ABSTRACT:
A nonlinear shock absorber is disclosed. The device has a housing filled with hydraulic fluid and contains a relatively heavy mass or piston supported by a helical coil. The helical coils disposed and shaped so as to provide a nonlinear resistance to a shock applied to the housing. During shock absorption fluid flows contra to the piston movement with a corresponding elongation of the helical coil spring causing the coil spring to engage an inner wall of the housing to provide for frictional dampening.
