登録請求の範囲第１項記載の油圧緩衝器。[Claims for Utility Model Registration] (1) In a hydraulic shock absorber comprising a damping force generating section that enables generation of a desired damping force when a piston section inside the cylinder slides, the damping force generating section is a control valve. It has a damping valve part that can generate damping force of different magnitude depending on the operation of the cylinder, and a leaf valve whose deflection amount is variable depending on an external force that depends on the vibration frequency inside the cylinder. A hydraulic shock absorber characterized in that the pressure is obtained by the internal pressure of a pressure chamber that communicates with the cylinder internal oil chamber via an orifice. (2) The hydraulic shock absorber according to claim 1, wherein the damping force generating section is disposed in the piston section within the cylinder. (3) The hydraulic shock absorber according to claim 1, wherein the damping force generating section is capable of generating a damping force on the rebound side. (4) Hydraulic damping according to claim 1, wherein the control valve has orifices with different diameters, and the orifices are rotated by an external actuator so as to be arbitrarily selected. vessel. (5) Utility model registration claim 1, in which the control valve has a needle facing the valve seat, and is formed so that the amount of oil passing through it can be varied by moving the needle forward and backward using an external actuator. Hydraulic shock absorber as described in section.
