- シリンダと、
前記シリンダ内に摺動自在に挿入されて前記シリンダ内を伸側室と圧側室とに区画するピストンと、
前記シリンダに挿入されるとともに前記ピストンに連結されるロッドと、
前記伸側室から前記圧側室へ向かう液体の流れのみを許容する伸側通路と、
前記圧側室から前記伸側室へ向かう液体の流れのみを許容する圧側通路と、
リザーバと、
前記圧側室から前記リザーバへ向かう液体の流れのみを許容する排出通路と、
前記伸側通路、前記圧側通路および前記排出通路のそれぞれに設けられる絞り弁および低圧リリーフ弁と、
前記絞り弁および前記低圧リリーフ弁に並列されて前記低圧リリーフ弁よりも高い開弁圧で開弁する高圧リリーフ弁とを備え、
前記シリンダに対する前記ピストンの速度であるピストン速度が低速域にあっては前記低圧リリーフ弁によって低減衰力を出力し、前記ピストン速度が高速域にあっては前記高圧リリーフ弁によって高減衰力を出力し、前記ピストン速度が前記低速域と前記高速域の間の中速域では、前記絞り弁によって前記低速域および前記高速域よりも大きな減衰係数で前記ピストン速度の増加に応じて低減衰力から高減衰力へ減衰力を増加させる減衰力特性を有する
ことを特徴とする免震用ダンパ。 - 前記ピストン速度における前記低速域と前記中速域の境を60cm/sとし、前記中速域と前記高速域の境を90cm/sとする
ことを特徴とする請求項1に記載の免震用ダンパ。
