Abstract
A damping force regulation device for a telescopic shock absorber causes all the hydraulic fluid to flow through a damping force adjuster (variable orifice) which is arranged in series with damping valves, both in expansion and contraction strokes of a piston. The diameter of the orifice is variable to control the damping force over a substantial range and thereby set up a damping characteristic optimum for each specific running condition. During the expansion stroke, a check valve of a base valve is opened to eliminate short suction which would otherwise result in cavitation or noise.
