逆止弁を介装したことを特徴とするダンパ。[Claim for Utility Model Registration] A piston is slidably housed in a cylinder, oil chambers are defined on both sides of the piston, and a piston rod connected to the piston is slidably supported via a bearing at one end of the cylinder. The oil chambers on both sides of the piston are connected via a check valve that prevents the flow of hydraulic oil from the oil chamber on the piston rod side to the oil chamber on the opposite side. An oil sump chamber that compensates for fluctuations is defined by a transparent flexible cover, and a damping valve is installed in the passage that communicates this oil sump chamber with the oil chamber on the piston rod side.
Similarly, the passage connecting the oil sump chamber and the oil chamber on the opposite side of the piston rod prevents the flow of hydraulic oil to the oil sump chamber.
A damper characterized by being equipped with a check valve .

特徴とするダンパ。 A piston is slidably housed in a cylinder to define oil chambers on both sides of the piston, and a piston rod connected to the piston is slidably supported via a bearing at one end of the cylinder, thereby forming oil chambers on both sides of the piston. It is connected via a check valve that prevents the flow of hydraulic oil from the oil chamber on the piston rod side to the oil chamber on the opposite side, and an oil sump chamber is provided outside the cylinder to compensate for oil volume fluctuations caused by changes in the piston rod intrusion volume. A damping valve is installed in the passage defined by a transparent flexible cover and communicating between this oil reservoir chamber and the oil chamber on the piston rod side.
Similarly, a check valve is installed in the passage connecting the oil reservoir chamber and the oil chamber on the opposite side of the piston rod to prevent the flow of hydraulic oil to the oil reservoir chamber, and the cross-sectional area of the piston rod is set to approximately 1 with respect to the cross-sectional area of the piston. A damper characterized by being set to /2.
