Abstract

Um ein einfaches und sicheres Reversieren einer Pumpenanordnung zu ermöglichen, wird zur Rückführung des Volumenstromes oftmals ein Und-Ventil zwischen den beiden Verbraucherleitungen geschaltet. Dies kann jedoch zu einem hydraulischen Kurzschluss über das Und-Venil führen, wenn der Druck in den Leitungen nicht rasch genug abgebaut werden kann, wodurch eine sichere Reversierung nicht immer möglich ist. Dieses Problem wird durch die gegenständliche Erfindung behoben, indem zu jeder Pumpe ein entsperrbares Rückschlagventil 4, 5 angeordnet wird, das durch die zugehörige Pumpe 2, 3 betätigt wird.
