The fluid flow check valve uses a flexure plate or plates to accommodate the valve disk's axial motion required to open and close the valve. The flexure plate also limits the disk's motion in any lateral direction, so the valve disk will align properly with the valve seat and seal when it closes. The flexure plate is a flat, axial spring, made by cutting or otherwise manufacturing spiral cuts in a round, sheet metal disk. Valve qualities such as closing force, size and rigidity to lateral disk motion can be modified by varying the number and configuration of the plates, and by modifying plate characteristics. The compactness of the flexural plate design allows for a shorter valve length and cost as well as increased opportunity for flow optimization.

1. A valve, comprising:a valve body defining a fluid passageway, with a valve seat in the fluid passageway; a valve disk support assembly mounted within the valve body; a front flexure plate mounted on the valve disk support assembly; a valve disk secured to the front flexure plate and disposed within the valve body, the valve disk having a front side and a back side, the valve disk being movable axially within the valve body, the valve being closed when the front side of the valve disk contacts the valve seat; and the front flexure plate having a center and a periphery and being axially extendable to accommodate axial valve disk movement by a plurality of arms connecting between the center and the periphery of the front flexure plate.
