A fluid mixing valve comprising: a hollow, generally cylindrical, vertically arranged valve body closed at one end and having a rotatable control stem extending through a seal at the opposite end; said body having a tapered bore and two axially spaced inlets, and spaced therefrom, two axially spaced outlets and a pair of laterally spaced radial outlets; a first valve sleeve having a cylindrical bore externally tapered and rotatably mounted in said tapered bore and nonmovable axially; said first valve sleeve having a first pair of axially spaced and aligned inlet ports, a second pair of axially spaced and aligned outlet ports, and a third pair of axially spaced aligned outlet ports, said pairs of ports being angularly spaced around said valve sleeve and respectively aligned laterally of said inlets and outlets; whereby said pairs of ports may be interchangeably employed as inlets and outlets respectively for selective registry on rotation of said sleeve with said inlets and with one of said three sets of outlets; the registry of the selected pair of ports with said inlets being variable for regulating volume of flow of fluid through said inlets to a mixing chamber within said sleeve; an actuator sleeve rotatably mounted on said stem and having a sliding connection with said sleeve valve for rotating the same but adapted for relative axial movement; a semicylindrical valve element slidably mounted for axial movement in the bore of said first valve sleeve and being nonrotatable relative to said body; said valve element axially connected loosely to said actuator sleeve adapted for controlled axial adjustments on axial adjustment of said actuator sleeve; said valve element being provided with an inlet port and an outlet port angularly spaced therefrom; said valve element inlet port being angularly aligned with and overlapping said valve body inlets for variably determining the flow of fluids through either or both of said inlets to said mixing chamber; the outlet port of said valve element being in registry with one body outlet; a second semicylindrical valve element opposed from said first valve element slidably mounted for axial movement in the bore of said first valve sleeve and Being in nonrotatable relation to said body; said second valve element being axially and slidably mounted upon said control stem for movement independent of said first valve element; ball and angular slot means interconnecting said stem and second valve element, whereby rotation of said stem effects controlled axial adjustments of said second valve element; said second valve element being provided with a pair of angularly spaced outlet ports; one outlet port registering with said second valve body outlet and the other of said second valve element outlet ports being in lateral registry with said body axially spaced outlets selectively registerable with one or both of said axially spaced outlets adapted for delivery through either or both thereof fluids from said mixing chamber; rotation of said actuator sleeve regulating the degree of registry of one pair of said valve sleeve ports with said valve body inlets and with said first valve element inlet port controlling the volume of fluids admitted to said mixing chamber, and at the same time establishing outlet connection to any of the body outlets; axial displacement of said actuator sleeve regulating the degree of registry of said first valve element inlet port with said valve body inlet ports to control the proportion of fluid mix admitted from the valve body inlet ports to said mixing chamber; rotation of said stem effecting axial displacement of said second valve element whereby one of its outlet ports is in selective variable registry with said pair of axially spaced body outlets or either of them.

A fluid mixing valve comprising: a hollow, generally cylindrical, vertically arranged valve body closed at one end and having a rotatable control stem extending through a seal at the opposite end; said body having a tapered bore and two axially spaced inlets, and spaced therefrom, two axially spaced outlets and a pair of laterally spaced radial outlets; a first valve sleeve having a cylindrical bore externally tapered and rotatably mounted in said tapered bore and nonmovable axially; said first valve sleeve having a first pair of axially spaced and aligned inlet ports, a second pair of axially spaced and aligned outlet ports, and a third pair of axially spaced aligned outlet ports, said pairs of ports being angularly spaced around said valve sleeve and respectively aligned laterally of said inlets and outlets; whereby said pairs of ports may be interchangeably employed as inlets and outlets respectively for selective registry on rotation of said sleeve with said inlets and with one of said three sets of outlets; the registry of the selected pair of ports with said inlets being variable for regulating volume of flow of fluid through said inlets to a mixing chamber within said sleeve; an actuator sleeve rotatably mounted on said stem and having a sliding connection with said sleeve valve for rotating the same but adapted for relative axial movement; a semicylindrical valve element slidably mounted for axial movement in the bore of said first valve sleeve and being nonrotatable relative to said body; said valve element axially connected loosely to said actuator sleeve adapted for controlled axial adjustments on axial adjustment of said actuator sleeve; said valve element being provided with an inlet port and an outlet port angularly spaced therefrom; said valve element inlet port being angularly aligned with and overlapping said valve body inlets for variably determining the flow of fluids through either or both of said inlets to said mixing chamber; the outlet port of said valve element being in registry with one body outlet; a second semicylindrical valve element opposed from said first valve element slidably mounted for axial movement in the bore of said first valve sleeve and Being in nonrotatable relation to said body; said second valve element being axially and slidably mounted upon said control stem for movement independent of said first valve element; ball and angular slot means interconnecting said stem and second valve element, whereby rotation of said stem effects controlled axial adjustments of said second valve element; said second valve element being provided with a pair of angularly spaced outlet ports; one outlet port registering with said second valve body outlet and the other of said second valve element outlet ports being in lateral registry with said body axially spaced outlets selectively registerable with one or both of said axially spaced outlets adapted for delivery through either or both thereof fluids from said mixing chamber; rotation of said actuator sleeve regulating the degree of registry of one pair of said valve sleeve ports with said valve body inlets and with said first valve element inlet port controlling the volume of fluids admitted to said mixing chamber, and at the same time establishing outlet connection to any of the body outlets; axial displacement of said actuator sleeve regulating the degree of registry of said first valve element inlet port with said valve body inlet ports to control the proportion of fluid mix admitted from the valve body inlet ports to said mixing chamber; rotation of said stem effecting axial displacement of said second valve element whereby one of its outlet ports is in selective variable registry with said pair of axially spaced body outlets or either of them.
Claim 3
Dependent Claim
30 words
In the mixing valve of claim 1, an axially extending adjustable stop on said valve body normally spaced from said actuator sleeve for limiting axial adjustments thereof in one direction.
Claim 4
Dependent Claim
29 words
In the mixing valve of claim 1, spring means interposed between said valve body and first valve sleeve normally biasing said sleeve with respect to said body tapered bore.
Claim 5
Dependent Claim
52 words
In the mixing valve of claim 1, the external taper of said first valve sleeve including an annular body portion of reduced diameter, and an exteriorly tapered ring of bearing material on an over said annular body portion and projecting laterally of said valve sleeve for engagement with the body tapered bore.
