Patent ID: 8720857

Claim:
A tunable fluid end comprising at least one subassembly, each subassembly comprising a housing, a suction valve, a discharge valve, and a plunger, at least one said valve comprising a tunable radial array, and at least one said valve comprising a tunable valve seat; wherein said tunable radial array comprises a valve body having guide means to maintain valve body alignment, a peripheral valve seat interface, a fenestrated peripheral groove spaced apart from a central reservoir, and a plurality of viscoelastic body elements disposed in said valve body; wherein said tunable valve seat comprises a mating surface longitudinally spaced apart from a lateral support mounting surface, together with a lateral support assembly, said lateral support assembly being adjustably secured on said mounting surface and comprising a plurality of circular viscoelastic support elements, each said support element comprising a support circumferential tubular area; wherein said plurality of viscoelastic body elements comprises a reservoir element, a groove element, and a plurality of fenestration elements coupling said reservoir element with said groove element, said viscoelastic groove element comprising a groove circumferential tubular area; wherein said viscoelastic reservoir element has at least a first predetermined resonant frequency substantially replicating a resonant frequency of said housing; wherein said plurality of fenestration elements coupling said reservoir element with said groove element have at least a second predetermined resonant frequency related to said first predetermined resonant frequency and achieved through choice of tensile strength of said fenestration elements; and wherein said groove circumferential tubular area and each said support circumferential tubular area comprises at least one shear thickening material having at least a third predetermined resonant frequency related to said first and second predetermined resonant frequencies.
