Abstract
Abstract A mixing valve comprising a valve body having the configuration of a truncated cone, at least two independent fluid inlets and an independent fluid outlet for each inlet. A first valve seat is located between one of the inlets and its outlet and a second valve seat is located between the other of the inlets and its outlet. Two plungerlike valve elements are reciprocally mounted in the valve body, each element having one end adapted to cooperate with one of the valve seats and a free end extending beyond the conical surface of the valve body. An actuator cap is mounted on the valve body and has an inner surface in the configuration of a truncated cone, adapted to contact the free ends of the valve elements. The actuator cap is movable vertically to regulate the flow of fluid from full on to full off. The conical inner surface of the actuator cap has at least one flat whereby rotation of the cap will regulate the fluid flow over the range between all from one outlet to all from the other outlet.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
302 words
A valve means comprising a valve body having the configuration of a truncated cone, at least two fluid inlet passages within said valve body, a separate fluid outlet passage within said body for each inlet passage and being adjacent thereto, each outlet passage being joined to its adjacent inlet passage by a first opening in said valve body containing a valve seat, each outlet passage having a second opening coaxial with said first opening and extending from said outlet passage to said conical surface of said valve body, each of said second openings containing a valve element, each of said valve elements having a first end adapted to cooperate with its adjacent valve seat and a second end extending beyond said conical surface of said Valve body, each of said valve elements being movable toward and away from its adjacent valve seat to regulate the flow of fluid therethrough, means for urging said valve elements away from their respective valve seats, an actuator cap surrounding said valve body, said actuator cap having an inner surface contacting said second ends of said valve elements, said inner surface being conical and having at least one flat therein, said actuator cap being movable axially whereby said first ends of said valve elements are caused to move equally and simultaneously toward and away from their respective valve seats by virtue of the coaction of said second ends of said valve elements and said conical inner surface of said actuator cap, said actuator cap being rotatable about its axis whereby said at least one flat may be brought into contact with said second end of one of said elements to move said first end of said last mentioned valve element toward and away from its respective valve seat while the other of said valve elements remains unchanged.
Claim 2
Dependent Claim
302 words
A valve means comprising a valve body having the configuration of a truncated cone, at least two fluid inlet passages within said valve body, a separate fluid outlet passage within said body for each inlet passage and being adjacent thereto, each outlet passage being joined to its adjacent inlet passage by a first opening in said valve body containing a valve seat, each outlet passage having a second opening coaxial with said first opening and extending from said outlet passage to said conical surface of said valve body, each of said second openings containing a valve element, each of said valve elements having a first end adapted to cooperate with its adjacent valve seat and a second end extending beyond said conical surface of said Valve body, each of said valve elements being movable toward and away from its adjacent valve seat to regulate the flow of fluid therethrough, means for urging said valve elements away from their respective valve seats, an actuator cap surrounding said valve body, said actuator cap having an inner surface contacting said second ends of said valve elements, said inner surface being conical and having at least one flat therein, said actuator cap being movable axially whereby said first ends of said valve elements are caused to move equally and simultaneously toward and away from their respective valve seats by virtue of the coaction of said second ends of said valve elements and said conical inner surface of said actuator cap, said actuator cap being rotatable about its axis whereby said at least one flat may be brought into contact with said second end of one of said elements to move said first end of said last mentioned valve element toward and away from its respective valve seat while the other of said valve elements remains unchanged.
Claim 3
Dependent Claim
262 words
The structure claimed in claim 1 wherein each of said valve elements for an adjacent pair of inlet and outlet passages comprises a resilient hat-shaped diaphragm having a cylindrical body open at one end with an annular rim thereabout and closed at the other end by a web portion having an exterior surface and an inner surface within said cylindrical body, said exterior surface of said web portion adapted to cooperate with said valve seat in said opening between said inlet and outlet passages, said second opening from said outlet passage through said conical surface of said valve body having a large diameter portion adjacent said conical surface and a small diameter portion adjacent said outlet passage and an annular shoulder therebetween, a perforated disc threadedly engaged in said large diameter portion of said second opening and holding said diaphragm within said second opening with said annular rim abutting said annular shoulder in fluidtight fashion and with said exterior surface of said web portion facing and spaced from said valve seat, a plunger being slidably mounted in said perforation in said disc, one end of said plunger extending within said cylindrical body of said diaphragm and abutting the inside surface of the web portion thereof, the other end of said plunger extending beyond said conical surface of said valve body and contacting said inner surface of said actuator cap whereby movement of said actuator cap will move said plunger axially, moving said web portion toward and away from said valve seat to regulate the fluid flow between said inlet and outlet passages.
Claim 4
Dependent Claim
245 words
The structure claimed in claim 1 wherein each of said valve elements for an adjacent pair of inlet and outlet passages comprises a resilient hat-shaped diaphragm having a cylindrical body open at one end with an annular rim thereabout and closed at the other end by a web portion having an inner surface within said cylindrical body and an exterior surface, said second opening from said outlet passage through said conical surface of said valve body having a large diameter portion adjacent said conical surface and a small diameter portion adjacent said outlet passage with an annular shoulder therebetween, a perforated disc threadedly engaged in said large diameter portion of said second opening and holding said diaphragm therein with said annular rim abutting said shoulder in fluidtight fashion, said cylindrical body extending through said perforation in said disc and said exterior surface of said web extending beyond said conical surface of said valve body, said valve seat in said opening joining said inlet and outlet passages extending through said outlet passage, said second opening and into said cylindrical body of said diaphragm, the end of said valve seat being spaced from the inner surface of said diaphragm web portion, said exterior surface of said diaphragm web portion contacting said inner surface of said actuator cap whereby movement of said actuator caP will move said web portion toward and away from said valve seat to regulate the fluid flow therethrough between said inlet and outlet passages.
