Description

Es ist aus Zweckmäßigkeitsgründen erwünscht, daß die Flüssigkeit einer Druckleitungsanlage auch in Ruhestellung des Druckerzeugers bereits unter einem gewissen Vordruck steht. Dieser Vordruck ist in der Regel nur etwas größer als das Gewicht der Flüssigkeitssäule zwischen Druckerzeuger und Nachlaufbehälter zuzüglich dem atmosphärischen Druck. Um diese Vorspannung zu erzeugen, wurden bisher federbelastete Ventile, federbelastete Druckspeicher, Druckluft usw. vorgeschlagen.For convenience, it is desirable that the liquid be one Pressure line system even when the pressure generator is in the idle position under one certain form is available. This form is usually only slightly larger than that Plus the weight of the liquid column between the pressure generator and the follow-up tank the atmospheric pressure. In order to generate this preload, spring-loaded ones were previously used Valves, spring-loaded accumulators, compressed air, etc. proposed.

Bei der Erfindung fallen alle diese vielteiligen Zusätze für Druckzylinder, insbesondere für hydraulische Fernbetätigungen, weg. Erfindungsgemäß wird lediglich über die feine Ausgleichsbohrung, die vom Druckkolben gesteuert wird, eine Abdeckplatte z. B. aus Gummi gelegt, die im Durchmesser erheblich größer ist als der Querschnitt der Ausgleichsbohrung und auf welche die vom Nachlaufbehälter kommende Flüssigkeit mit dem vollen Querschnitt der Rohrleitung,durch die sieflieBt,einwirken kann. Die von oben auf die volle Fläche der Gummiplatte wirkende Kraft entspricht dem Gewicht der Flüssigkeitssäule und ist entsprechend dem Querschnitt der Rohrleitung um ein Vielfaches größer als die von unten durch die Ausgleichsbohrung wirkende Kraft. Dadurch wird die gesamte Flüssigkeit in der hydraulischen Anlage unter einer Vorspannung gehalten, deren Höhe, wie die Praxis ergeben hat, in den meisten Fällen den Ansprüchen genügt.The invention includes all of these multi-part accessories for printing cylinders, especially for hydraulic remote controls, away. According to the invention is only A cover plate over the fine compensating bore, which is controlled by the pressure piston z. B. made of rubber, which is considerably larger in diameter than the cross section the compensating bore and to which the liquid coming from the follow-up container can act with the full cross-section of the pipeline through which it flows. the The force acting on the full surface of the rubber plate from above corresponds to the weight of the liquid column and is around a corresponding to the cross-section of the pipeline Many times greater than the force acting from below through the compensation hole. As a result, the entire fluid in the hydraulic system is under a bias held, the amount of which, as practice has shown, in most cases the claims enough.

Weitere Merkmale der Erfindung sind aus der Beschreibung sowie aus der Zeichnung ersichtlich, in der ein Ausführungsbeispiel veranschaulicht ist. In der Abbildung ist der Druckzylinder mit I, der Druckkolben mit 2 und das zwischen Druckerzeuger I und Nachlaufbehälter 3 liegende Saugventil mit 4 bezeichnet. Ein Rohr 6 verbindet den Nachlaufbehälter 3 mit dem Druckerzeuger I. Über der bekannten Ausgleichsbohrung 8 liegt eine Gummiplatte IO, deren Durchmesser dem Querschnitt der Rohrleitung 6 entspricht und die so angeordnet ist, daß die vom Nachlaufbehälter 3 kommende Flüssigkeit mit dem vollen Querschnitt der Rohrleitung 6 auf die Platte IO einwirken kann.Further features of the invention are evident from the description as well as from the drawing can be seen in which an embodiment is illustrated. In The illustration shows the pressure cylinder with I, the pressure piston with 2 and the one between Pressure generator I and follow-up tank 3, the suction valve is denoted by 4. A Tube 6 connects the follow-up container 3 with the pressure generator I. Above the known Compensating bore 8 is a rubber plate IO, the diameter of which corresponds to the cross section corresponds to the pipeline 6 and which is arranged so that the from the follow-up tank 3 incoming liquid with the full cross section of the pipeline 6 on the plate IO can act.
