Abstract

Abstract Valve apparatus and method with an elastomeric disk fixedly disposed between inlet and outlet members and being deformable to permit flow through the inlet to the outlet. Deformation of the disk in the direction of pressure through the outlet is limited. The elastomeric disk can be circular with a linear or non-linear slit and be clamped between the inlet and outlet members. The structure for limiting disk deformation can take the form of a pilot integrated into, and extending across, the inlet member in centrally or non-centrally apertured form.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 80 words
Apparatus comprising an inlet member; an outlet member physically connected to said inlet member; an elastomeric disk fixedly disposed between the inlet and outlet members being deformable to permit flow through said inlet to said outlet; and means in said apparatus spaced from said disk for limiting the deformation thereof in the direction of pressure through said outlet to said disk and including a pilot for facilitating the deformation of said disk in the direction of pressure through said inlet.
Claim 2
Dependent Claim 80 words
Apparatus comprising an inlet member; an outlet member physically connected to said inlet member; an elastomeric disk fixedly disposed between the inlet and outlet members being deformable to permit flow through said inlet to said outlet; and means in said apparatus spaced from said disk for limiting the deformation thereof in the direction of pressure through said outlet to said disk and including a pilot for facilitating the deformation of said disk in the direction of pressure through said inlet.
Claim 3
Dependent Claim 12 words
Apparatus as defined in claim 1 wherein said elastomeric disk is circular.
Claim 4
Dependent Claim 17 words
Apparatus as defined in claim 1 wherein said disk is clamped between the inlet and outlet members.
Claim 5
Dependent Claim 15 words
Apparatus as defined in claim 1 wherein said disk is positioned upon said outlet member.
Claim 6
Dependent Claim 13 words
Apparatus as defined in claim 1 wherein said disk has a slit therein.
Claim 7
Dependent Claim 14 words
Apparatus as defined in claim 5 wherein said slit in said disk is linear.
Claim 8
Dependent Claim 14 words
Apparatus as defined in claim 5 wherein said slit in said disk is nonlinear.
Claim 9
Dependent Claim 16 words
Apparatus as defined in claim 1 wherein the limiting means is integrated into said inlet member.
Claim 10
Dependent Claim 15 words
Apparatus as defined in claim 1 wherein the limiting means extends across said inlet member.
Claim 11
Dependent Claim 19 words
Apparatus as defined in claim 9 wherein said limiting means comprises an apertured disk extending across said inlet member.
Claim 12
Dependent Claim 13 words
Apparatus as defined in claim 10 wherein said apertured disk is non-centrally apertured.
Claim 13
Dependent Claim 15 words
Apparatus as defined in claim 10 wherein said apertured disk has a plurality of apertures.
Claim 14
Dependent Claim 12 words
Apparatus as defined in claim 12 wherein said apertures are symmetrically disposed.
Claim 15
Dependent Claim 12 words
Apparatus as defined in claim 12 wherein said apertures are oppositely disposed.
Claim 16
Dependent Claim 24 words
Apparatus as defined in claim 1 wherein said pilot spans said inlet member and extends short of the position where the disk is clamped.
Claim 17
Independent Claim 85 words
The method of controlling fluid flow, which comprises the steps of: (1) deforming an elastomeric disk fixedly disposed between inlet and outlet members to permit flow through said inlet member and to said outlet member; and (2) limiting the deformation of said disk in the direction of pressure through said outlet member to said disk by a member, fixedly disposed between said inlet and outlet members, which facilitates the deformation of said disk in the direction of pressure through said inlet member to said disk.
Claim 18
Independent Claim 85 words
The method of controlling fluid flow, which comprises the steps of: (1) deforming an elastomeric disk fixedly disposed between inlet and outlet members to permit flow through said inlet member and to said outlet member; and (2) limiting the deformation of said disk in the direction of pressure through said outlet member to said disk by a member, fixedly disposed between said inlet and outlet members, which facilitates the deformation of said disk in the direction of pressure through said inlet member to said disk.
Claim 19
Dependent Claim 39 words
The method of claim 16 wherein said elastomeric disk is circular, positioned upon said outlet member and clamped between the inlet and outlet members, with a slit therein, and the step of deforming said disk comprises expanding said slit.
Claim 20
Dependent Claim 42 words
The method of claim 16 wherein the limiting means is integrated into said inlet member, extends across said inlet member and the step of limiting said deformation comprises the step of restricting the motion of said disk by engaging said limiting means.
Claim 21
Dependent Claim 38 words
The method of claim 16 wherein said limiting means comprises a non-centrally apertured disk extending across said inlet member, with a plurality of symmetrically and oppositely disposed apertures, comprising a pilot for facilitating the deformation of said disk.
