To provide an oil damper system which enables improvement of maintainability of an oil damper whose damping performance is changed.SOLUTION: A damping valve unit 10 is provided at a uniflow type cylinder unit, has a valve body 14 which is biased by a pressure-adjusting spring 16, and is configured to absorb energy through action in which a working fluid F flowing from a working fluid outflow chamber of the cylinder unit to an outer cylinder moves the valve body against a spring force. The pressure-adjusting spring of the damping valve unit is formed as return means which returns a control oil f to control cylinder units so that control piston rods are respectively returned to initial positions.SELECTED DRAWING: Figure 4 【課題】減衰性能を変化させるようにしたオイルダンパを対象として、メンテナンス性を向上することが可能なオイルダンパシステムを提供する。【解決手段】ユニフロー型のシリンダユニットに設けられる減衰バルブユニット１０は、調圧バネ１６で付勢される弁体１４を有し、シリンダユニットの作動油流出室から外側シリンダへ流れる作動油Ｆがバネ力に抗して弁体を移動させる作用でエネルギ吸収するように構成され、この減衰バルブユニットの調圧バネは、制御用ピストンロッドそれぞれを初期位置に復帰させるために、制御用油ｆを制御用シリンダユニットそれぞれへ戻す戻し手段として構成される。【選択図】図４
