Claims (2)

1. Druckentlastungsvorrichtung, die auf einem Tank montierbar ist, der in einer Stirnwand eine Öffnung aufweist, welche Vorrichtung einen die Öffnung umgebenden Ring enthält, der eine Dichtung aus elastischem Material in einer Umfangsnut in seinem Aussenumfang aufweist, und ein becherförmiges Ventilverschlussteil, das mit seinem Platten-Teil auf der Aussenstirnfläche des Ringes unter Zwischenschaltung eines Dichtungsringes zwischen diesen Teilen in der Schliessposition des Schliessteils abgedichtet abstützbar ist, wobei ein Umfangsflanschteil des Schliessteils den Ring umgreift und mit der Dichtung in dem Aussenumfang des Ringes abdichtend zusammenwirkt, welche für den Streifkontakt mit einer Innenfläche des Flanschteils angeordnet ist, wobei das Ventilverschlussteil von Federmitteln in seine Schliesstellung gedrückt wird, dadurch gekennzeichnet, dass die Dichtung in dem Aussenumfang des Ringes einen flachen Querschnitt hat, wobei die Umfangsnut und der Flanschteil derart angeordnet sind, dass die Dichtung ausgelenkt ist, wenn das Ventilverschlussteil sich in seiner Schliessstellung befindet, derart, dass die Auslenkung der Dichtung sich im wesentlichen über die gesamte radiale Breite erstreckt, und die Dichtung nicht ausgelenkt ist, wenn das Ventilverschlussteil sich in seiner geöffneten Position befindet.
2. Druckentlastungsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Weite des inneren Bereichs der Umfangsnut zur Aufnahme der Dichtung in dem Aussenumfang des Ringes im wesentlichen der Dicke der Dichtung entspricht und die Weite des Aussenbereichs der Nut grösserals die Dicke der Dichtung ist.
