ABSTRACT:
A fluid vibration damper, such as, a shock absorber includes a cylinder and piston combination in which the piston head travels through a fluid-filled cylinder and has fluid bypass openings in its external surface forming one or more recesses of predetermined cross-sectional configurations and sizes whereby to regulate fluid flow past the piston head according to a performance curve. The bypass openings can be formed in interchangeable elements so as to permit selective variations in the fluid flow characteristics of each particular size or design of shock absorber according to a specific force performance curve.
