Beschreibung
Zusammenfassung:	In the disclosed hydraulic shock absorber, the flow of hydraulic fluid induced in each of extension and compression hydraulic fluid passages by sliding movement of a piston (3) is controlled by a main disk valve (14, 26) to generate damping force. The valve opening pressure of the main disk valve is adjusted by the pressure in a back-pressure chamber (18, 30). In a low piston speed region, the main disk valve closes a back-pressure chamber inlet passage (15, 27). Therefore, the pressure in the back-pressure chamber will not rise, and sufficiently small damping force is obtained. When the main disk valve opens, the back-pressure chamber inlet passage opens simultaneously. Consequently, the pressure in the back-pressure chamber rises, and the damping force increases.
