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.
Claims19
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.
2 more elements
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.
