Description

Die meisten Druckerzeuger für hydraulisehe Anlagern arbeiten mdit,drei oder mehr Ventilen. Bei der Erfindung handelt es sich um einen Druckerzeuger einfachster Bauart, der in vielen Fällen den gestellten Aufgaben enspricht. Er ist dadurch ausgezeichnet, daß ein zwischen Nachlaufbehälter und Druckzylinder eingebautes an sich bekanntes Saugventil in Verbindüng mit einer Drossel (kein Ventil) Verwendung findet, die den, Leitungen zu den Arbeitsstellen vorgeschaltet ist. Diese Drossel behindert den Flüssigkeitsstrom in Richtung zu den Arbeitszylindern in keiner Weise. Das Rückfließen der Flüssigkeit in den Drudkerzendger ist jedoch von dem hierzu vorhandenen kleinen Loch in einer beweglichen Gummiplatte abhängig. Dadurch entsteht nach dem Arbeitshub beim Zurückgehen des Druckkolbens in Ruhestellung ein verhältnismäßig starker Unterdruck, so daß sich das Saugventil sehr leicht öffnet. Hierbei strömt Flüssigeit aus dem Nachlaufbehälter in den Druckerzeuger, bevor, behindert durch die Drossel, das gesamte Volumen der zu den Arbeitsstellen gedrückten Flüssigkeit nach dem Arbeitshub in den Druckerzeuger zurückgeflossen ist. Es entsteht im Druckerzeuger kein Unterdruck, auch wenn der Kolben schnell hin und her bewegt wird. Der Druckzylinder ist immer vollständig mit Flüssigkeit gefüllt, ohne Luft und hat daher keinen Leerlauf. Die zuviel angesaugte Flüssigkeit fließt durch die vor dem Kolben befindliche Bohrung in bekannter Weist wieder in den Nachlaufbehälter zurück.Most of the pressure generators for hydraulic systems work with three or more valves. The invention is a very simple pressure generator Design that in many cases corresponds to the tasks set. He is distinguished by that a built-in between the follow-up container and pressure cylinder, known per se Suction valve in connection with a throttle (no valve) is used, which the, lines to the workplaces is connected upstream. This choke hinders the flow of liquid in the direction of the working cylinders in no way. The reflux the liquid in the Drudkerzendger, however, is of the small size available for this purpose Hole in a movable rubber plate dependent. This creates after the working stroke when the pressure piston goes back into the rest position, a relatively strong negative pressure, so that the suction valve opens very easily. In this case, liquid flows out of the After-flow tank in the pressure generator, before, hindered by the throttle, the entire Volume of the liquid pressed to the work sites after the work stroke in the pressure generator has flowed back. There is no negative pressure in the pressure generator, even if the piston is moved back and forth quickly. The pressure cylinder is always completely filled with liquid, without air and therefore has no idle. the Too much liquid that has been sucked in flows through the bore in front of the piston in the known way back into the follow-up container.

Weitere Merkmale der Erfindung sind aus der nachstehenden Bieschreibung und aus oder Zeichnung ersichtlich. In ihr ist ein Ausführungsbeispiel veranschaulicht.Further features of the invention are evident from the description below and can be seen from or drawing. An exemplary embodiment is illustrated in it.

In der Zeichnung ist der Druckzylinder mit I bezeichnet und der Nachlaufbehälter mit 2. Zwischen Nachlaufdbehälter und Druckzylinder befindet sich in bekannter Weise ein Saugventil 3. Den Leitungen 4, die zu den Arbeitsstellen führen, ist eine Drosseleinrichtung vorgeschaltet. Sie besteht z. B. aus der mit der Bohrung Io versehenen Gummiplatte 6, die durch die Feder 8 auf ihren Sitz gedrückt wird.In the drawing, the pressure cylinder is denoted by I and the follow-up container with 2. There is a known way between Nachlaufdbehälter and pressure cylinder a suction valve 3. There is a throttle device on the lines 4 that lead to the work stations upstream. It consists z. B. from the rubber plate provided with the hole Io 6, which is pressed onto its seat by the spring 8.
