Abstract: A shock absorber includes; a free piston that partitions the compression chamber into an expansion-side compression chamber and a contraction-side compression chamber; an expansion-side flow passage that connects the expansion-side chamber with the expansion-side compression chamber; a contraction-side flow passage that connects the contraction-side chamber with the contraction-side compression chamber; an expansion-side bypass valve provided in the expansion-side flow passage to admit only a flow directed from the expansion-side chamber to the expansion-side compression chamber and generate resistance; a contraction-side bypass valve provided in parallel with the expansion-side bypass valve to admit only a flow directed from the expansion-side compression chamber to the expansion-side chamber and generate resistance; an expansion-side elastic stopper configured to stop the free piston at an expansion-side stroke end; and a contraction-side elastic stopper configured to stop the free piston at a contraction-side stroke end.
Abstract translation: 减震器包括: 将压缩室分隔成膨胀侧压缩室和收缩侧压缩室的自由活塞; 将膨胀侧室与膨胀侧压缩室连结的膨胀侧流路; 将收缩侧室与收缩侧压缩室连结的收缩侧流路; 膨胀侧旁通阀,其设置在膨胀侧流路中,仅容纳从膨胀侧室流向膨胀侧压缩室的流动并产生阻力; 收缩侧旁通阀,其与膨胀侧旁通阀并联设置,以仅允许从膨胀侧压缩室引导到膨胀侧室的流动并产生阻力; 膨胀侧弹性止动件,被构造成在膨胀侧行程端止动自由活塞; 以及收缩侧弹性止动件,被构造成在收缩侧行程端部停止自由活塞。

Abstract: A shock absorber includes: a cylinder; a piston that is movably inserted into the cylinder and defines an extension side chamber and a compression side chamber inside the cylinder; an extension side damping passage and a compression side damping passage that communicate the extension side chamber with the compression side chamber; a pressure chamber that communicates with the extension side chamber and the compression side chamber; and an elastic member that defines a first chamber communicating with the extension side chamber and a second chamber communicating with the compression side chamber inside the pressure chamber.

Abstract: A shock absorber includes a housing that includes an annular nut portion threaded to an outer circumference of a front end portion of a piston rod, an annular flange portion protruding outward from the nut portion, and a tubular portion extending from an outer circumference of the flange portion in a direction away from the piston rod, a tube that is inserted into the housing, and an elastic member that is attached to an inner circumference of the tube to define a first chamber communicating with an extension side chamber and a second chamber communicating with a compression side chamber inside the housing and the tube is fixed while being sandwiched between the flange portion and a bent portion corresponding to a support portion formed by caulking a front end of the tubular portion inward.
