Claims (5)
- シリンダチューブ内を摺動するピストンの下側の駆動室への作動流体の供給に応じて上方に伸長するとともに、前記ピストンが伸側のストローク端に達する前に伸長作動を抑制するクッション機能を有する単動型の流体圧シリンダであって、
前記ピストンの上部に連結されて前記ピストンとの間にロッド内室を画成するピストンロッドと、
前記ピストンロッドと前記シリンダチューブとの間に画成され、前記流体圧シリンダの伸長に応じて容積が減少するクッション室と、
前記ピストンロッドに形成され前記クッション室と前記ロッド内室とを連通する連通路と、
前記連通路より下方に形成され前記クッション室から前記ロッド内室への作動流体の流れに抵抗を与えることで前記クッション機能を発揮する絞り通路と、
前記ピストンに設けられ前記ロッド内室と前記駆動室とを連通するとともに前記ロッド内室から前記駆動室への作動流体の流れのみを許容する逆止機能を有する逆止弁と、
前記ピストンに形成され前記クッション室の圧力をパイロット圧として前記逆止弁に導くことで逆止機能を解除させるパイロット通路と、
を備えることを特徴とする流体圧シリンダ。 - 前記ロッド内室に収容され前記ロッド内室を作動流体とエアとに隔てるとともに前記ロッド内室の作動流体圧に応じてエアの体積を増減させる隔離部材をさらに備える、
ことを特徴とする請求項1に記載の流体圧シリンダ。 - 前記隔離部材は、前記ロッド内室を上下に摺動可能であって上方にエアを蓄えるフリーピストンである、
ことを特徴とする請求項2に記載の流体圧シリンダ。 - 前記隔離部材は、内部にエアを蓄える膨縮可能なブーツである、
ことを特徴とする請求項2に記載の流体圧シリンダ。 - 前記ロッド内室の容積は、前記流体圧シリンダの最収縮時における前記クッション室の容積以上である、
ことを特徴とする請求項1から請求項4までのいずれか一項に記載の流体圧シリンダ。
