摘要： A shock absorber is provided with a cylinder, a piston inserted into the cylinder and demarcating an interior of the cylinder into an extension side chamber and a compression side chamber, a piston rod joined to the piston, a damping passage, provided in the piston rod, that communicates with the extension side chamber and the compression side chamber, and a damping force adjustment valve provided in the damping passage. The damping force adjustment valve includes a damping force adjustment unit and a solenoid that drives the damping force adjustment unit to adjust a flow channel resistance. The piston rod includes a yoke into which the damping force adjustment valve is inserted, and a piston holding member mounted on the yoke. The yoke includes a through-hole opening from a side of the yoke and leading to the interior, and a groove provided on a perimeter of the yoke, extending from an anti-piston end, and leading to the through-hole.

摘要： These teachings relate to a device that includes a base having an axis that is centered and perpendicular relative to the base and two or more arms each connected to the base at a base hinge The base hinge rotates the two or more arms away from the axis, and one or more expandable bands are connected with distal ends of the two or more arms. The one or more expandable bands absorb energy from rotating of the two or more arms. The device absorbs energy when an external force is applied along the axis of the base.

摘要： An isolation energy absorber has at least one core post, two supporting boards, multiple first material layers, and multiple second material layers. The at least one core post is a columnar body and is made of zinc metal or zinc alloy that has been metal smelted to have a shear strain capacity of at least 50%. The two supporting boards are respectively disposed on two ends of the isolation energy absorber at a spaced interval. The first material layers and the second material layers are alternately mounted between the two supporting boards and surround the at least one core post.

摘要： A tubular vibration damping device includes an inner shaft member and an outer tubular member connected by a main rubber elastic body. A plurality of first identification protrusions protruding outward are formed apart in a circumferential direction on one axial end surface of the main rubber elastic body, and a plurality of second identification protrusions protruding outward are formed apart in the circumferential direction on another axial end surface. The first identification protrusion and the second identification protrusion are arranged at positions differing from each other in the circumferential direction in an axial projection, and the first identification protrusion and the second identification protrusion have a comprehensive overall pattern in which weight balance is maintained on a central axis of the main rubber elastic body.

摘要： A damper including inner and outer tubes is provided. A piston is slidably disposed within the inner tube. An intermediate tube is positioned radially between the inner and outer tubes. The intermediate tube extends between first and second intermediate tube ends. An intermediate channel is disposed radially between the intermediate and inner tubes. A slanted elliptical seal is positioned inside the intermediate channel and divides the intermediate channel into first and second intermediate channel portions. A first control valve is in fluid communication with the second intermediate channel portion via a first intermediate tube opening. A second control valve is in fluid communication with the first intermediate channel portion via a second intermediate tube opening. The slanted elliptical seal abuts the intermediate tube between the first intermediate tube opening and the first intermediate tube end and between the second intermediate tube opening and the second intermediate tube end.

摘要： A cylinder apparatus is provided with a stopper mechanism that operates when a piston rod extends and moves toward an upper end portion in an inner cylinder. This stopper mechanism includes a second cylinder provided movably relative to the piston rod and including a bottom portion on an upper end side in the inner cylinder and a cylinder portion extending from the bottom portion toward a lower end side, and a second piston provided so as to be able to move along with a movement of the piston rod to be fitted to the second cylinder. While being configured in this manner, the cylinder apparatus is configured in such a manner that a spring member 21 is provided between the second cylinder and a rod guide.
