- 油圧アキュムレータにおける水撃減衰装置であって、
この装置は、前記アキュムレータの構成要素であり、前記アキュムレータ内部の部分(12)と、前記アキュムレータが接続する、油圧系統(14)との間に形成される流体の流れに対して絞りとして作用しており、
前記絞りは、弁構成要素(16)における断面積を減少させることができる少なくとも一つの流通領域(24)から形成され、前記弁構成要素(16)は、その弁位置の一つにあるときは、前記流体の流れを前記それぞれの流通領域(24)により絞り、その別の弁位置にあるときは、基本的に前記流れを解放しており、
前記それぞれの流通領域(24)は、その自由端の少なくとも一つにおいて漏斗状拡張部(26;28)が設けられており、
前記拡張部(26;28)は、前記アキュムレータの内部(12)の方向または、前記油圧系統(14)の方向に向けられる、水撃減衰装置において、
前記弁構成要素(16)は、その端の一つにおいて橋状の伸張部(30)を有する弁ピストンとして構成される、ことを特徴とする減衰装置。 - 前記それぞれの流通領域(24)は、前記弁構成要素(16)において中央管路の形であり、
前記漏斗状拡張部(26;28)は前記中央管路の両端に設けられる、
ことを特徴とする請求項1に記載の減衰装置。 - 前記弁構成要素(16)は、弁ハウジング(18)に沿うように形成される、円筒形案内面(34)を、外周側に具備しており、前記弁構成要素(16)が、前記アキュムレータのハウジング(10)の一端に配置されることを特徴とする請求項1または2に記載の減衰装置。
- 前記弁構成要素(16)は、前記外周側において及び前記橋状の伸張部(30)の間に、水平面(44)を具備しており、前記水平面(44)は、前記弁ハウジング(18)の円筒形内周面(36)と共に、流体出口(46)を画定することを特徴とする請求項3に記載の減衰装置。
- 前記弁構成要素(16)は、その端部側に水平密封面(38,40)を具備しており、前記弁構成要素(16)は、前記水平密封面(38)が前記弁ハウジング(18)の水平接触面(42)と接触できる方向、または前記橋状の伸張部(30)が前記弁ハウジング(18)の前記水平接触面(42)に接触できる方向で、前記弁ハウジング(18)に配置される、ことを特徴とする請求項3または4に記載の減衰装置。
- 前記流通領域(24)を有する前記弁構成要素(16)の部分的構造長は、前記橋状の伸張部(30)を有する前記弁構成要素(16)の全体構造長の半分を超えることを特徴とする請求項1から5のいずれか一つに記載の減衰装置。
- 前記弁構成要素(16)は、前記漏斗状拡張部(26,28)によって、水平密封面(38,40)において開口することを特徴とする請求項2から6のいずれか一つに記載の減衰装置。
- 前記弁ハウジング(18)は、前記外周側において、前記アキュムレータハウジング(10)の部分に固定するためのネジ山(20)を具備することを特徴とする請求項3から7のいずれか一つに記載の減衰装置。
