Abstract
An impulse tolerant valve assembly comprises a valve body having a longitudinal axis and a central internal cavity, the cavity enclosing a nonlinear spring-mass damper optionally immersed in a dilatant liquid. The central internal cavity is enclosed by a proximal valve body portion and a distal elastic valve body base plate, the base plate having a peripheral valve seat interface. Impulse tolerance results in part from hysteresis heat loss due to compliance of the elastic valve body base plate, as well as from heat loss associated with operation of the nonlinear spring-mass damper. The combined heat loss is reflected in reduction of closing energy impulse amplitude and damping of induced valve body vibrations. Compliance of the elastic valve body base plate increases closing energy impulse duration and narrows the corresponding induced vibration spectrum. The valve body has at least one guide and at least one peripheral seal-retention groove.
