- 可撓性を有する板状の弁体が収納される弁室と、前記弁室の天面に開口し液体が導入される導入口と、前記弁室の底面に開口し液体が導出される導出口とを備え、
前記弁体は、外郭縁が前記弁室の側壁とは間隔を存して設けられ、前記弁室の底面側から突出する複数の突起によりその外郭縁よりも内側が支持されて、無圧状態では前記外郭縁が前記弁室の天面に液密に当接し、前記導入口から導入される液体により圧力がかけられた状態では前記外郭縁全体が前記弁室の天面から離反するように前記弁室内に保持され、
前記外郭縁が前記弁室の天面に向けて突出した円錐円板形状を有し、前記弁室の天面と前記突起との間に挟持され自己の弾性によって前記外郭縁が前記弁室の天面に付勢されていることを特徴とする液体流路の弁構造。
