Abstract

The infinitely adjustable tandem cylinder arrangement is for precise metering of fluids and has a hydraulically operated adjuster piston which is controlled by the fluid being metered and is without external mechanical parts of any kind. The fluid entering the filling space in response to this piston movement displaces the sealing piston within the fill space and switches over the attendant inlet and outlet valves in the metering circuit. The adjuster piston which initiates the metering action should be adjustable in stroke by means of a fitted spindle, thus providing differential metering to suit the duty or container capacity, ratios. This adjustment can be achieved whilst the circuit is operating.

Description

Stufenlos einstellbarer TANDEM-Zylindei zum genauen Dosieren von Flüssigkeiten.Infinitely adjustable TANDEM cylinder for precise dosing of Liquids.

System;System;

Eine unter Druck stehende Flüssigkeit wird durch das Zulaufventil 2 und durch den Stellkolben -D- in den Füllraum B gedrückt. Der Kolben -C-schiebt sich durch den Druck nach links bis zum Kolbenboden -F-. Die im Füllraum A befindliche Luft wird durch das Ablaufventil 2 abgeleitet. Wenn der Kolben -C- am Zylinderdeckel -F- anschlägt, schließen sich die Zu- und Ablaufventile 2 und es werden die Zu- und Ablaufventile 1 geöffnet. Die unter Druck stehende Flüssigkeit gelangt nun über das Zulaufventil 1 durch den Zylinderdeckel -F- in den Füllraum A und schiebt den Kolben -C- nach rechts bis zum Stellkolben -D-* Da der Füllraum B mit der Flüssigkeit gefüllt war, gelangt diese durch den Stellkolben -D- über das Ablaufventil 1 zu dem Abfüllbehälter A. Wenn der Kolben -C- am Stellkolben D anschlägt, werden die Zu- und Ablaufventile 1 geschlossen und die Füllung ist beendet. Es kann jetzt sofort wieder eine neue Füllung durch das öffnen der Zu- und Ablaufventile 2 erfolgen.A pressurized liquid is through the inlet valve 2 and pressed into filling chamber B by actuating piston -D-. The pressure causes piston -C- to slide to the left as far as piston crown -F-. The in The air in filling chamber A is diverted through the drain valve 2. When the piston -C- hits the cylinder cover -F-, the closures and Drain valves 2 and the inlet and outlet valves 1 are opened. The pressurized liquid now passes through the inlet valve 1 the cylinder cover -F- into the filling chamber A and pushes the piston -C- to the right as far as the setting piston -D- * Since the filling chamber B is filled with the liquid it reaches the filling container A through the setting piston -D- via the drain valve 1. When the piston -C- strikes the setting piston D, the inlet and outlet valves 1 are closed and filling is completed. A new filling can now be made immediately by opening the inlet and outlet Drain valves 2 take place.

Die stufenlose Einstellung der Füllmenge erfolgt durch das Verschieben des Stellkolben -C- mit der Spindel -E- .The infinitely variable setting of the filling quantity is carried out by moving the Adjusting piston -C- with spindle -E-.

Vorteile des Systems;Advantages of the system;

Da der Kolben -C- hydraulich durch den Druck des Füllmediums verschoben wird, besitzt dieses System außer den pneumatisch gesteuerten Kugelhähnen keine bewegten Teile. Es ist möglich, je nach Wahl des Meßzylinders, Ge binde von 1 ecm bis 200 1 mit einem Hub abzufüllen.Since the piston -C- shifted hydraulically by the pressure of the filling medium apart from the pneumatically controlled ball valves, this system has no moving parts. It is possible, depending on the choice of the measuring cylinder, Ge binding to fill from 1 ecm to 200 1 with one stroke.

Da der Ansaughub (normaler Messkolbenfüller) entfällt, können die Füllungen direkt aufeinander erfolgen. Es kann kein Saugvakuum entstehen. Außerdem wirkt sich das Undichtwerden des Kolbens -C- nicht auf die Füllgenauigkeit aus, wenn sie mit dem Kolben -D- durch die Spindel -E- ausgeglichen wurde. Die Mengenverstellung kann während des Füllvorganges stufenlos eingestellt werden. Die Füllzeitregelung erfolgt stufenlos durch Drosselung der Zulaufmenge.Since there is no suction stroke (normal volumetric flask filler), the fillings can be made directly on top of one another. There can be no suction vacuum. In addition, the leakage of the piston -C- does not affect the filling accuracy when it is with the piston -D- through the Spindle -E- has been compensated. The quantity adjustment can be continuously adjusted during the filling process. The filling time control occurs steplessly by throttling the inflow volume.
