Abstract: An impulse tolerant valve body is longitudinally deformable, acting through its convex valve seat interface and a concave valve seat to beneficially reduce closing energy impulse amplitude, increase impulse duration, damp induced resonance vibrations, and narrow the characteristic vibration spectrum. Elastic longitudinal valve body deformability results from elasticity in valve body construction materials and, in certain embodiments, from at least one fluid-filled internal elastic space in fluid communication with at least one internal surge chamber via at least one fluid flow restrictor. Fluid flow from elastic space to surge chamber allows substantially central longitudinal valve body compression, followed by elastic valve body rebound with reverse fluid flow. Beneficial effects are achieved through dissipation of impulse energy as heat lost through fluid flow friction and valve body hysteresis.

Abstract: An impulse tolerant valve body has at least one internal variable-volume space capable of elastic longitudinal compression and rebound. Each such space is filled with incompressible fluid and has fluid communication with at least one internal surge chamber. A closing energy impulse due to valve closing causes elastic longitudinal compression of at least one variable-volume space, with consequent flow of incompressible fluid to at least one surge chamber via at least one fluid flow restrictor. During subsequent elastic rebound, incompressible fluid flows from at least one surge chamber to at least one variable-volume space, again via at least one fluid flow restrictor. A portion of valve closing impulse energy is thus redistributed as heat generated due to fluid friction losses and valve body hysteresis loss. Valve closing energy impulse amplitude is thereby reduced, impulse duration is increased, vibration spectrum is narrowed and induced resonance vibrations are damped.
