Description
Claims (5)
- 航空機の着陸装置用の緩衝装置であって、該緩衝装置が、一方が他方の中に伸縮自在にスライドするように取り付けられた2つの要素(1,2)を有すると共に油圧油及びガスで充填された内部ボリュームを画成し、該内部ボリュームが、少なくとも1つの絞りオリフィス(10)を有する隔壁(5)によって少なくとも2つのチャンバー(7,8)に分割され、油圧油が、特に、当該緩衝装置の圧縮中に、前記絞りオリフィスを介して一方のチャンバーから他方のチャンバーへ通過する緩衝装置において、前記隔壁が、着陸装置が展開位置にあるときに、ガスが一方のチャンバーから他方のチャンバーへ移動できるようにするための少なくとも1つのガス抜きオリフィスを有し、該ガス抜きオリフィスが、着陸装置が展開位置にあるときに、前記絞りオリフィスの上方に位置するように、前記絞りオリフィスに対して鉛直にオフセットしていることを特徴とする緩衝装置。
- 前記ガス抜きオリフィスが、前記隔壁によって支持され、前記隔壁(5)の下方にある前記チャンバー(7)内へ開放する中空の柱(20)の頂端に設けられることを特徴とする請求項1に記載の緩衝装置。
- 前記柱が、前記隔壁(5)に取り付けられ、且つ、前記隔壁の絞りオリフィス(10)と協働するスライド可能に取り付けられたバルブ部材(12)を保持するカラー(24)を有することを特徴とする請求項2に記載の緩衝装置。
- 前記柱が、前記隔壁にねじ止めされていることを特徴とする請求項3に記載の緩衝装置。
- 前記隔壁の下方に延びる前記チャンバーが油圧油で完全に充填されるときでさえ、前記ガス抜きオリフィスが、油圧油に漬かったままとなる高さにあることを特徴とする請求項1に記載の緩衝装置。
