Claims

[Scope of utility model registration request]

(1) The inside of the cylinder is divided into an upper chamber and a lower chamber by a piston attached to the tip of a piston rod inserted into the cylinder, and the desired damping force is generated through the piston. In the hydraulic shock absorber, a plurality of ports of different diameters are provided in the vicinity of the tip of the piston rod to face a port that is bored in the wall in the vicinity and allows communication between the upper chamber and the lower chamber in the cylinder. It has a control valve that has a port and is arranged to be able to move up and down and freely rotate, and the control valve is fixed to the lower end of the control rod that passes through the piston rod in the axial direction, and the control valve is fixed to the lower end of the control rod that passes through the piston rod in the axis direction. A hydraulic shock absorber characterized in that the hydraulic shock absorber is formed so as to vertically move or rotate a Kositrol valve by rotating it, thereby communicating or blocking communication between an upper chamber and a lower chamber in a cylinder through the respective ports.

(2) When the control valve moves up and down, its port faces the port bored in the wall near the tip of the piston rod to communicate between the upper chamber and the lower chamber in the cylinder, and when it rotates, each port The hydraulic shock absorber according to claim 1, which is a registered utility model, is formed so as not to interrupt communication between the upper chamber and the lower chamber in the cylinder via the cylinder.

(3) When the control valve rotates, its port faces the port drilled in the wall near the tip of the piston rod to communicate between the upper chamber and the lower chamber in the cylinder, and when it moves up and down, each port The hydraulic shock absorber according to claim 1, which is formed to block communication between an upper chamber and a lower chamber in a cylinder via the cylinder.
