Abstract
Abstract A valve having spaced annular seats converging toward each other with a single moving annular valve member of flexible material of low inertia and fast response engaging the annular seats in proportion to the pressures of the fluid which it handles on either side of the valve including an adjustment of one of the seats. This valve may also incorporate a temperature control for providing a reverse flow.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A valve assembly comprising a body having inlet and outlet conduits, first and second annular valve seats on said body located between said conduits and having sealing surfaces, the sealing surfaces of said valve seats converging toward each other, a flexible annular valve member disposed between said first and second seats and normally in engagement therewith, said valve member having its opposite seat engaging faces inclined with reference to a plane between said sealing surfaces, whereby fluid pressure applied on one side of the valve member will cause deflection of the extremities of the valve member toward each other to unseat the valve, and fluid pressure applied on the other side of the valve member will cause deflection of the extremities of the valve member away from each other to seat the valve.
Claim 2
Dependent Claim
133 words
A valve assembly comprising a body having inlet and outlet conduits, first and second annular valve seats on said body located between said conduits and having sealing surfaces, the sealing surfaces of said valve seats converging toward each other, a flexible annular valve member disposed between said first and second seats and normally in engagement therewith, said valve member having its opposite seat engaging faces inclined with reference to a plane between said sealing surfaces, whereby fluid pressure applied on one side of the valve member will cause deflection of the extremities of the valve member toward each other to unseat the valve, and fluid pressure applied on the other side of the valve member will cause deflection of the extremities of the valve member away from each other to seat the valve.
Claim 3
Dependent Claim
25 words
A valve assembly as in claim 1 wherein one of the seats is movable toward the other seat to vary the pressure on the valve.
Claim 4
Dependent Claim
23 words
A valve assembly as in claim 1 wherein the valve member has a thickness gradually diminishing toward the extremities of the valve member.
Claim 5
Dependent Claim
18 words
A valve assembly as in claim 1 wherein the valve member has a thickness which is constant throughout.
Claim 6
Dependent Claim
16 words
A valve assembly as in claim 1 wherein the valve member is laminated of plastic materials.
Claim 7
Dependent Claim
16 words
A valve assembly as in claim 1 wherein the valve member is metal and plastic material.
Claim 8
Dependent Claim
28 words
A valve assembly as in claim 1 wherein the inclined faces of the valve member have an inherent tendency to spread apart to provide a greater included angle.
Claim 9
Dependent Claim
19 words
A valve assembly as in claim 1 wherein there are a plurality of valves between the inlet and discharge.
Claim 10
Dependent Claim
106 words
A valve assembly comprising a body having inlet and outlet conduits, first and second annular valve seats on said body located between said conduits and having sealing surfaces, the sealing surfaces of said valve seats converging toward each other, a flexible annular valve member disposed between said first and second seats and normally in engagement therewith, said valve member having its opposite seat engaging faces inclined with reference to a plane between said sealing surfaces, said valve member being formed of a plurality of materials of different coefficients of expansion whereby a control of the valve member occurs by the temperature to which it is subjected.
Claim 11
Dependent Claim
106 words
A valve assembly comprising a body having inlet and outlet conduits, first and second annular valve seats on said body located between said conduits and having sealing surfaces, the sealing surfaces of said valve seats converging toward each other, a flexible annular valve member disposed between said first and second seats and normally in engagement therewith, said valve member having its opposite seat engaging faces inclined with reference to a plane between said sealing surfaces, said valve member being formed of a plurality of materials of different coefficients of expansion whereby a control of the valve member occurs by the temperature to which it is subjected.
