Abstract

Modifiziertes Hydraulisches-Drei-Kammer-Systemtrenngerät (BA), bei dem die vordruckseitige Rückflußverhinderung (P1 > Pi) und das Entlastungsventil zur Entleerung der Mittelzone (Pi), entgegen, wie bei den konventionellen BA-Geräten, dem Vordruck (P1) gegenüberliegend nicht mit Mitteldruck (Pi), sondern mit dem Druck hinter dem hinterdruckseitigen Rückflußverhinderer (34, 35, 36)(P2) beauflagt und hierbei sowohl der Dichtkegel (15) der vordruckseitigen Rückflußverhinderung (14, 15, 16, 17, 18, 20, 27, 23, 19) als auch der Dichtkegel (46) des Entlastungsventiles (46, 42, 48, 45, 47, 51, 50, 63, 49) gegenüber dem Druck (Pi) in der Mittelzone (4, 5, 21, 41) hydraulisch ausgeglichen sind. Es werden sowohl auf die vordruckseitige Rückflußverhinderung als auch auf das Entlastungsventil vom Mitteldruck (Pi) weder öffnende noch schließende Kräfte ausgeübt.
Das modifizierte Systemtrenngerät (BA) ist bei auftretendem Rückdruck, bei dichtem hinterdruckseitigen Rückflußverhinderer "selbstumschaltend".
Mit dem Gerät können z. B. hydraulische Badewannen-Lifter abgesichert werden.
