Abstract

Die Vorrichtung (13) betrifft ein Mittel zur Verhinderung des Rückflusses von verschmutztem Wasser ins Trinkwasser-Leitungssystem. Eine hochelastische kreisringförmige Membran (19), welche an ihrer Peripherie in einem Ventilgehäuse (21) festgehalten wird, verschliesst die Einlauföffnungen (39), wenn im Leitungssystem ein Vakuum entsteht.
