Description

Druck-Hubzylinder mit Energiespeicherung Es sind eine Vielzahl von Druck- und Hubzylindern bekannt, bei denen Uber einen Kolben mit Kolbenstange die eingeleitete Druckenergie durch Verschieben des Kolbensystems Uber Federn, also .mechanisch oder Uber pneumatische oder hydraulische Medien, im letzteren Fall vorzugsweise durch eine Servowirkung, gespeichert und rtlckfUhrbar wird. Energy storage pressure lift cylinder There are a variety of Known pressure and lifting cylinders in which the pressure energy introduced by moving the piston system via springs, that is Mechanically or via pneumatic or hydraulic media, preferably in the latter case by a servo effect, is stored and can be returned.

Dts im folgenden beschriebene Verfahren geht von dem Relativprinzip der Energiespeicherung aus, wie es von Pascal im Jahre 1650 gefunden wurde.The method described in the following is based on the relative principle energy storage, as found by Pascal in 1650.

Dieses Prinzip wird im folgenden in einer Anordnung beschrieben, die es ermöglicht, Bewegungsenergie zu speichern und diese Energie umgekehrt wieder dem System als Bewegungsenergie zuzufUhren.This principle is described below in an arrangement that it enables kinetic energy to be stored and this energy reversed again to feed the system as kinetic energy.

Eine diesem Verfahren zugrunde liegende AusfUhrungsform besteht aus einem Speicherzylinder (1), welcher in seinem ölgefUllten Teil durch den beweglichen Kolben (2) abgeschlossen wird. Der Kolben (2) wird durch die Speicherfeder (3) entsprechend der Tauchlage des Kolbens (4) in seiner Lage entsprechend den Querschnittverhältnissen des Kolbens (2) zum Kolben (4) bewegt. Dabei wird ebenfalls im Verhältnis der beiden Kolbenquersohnitte eine Druckerhöhung (Energiespeicherung) eintreten, welche nach Aufhören der Belastung des Kolbens (4) rrei wird und, wenn keine Blockierung vorgesehen ist, den Kolben (4) wieder in seine Ausgangslage zurUakwahrt.An embodiment on which this method is based consists of a storage cylinder (1), which in its oil-filled part by the movable Piston (2) is closed. The piston (2) is activated accordingly by the accumulator spring (3) the immersion position of the piston (4) in its position according to the cross-sectional ratios of the piston (2) moves towards the piston (4). It is also in the ratio of the two Piston crosswise a pressure increase (energy storage) occur, which after The load on the piston (4) stops and if no blockage is provided is to return the piston (4) to its original position.

Die Umkehrung des oben beschriebenen Verfahrens kann dazu verwendet werden, Kraftverstärker, insbesondere Bremsdruckverstärker, in einfacher Weise aufzubauen. Auf der Zeichnung Nr. 0002 ist ein derartiges Druckverstkrkersystem im Prinzip dargestellt.The reverse of the procedure described above can be used are to build power boosters, in particular brake pressure boosters, in a simple manner. Such a pressure amplifier system is shown in principle on drawing No. 0002.

Im ölgeftillten Speicherzylinder (1) ist der Verstärkerkolben (2) beweglich eingebaut und schließt den darUber liegenden blraum ab.The booster piston (2) is in the oil-filled storage cylinder (1) movably built in and closes off the bloom above.

Wird auf den Steuerkolben (3) ein Druck ausgeUbt, so bewegt sich der Kolben in das untere Ölvolumen des Speicherzylinders; der dabei auftretende Druckanstleg wird ueber den Kolben (2) auf den geschlossenen Druckkreis, der an den oberen Teil des Verstärkerzylinders angeschlossen ist, Ubertragen. Die Dimensionierung kann so vorgenommen werden, daß bereits relativ kleine Bewegungen des Steuerkolbens (3) zu entsprechenden Kräften im Druclckreis eines Systems fUhren.If pressure is exerted on the control piston (3), it moves Piston in the lower oil volume of the storage cylinder; the resulting pressure increase is via the piston (2) on the closed pressure circuit that is attached to the upper part of the booster cylinder is connected, transmit. The dimensioning can be made so that even relatively small movements of the control piston (3) lead to corresponding forces in the pressure circle of a system.

Wird an den geschlossenen Druckkreis ein druckelastischer Kreis angeschlossen, dann kann im Raum A" ein vom elastischen Druckkreis abhängiger variabler Gegendruck erzeugt werden, der ein vollhydraulisches schwingendes Energiespeicher ergibt.If a pressure-elastic circuit is connected to the closed pressure circuit, then a variable counter-pressure dependent on the elastic pressure circuit can occur in space A ″ be generated, which results in a fully hydraulic oscillating energy store.
