Abstract

Ein Systemtrenner zum physischen Trennen eines stromaufwärtigen Flüssigkeitssystems von einem stromabwärtigen Flüssigkeitssystem mittels eines Ablassventils (34) in Abhängigkeit vom Druckgefälle zwischen stromaufwärtigem und stromabwärtigem Flüssigkeitssystem, mit einem stromaufwärtigen Rückflussverhinderer (40), einem stromabwärtigen Rückflussverhinderer (64) und einem als Kolben ausgebildeten Ablassventilkörper (18), der strömungsmäßig zwischen den Rückflussverhinderern (40, 64) angeordnet ist, wobei stromaufwärts von dem stromaufwärtigen Rückflussverhinderer (40) ein Eingangsdruck des stromaufwärtigen Flüssigkeitssystems, zwischen dem Ablassventilkörper (18) und dem stromabwärtigen Rückflußverhinderer (64) ein Mitteldruck in einem Mitteldruckraum (66) und stromabwärts von dem stromabwärtigen Rückflußverhinderer (64) ein Ausgangsdruck des stromabwärtigen Flüssigkcitssystcms herrscht, und wobei an dem Ablassvcntilkörper (18) die Druckdifferenz zwischen Eingangsdruck und Mitteldruck in Schließrichtung einer in Öffnungsrichtung auf den Ablassventilkörper wirkenden Belastungsfeder (60) entgegenwirkt, wobei der Ablassventilkörper (18) auf der stromabwärtigen Seite eine verringerte Fläche (d) aufweist, die kleiner ist, als die für den Eingangsdruck wirksame Andruckfläche, wodurch von dem Ablassventilkörper ein Hohlraum (74) gebildet wird, und der Hohlraum mit dem Mitteldruckraum (66) in Verbindung steht, ist dadurch gekennzeichnet, dass ein in Bewegungsrichtung des Ablassventilkörpers beweglicher Schiebesitz (76) in dem Hohlraum (74) vorgesehen ist, der gegenüber dem Ablassventilkörper bis zu einem gehäusefesten Anschlag (84) beweglich ist, welcher in Strömungsrichtung vor dem Ventilsitz (32) des Ablassventils (34) angeordnet ist.
