprising:
- a housing defining a mixing chamber,
- an outlet port formed in said housing and communicating with said mixing chamber,
- means defining at least two elongate chambers within said housing each of which is closed at one end and has an inlet port formed intermediate the ends thereof,
- hollow plug means slidably disposed within each said elongate chambers for movement between first and second positions, each said plug means having a first closed end, a second end open to siad mixing chamber and a lateral opening to its associated elongate chamber, each said plug means closing its chamber inlet port when in its first position and movement of each said plug to a second position resulting in gradual alignment of its lateral opening and its chamber inlet port to establish a flow path from said inlet port to said mixing chamber through said plug means,
- valve operating means for moving said plug means within said elongate chambers, and
- closing means rotatably engageable with the open ends of said plug means for selectively closing said open ends of said plug means to fluid flow.

A mixing valve comprising:
- means defining a hollow housing,
- means within said housing defining a pair of cylindrical valve chambers closed at their lower ends and open at their upper ends to the interior of said housing, one of said chambers having a cold water inlet port formed intermediate the ends thereof and the other of said chambers having a hot water inlet port formed intermediate the ends thereof,
- hollow cylindrical valve spool means slidably disposed within each chamber, said spool means being closed at their lower ends and open at their upper ends to said housing interior and each having at least one lateral opening therethrough coupling its associated chamber with said spool means interior, each said spool means closing one of said water inlet ports to fluid flow when in a first lowered position and the lateral opening in each spool permitting flow through its associated port when said spool means is in a second raised position,
- rotatable body means disposed within said housing for selectively opening and closing said open ends of said spool means to fluid flow,
- means engaging said spool means for moving said spool means from said first to said second position;
- and
- outlet port formed in said housing.
