Abstract
Abstract A vortex valve with tangentially opposed control and supply ports with the relative port sizes varied to control the output characteristics and produce a high or tailored gain at a desired pressure value and/or to introduce a pronounced negative resistance in an operating range of the valve. The valve is also combined with a fluid operated pressure regulating circuit, in which it is used as a flow controller.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
An opposing control vortex valve device comprising: a vortex chamber including a peripheral wall and an outlet located inside of said peripheral wall; a first inlet port means in direct communication with said vortex chamber; first means to direct fluid through said first port off center from said outlet into said vortex chamber to tend to produce vortical flow therethrough; a second inlet port means in direct communication with said vortex chamber, with the area of said second inlet port means differing from the area of said first inlet port means; and second means to direct fluid through said second port off center from said outlet into said vortex chamber to tend to produce vortical flow opposing that introduced by said first port means, wherein said first and second inlet port means are the only inlets into said vortex chamber.
Claim 2
Dependent Claim
140 words
An opposing control vortex valve device comprising: a vortex chamber including a peripheral wall and an outlet located inside of said peripheral wall; a first inlet port means in direct communication with said vortex chamber; first means to direct fluid through said first port off center from said outlet into said vortex chamber to tend to produce vortical flow therethrough; a second inlet port means in direct communication with said vortex chamber, with the area of said second inlet port means differing from the area of said first inlet port means; and second means to direct fluid through said second port off center from said outlet into said vortex chamber to tend to produce vortical flow opposing that introduced by said first port means, wherein said first and second inlet port means are the only inlets into said vortex chamber.
Claim 3
Dependent Claim
33 words
The device of claim 1 wherein the area difference between said first and second inlet ports is great enough to produce a vertical pressure flow characteristic in an operating range of said device.
Claim 4
Dependent Claim
32 words
The device of claim 1 wherein the area difference between said first and second inlet port means is sufficient to introduce a negative resistance segment in an operating range of said device.
Claim 5
Dependent Claim
21 words
The device of claim 1 wherein said first and second means direct fluid tangentially to said peripheral wall in opposing directions.
Claim 6
Dependent Claim
51 words
The device of claim 1 wherein said first inlet port means includes a plurality of first inlet ports and the second inlet port means includes a plurality of second inlet ports, with the aggregative area of said second inlet ports differing substantially from the aggregative area of said first inlet ports.
