Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A mixer valve for two different fluids, said valve comprising the combination of: a. a selector member having outlet port means and an inlet port means arranged to be selectively moved into communication with either one or both of the sources of different fluids; b. means for limiting said selEctor member to angular movement; and c. a first hollow bushing member surrounding said selector member, said bushing member having discharge means and means for closing the outlet port of said selector member, said bushing member being axially movable between valve open and valve closed positions.
Claim 2
Dependent Claim
95 words
A mixer valve for two different fluids, said valve comprising the combination of: a. a selector member having outlet port means and an inlet port means arranged to be selectively moved into communication with either one or both of the sources of different fluids; b. means for limiting said selEctor member to angular movement; and c. a first hollow bushing member surrounding said selector member, said bushing member having discharge means and means for closing the outlet port of said selector member, said bushing member being axially movable between valve open and valve closed positions.
Claim 3
Dependent Claim
45 words
A mixer valve in accordance with claim 1 further including a tubular sleeve member having fluid discharge means and two independent inlet port means adapted to be placed in communication with the source of the two different fluids, said sleeve member surrounding said selector member.
Claim 4
Dependent Claim
54 words
The mixer valve in accordance with claim 2 wherein said inlet ports of said tubular sleeve member are on a common radius and said inlet port means of said selector member is arcuate, the length of said arcuate inlet port extending sufficiently to be in simultaneous communication with both said sleeve member inlet ports.
Claim 5
Dependent Claim
44 words
The mixer valve in accordance with claim 2 wherein said selector member includes an axial bore in communication with said inlet port means and said outlet port means thereof, said outlet port means of said selector member comprising a plurality of radially extending openings.
Claim 6
Dependent Claim
48 words
Mixing valve in accordance with claim 4 further including first gasket means interposed between adjacent confronting surface of said selector member and said bushing member, said first gasket means being positioned on both sides of a transverse axis defined by said outlet port means of said selector member.
Claim 7
Dependent Claim
65 words
The mixer valve in accordance with claim 2 wherein said sleeve member is internally threaded and said means for limiting said selector member to angular movement comprises at least one threaded disclike member in mating engagement with the threads of said sleeve member, said selector member having a portion upon which said disclike member is seated to thereby prevent axial movement of said selector member.
Claim 8
Dependent Claim
70 words
The mixer valve in accordance with claim 2 wherein in the closed position of said mixer valve the wall of said first hollow bushing member covers said outlet port means of said selector member, said first hollow bushing member having a plurality of slots in the wall thereof adapted to be positioned over said outlet port means of said selector member when said mixer valve is in the open position.
Claim 9
Dependent Claim
65 words
The mixer valve in accordance with claim 2 wherein said selector member includes a noncircular end portion in mating engagement with a similarly shaped portion of said first hollow bushing member whereby said first hollow bushing member and said selector member are adapted to move angularly in unison and said first hollow bushing member is adapted to move axially with respect to said selector member.
Claim 10
Dependent Claim
49 words
The mixer valve in accordance with claim 2 further including a second bushing member threadably engaged with said tubular sleeve member said second bushing member surrounding one end portion of said first bushing member and having means cooperating therewith for limiting the axial movement of said first bushing member.
Claim 11
Dependent Claim
56 words
The mixer valve in accordance with claim 2 wherein said inlet port means of said tubular sleeve member are located in a transverse end wall thereof that is in opposition to the end surface of said selector member containing said inlet port means thereof, there being further included second gasket means interposed between said opposing surfaces.
