Abstract
Description
本発明の1つの実現は、制御可能な振動ダンパの逆止弁における提案されたバネの使用に関する。
図3Aには、組み立てられた状態における逆止弁40の一実施形態例が、断面図により示される。図3Bには、図3Aに詳細に示されたXの拡大が示される。逆止弁40は、基体42と閉鎖体44とを備える。基体42は、長手方向弁軸Aと、第1チャネル46および複数の第2チャネル48とを形成する。第1チャネル46は長手方向弁軸Aに沿って延び、一方、第2チャネル48は第1チャネル46に対し垂直に延びる。第2チャネル48は、長手方向弁軸Aに沿って(図3Aの提示を参照して右に向かって)部分的に開く。第2チャネル48は、閉鎖体44が基体42へと着座した後、結果的に完全に閉止されるに過ぎない。したがって、閉鎖体44は、封止下において基体42へと着座する必要があり、これは、例えば、図示されないOリングを用いるか圧入によって行われることが可能である。
