A shock absorber (D1) with a vehicle height adjustment function according to the present invention is provided with: a shock absorber body (1) having a cylinder (2) filled with a liquid, a piston (3) that divides the inside of the cylinder (2) into an extension-side chamber (R1) and a compression-side chamber (R2), and a piston rod (4) connected to the piston (3); a suspension spring (S) that biases the damper main body (1) in the extension direction; the liquid storage chamber (R) is used for storing liquid; a damper circuit (C1) that is connected to the extension-side chamber (R1), the compression-side chamber (R2), and the liquid storage chamber (R), and that causes the damper main body (1) to generate a damping force when the damper main body (1) expands and contracts; a pump (P) that can draw in and discharge the liquid from the liquid reservoir (R); and a switching valve (V1) that is provided between the damper main body (1) and the damper circuit (C1) and between the damper main body (1) and the pump (P), and that can switch between a damper mode in which the damper main body (1) and the damper circuit (C1) are connected to cause the damper main body (1) to generate a damping force, and a vehicle height adjustment mode in which the damper main body (1) and the pump (P) are connected.

    本发明中的带有车辆高度调节功能的缓冲器(D1)具备:缓冲器主体(1),所述缓冲器主体(1)具有填充有液体的气缸(2)、将气缸(2)内分隔为伸长侧腔室(R1)和压缩侧腔室(R2)的活塞(3)、与活塞(3)相连结的活塞杆(4);悬架弹簧(S),所述悬架弹簧(S)沿伸长方向对缓冲器主体(1)施力;储液室(R),所述储液室(R)储存液体;减震器回路(C1),所述减震器回路(C1)与伸长侧腔室(R1)、压缩侧腔室(R2)以及储液室(R)连接,在缓冲器主体(1)伸缩时使缓冲器主体(1)产生阻尼力;泵(P),所述泵(P)可从储液室(R)吸入液体并吐出;切换阀(V1),所述切换阀(V1)设置在缓冲器主体(1)与减震器回路(C1)以及泵(P)之间,并可切换将缓冲器主体(1)与减震器回路(C1)连接来使缓冲器主体(1)产生阻尼力的减震器模式、以及将缓冲器主体(1)与泵(P)连接的车辆高度调节模式。
