Abstract
A valve includes a deformable portion connected to a rigid portion. A portion of a surface of a frustoconical body of the rigid portion is disposed adjacent a portion of a surface of a frustoconical body of the deformable portion. A portion of a surface of an upper axially-extending portion of the rigid portion is disposed adjacent a portion of a surface of an upper axially-extending portion of the deformable portion. A portion of the surface of the frustoconical body of the deformable portion that is not disposed adjacent a portion of the surface of the frustoconical body of the rigid portion defines a circumferential void. The circumferential void is in fluid communication with a plurality of upstream radial bypass passages extending through the frustoconical body of the rigid portion.
