Damping force adjustable hydraulic shock absorber

Abstract

Abstract PURPOSE:To secure optimum comfortable ride by providing a movable diaphragm energizing a valve member to the valve closing direction by atmospheric pressure and varying damping force generated by regulating atmospheric pressure. CONSTITUTION:A valve mechanism 26 for regulating damping force is provided on an oil path 23 communicating oil chambers A and B in an inner cylinder 13B divided by a piston 17. The valve mechanism 26 is provided with a valve member 32 sticked to a diaphragm 34 which is a movable wall. And the movable wall energizes the valve member 26 to the valve closing direction by atmospheric pressure supplied from outside to reduce opening area of the oil path 23, and damping force can be raised.
