Abstract
The disclosure provides an improved shock isolator having one or more features of: bidirectional variable metered hydraulic damping orifice; unidirectional flow valve for higher compression damping yet faster rebounding for reset; diverse spring styles for rebound and for compression; scalable back pressure for more efficient hydraulic damping; involute spline for higher torque loading capacity; progressive disk spring assemblies to expand operating frequency range and longevity; spring stack assemblies conform to establish more uniform loading during a stroke.
