Abstract
A reed valve in the form of a plate fixed at one end and bendable into and out of contact with a valve seat is operated by differential pressures and acts as a check-valve. The reed valve has cavities in the surface thereof with unitary strengthening frame members separating these cavities. Specific patterns of cavities and frame members are employed to achieve the desired performance of the valve.
Claims17
A reed valve comprising a reed element having a first surface, said first surface including cavities therein, said cavities being discontinuous, one from another, and structurally independent, and a planar peripheral boundary and frame members extending between said discontinuous cavities, said boundary and said frame members having surface continuity there among, said cavities extending into said element to define membranes between said frame members.
A reed valve comprising a reed element having a first surface, said first surface including cavities therein, said cavities being discontinuous, one from another, and structurally independent, a planar peripheral boundary and frame members extending between said discontinuous cavities, said boundary and said frame members having surface continuity there among, said cavities forming a pattern of symmetrical figures in plan wherein said symmetrical figures are in nested arrangement in said pattern and said pattern terminates at said planar peripheral boundary.
A reed valve comprising a reed element having a first surface, said first surface including cavities therein, a planar peripheral boundary and frame members extending between said cavities such that said frame member and said boundaries define the extent of said cavities, and a base for holding said reed element, the sum width of said frame members between adjacent cavities in any row of cavities, as measured in a direction parallel to said base, being substantially constant between said boundries.
A reed valve comprising a reed element having first and second surfaces, said surfaces including cavities therein, planar peripheral boundaries and frame members extending between said cavities such that said frame members and said boundaries define the extent of said cavities to define patterns of symmetrical figures in nested arrangement, said patterns on said sides being identical, and a base for holding said reed element.
