摘要： A twin-tube shock absorber comprising an outer tube which houses an inner tube. The inner tube forms an annulus area between the outer tube and the inner tube, and includes a check valve for allowing a fluid to flow unidirectionally from the annulus area to the interior volume of the inner tube. The shock absorber includes a piston which is slidably disposed within the inner tube and divides the interior volume into a rod side chamber and a cap side chamber. The piston includes a check valve allowing the fluid to flow unidirectionally from the cap side chamber to the rod side chamber. A flow regulator is disposed about the inner tube for allowing the unidirectional flow of fluid from the rod side chamber to the annulus area, wherein the flow regulator provides a resistance against the flow of the fluid from the rod side chamber to the annulus area.

摘要： A shock absorber includes a suction passage (3) configured to permit only a flow from a reservoir (R) toward a compression-side chamber (R2), a rectification passage (4) configured to permit only a flow from the compression-side chamber (R2) toward a extension-side chamber (R1), and a variable valve (V) configured to permit only a flow from the extension-side chamber (R1) toward the reservoir (R). A large chamber (16) serving as a compression-side pressure chamber that communicates with the compression-side chamber (R2) and an outer periphery chamber (17) serving as a extension-side pressure chamber that communicates with the extension-side chamber (R1) are partitioned in the shock absorber by a free piston (5) that moves slidably within a bottom member (11) serving as a housing. A compression-side pressure-receiving area (A1) of the free piston (5) is larger than an extension-side pressure-receiving area (B1). Therefore, even in the uniflow shock absorber in which the extension-side chamber (R1) and the compression-side chamber (R2) are at equal pressures during the contraction operation, the damping force is reduced under conditions in which high frequency is input since the free piston (5) moves downward.

摘要： 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 (E) that communicates with an expansion-side chamber and a contraction-side chamber, and an expansion-side free piston (15) that partitions the expansion-side actuating chamber into a first expansion-side pressure chamber (E1) and a second expansion-side pressure chamber (E2). The contraction-side sensitive unit has a contraction-side actuating chamber (C) that communicates with a contraction-side chamber and a reservoir (R), and a contraction-side free piston (24) that partitions the contraction-side actuating chamber into a first contraction-side pressure chamber (C1) and a second contraction-side pressure chamber (C2).

The piston part is provided with an extension damping valve for generating an extension damping force, the extension damping valve being configured to permit a working fluid flowing from the first chamber toward the second chamber to flow only in a single direction. The base valve part is provided with a compression damping valve for generating a compression damping force, the compression damping valve being configured to permit a working fluid flowing from the second chamber toward the cap-part side of the base valve part to flow only in a single direction. A first check valve is not provided in the piston part but provided outside the internal space of the cylinder body, the first check valve being configured to permit a working fluid flowing into the first chamber in a compression stroke to flow only in a single direction. A second check valve is provided in at least one of the base valve part and the outside of the internal space of the cylinder body, the second check valve being configured to permit a working fluid flowing into the second chamber in an extension stroke to flow only in a single direction.
