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.
