Abstract: A suspension device includes: a damper that has an extension-side chamber and a contraction-side chamber; an extension-side passage connected to the extension-side chamber; a contraction-side passage connected to the contraction-side chamber; a switching device that connects one of the extension-side passage and the contraction-side passage to the supply passage and connecting the other of the extension-side passage and the contraction-side passage to the discharge passage selectively; an extension-side damping element provided in the extension-side passage; a contraction-side damping element provided in the contraction-side passage; a control valve capable of adjusting a pressure in the supply passage; an intake check valve provided midway in the intake passage; and a supply-side check valve provided in the supply passage between the control valve and the pump.

Abstract: A shock absorber includes at least one of an expansion-side sensitive unit and a contraction-side sensitive unit. The expansion-side sensitive unit has an expansion-side actuating chamber that communicates with an expansion-side chamber and a contraction-side chamber, and an expansion-side free piston that partitions the expansion-side actuating chamber into a first expansion-side pressure chamber and a second expansion-side pressure chamber. The contraction-side sensitive unit has a contraction-side actuating chamber that communicates with a contraction-side chamber and a reservoir, and a contraction-side free piston that partitions the contraction-side actuating chamber into a first contraction-side pressure chamber and a second contraction-side pressure chamber.

Abstract translation: 减震器包括膨胀侧敏感单元和收缩侧敏感单元中的至少一个。 膨胀侧敏感单元具有膨胀侧致动室，其与膨胀侧室和收缩侧室连通，以及膨胀侧自由活塞，其将膨胀侧致动室分隔成第一膨胀侧压力 室和第二膨胀侧压力室。 收缩侧敏感单元具有收缩侧致动室，其与收缩侧室和储存器连通，以及收缩侧自由活塞，其将收缩侧致动室分隔成第一收缩侧压力室和 第二收缩侧压力室。
