Patent ID: 8708306

Claim:
A tunable valve assembly comprising a valve body and a valve seat having substantially collinear longitudinal axes, said valve seat comprising a lateral support assembly and said valve body having at least one guide, a peripheral seal retention groove, a peripheral valve seat interface, and an elastic valve body base plate; wherein said valve body substantially encloses an internal cavity; wherein said internal cavity substantially encloses a nonlinear spring-mass damper; wherein said valve seat comprises a mating surface longitudinally spaced apart from a lateral support mounting surface; wherein said lateral support assembly is adjustably secured on said lateral support mounting surface, said lateral support assembly having a first resonant frequency approximating a pump housing resonant frequency; wherein said damper has a second resonant frequency approximating said first resonant frequency; and wherein said valve body rebounds from said valve seat with a rebound characteristic frequency lower than said second resonant frequency.
