Description
R1・・・伸側室、R2・・・圧側室、V・・・減衰弁、VH・・・高圧力損失弁、VL・・・低圧力損失弁
Claims (5)
- 上流の圧力により開閉し、開弁時に上流から下流への液体の流れを許容する低圧力損失弁と、
前記低圧力損失弁と並列に設けられて、前記低圧力損失弁に比較して同流量の液体の通過時における圧力損失が大きいノーマルクローズ型の高圧力損失弁とを備え、
前記低圧力損失弁は、上流の圧力の上昇に伴って閉弁する
ことを特徴とする減衰弁。 - 前記高圧力損失弁は、前記低圧力損失弁の閉弁とともに開弁する
ことを特徴とする請求項1に記載の減衰弁。 - 前記高圧力損失弁は、開弁圧が前記低圧力損失弁の開弁圧よりも高く、前記低圧力損失弁の閉弁圧よりも低い圧力に設定され、前記低圧力損失弁が閉弁するより前に開弁する
ことを特徴とする請求項1に記載の減衰弁。 - 前記高圧力損失弁は、前記低圧力損失弁の閉弁の際に、前記低圧力損失弁を通過していた流量を補償する
ことを特徴とする請求項1から3のいずれか一項に記載の減衰弁。 - シリンダと、
シリンダ内に移動自在に挿入されたピストンと、
前記シリンダ内に前記ピストンで区画した伸側室と圧側室と、
リザーバと、
前記伸側室と前記圧側室との間、前記伸側室と前記リザーバとの間、および、前記圧側室と前記リザーバとの間のうち、任意の箇所に設けた請求項1から4のいずれか一項に記載の減衰弁とを備えた
ことを特徴とするダンパ。
