- 第1のシステムから第2のシステムへの媒体の流れを制御する弁であって、
貯槽を形成し且つ流路開口を含む、変形可能なドーム形状の構造と、
当該弁を前記第1のシステムに接続する第1のコネクタ開口と、前記流路開口を開閉するよう前記流路開口と相互作用する接触要素とを含む、弁カバーと、
該弁カバーに並びに前記変形可能なドーム形状の構造に気密に接続され、当該弁を前記第2のシステムに接続する第2のコネクタ開口を含み、且つ前記貯槽に連結される、弁ベースとを含み、
前記変形可能なドーム形状の構造は、
当該弁の開放状態において、前記変形可能なドーム形状の構造が変形させられ、前記流路開口が前記接触要素に接続されないで、媒体が前記第1及び第2のコネクタ開口並びに前記流路開口を通じて前記第1のシステムから前記第2のシステムに流れるのを可能にし、且つ
当該弁の閉塞状態において、前記変形可能なドーム形状の構造がその本来のドーム形状にあり、前記流路開口が前記接触要素に接続され、故に、閉塞されるように構成される、
弁。 - 前記第1のシステムと前記第2のシステムとの間の圧力差が圧力解放閾値より上であるならば、前記変形可能なドーム形状の構造は変形させられ、前記流路開口は前記接触要素に接続されず、
前記第1のシステムと前記第2のシステムとの間の圧力差が圧力維持閾値より下であるならば、前記変形可能なドーム形状の構造はその本来の形状にあり、前記流路開口は前記接触要素と接触する、
請求項1に記載の弁。 - 前記第1のシステムと前記第2のシステムとの間の圧力差が圧力解放閾値を超えるとき、前記変形可能なドーム形状の構造は変形させられ、前記流路開口は前記接触要素から切り離され、
前記第1のシステムと前記第2のシステムとの間の圧力差が圧力維持閾値よりも下に降下するとき、前記変形可能なドーム形状の構造はその本来のドーム形状を取り戻し、前記流路開口は前記接触要素と接触する、
請求項1に記載の弁。 - 前記圧力解放閾値は、前記圧力維持閾値よりも高く、当該弁は、切換えヒステリシスをもたらすように構成される、請求項3に記載の弁。
