ABSTRACT:
A novel tunable hydraulic valve assembly, adaptable to a standard direct acting hydraulic shock absorber, variably responsive to a plurality of selected ranges of fluid pressure differentials to provide a plurality of fluid flow paths between fluid containing portions of the shock absorber, and a method for achieving same, is disclosed. The valve assembly comprises a plurality of deflectable valve disks with flow ports, in stacked abutting relationship whereby selected ranges of fluid pressure differentials deflect variable numbers of valve disks providing varying fluid flow paths therebetween. The valve assembly of the present invention is shown to be adapted to use in both the piston, tunably affecting fluid flow between portions of the pressure cylinder on either side of a reciprocable piston disposed therein, and the base valve assembly, tunably affecting fluid flow between the pressure cylinder and the fluid reservoir.
