Claims (1)
- 磁性体粒子を含む磁気粘性流体を満たしたシリンダ(21)の内部をピストン(22)で第1流体室(25)および第2流体室(26)に区画し、ピストン(22)を貫通するように形成した流体通路(22a)で前記第1流体室(25)および第2流体室(26)を相互に連通させ、ピストン(22)に設けたコイル(28)に通電して流体通路(22a)中の磁気粘性流体の粘性を変化させて減衰力を制御する可変減衰力ダンパーにおいて、
停止状態にあった車両を走行させる場合に、走行中の車両の運動状態に関わらずに且つシリンダ(21)内でのピストン(22)の上昇時にだけ所定値以上の電流をコイル(28)に供給することを特徴とする、可変減衰力ダンパー。
