Description
Hydraulisches Gerät, Pumpe oder Motor Es ist bekannt, bei hydraulischen Motoren oder Pumpen durch Phasenverschiebung der Kolben von miteinander korrespondierenden Kolbenzylindern die Fördermenge bzw. Leistungsabgabe zu regeln. Diese Regelung erfordert einen nicht unerheblichen technischen Aufwand, z. B. die Anwendung von Differentialgetrieben, die Verschiebung von Nockenwellen u. dgl., technische Elemente, die an sich der Hydraulik fremd sind.Hydraulic device, pump or motor It is known in hydraulic Motors or pumps by phase shifting the pistons of mutually corresponding Piston cylinders to regulate the delivery rate or power output. This regulation requires a not inconsiderable technical effort, e.g. B. the use of differential gears, the displacement of camshafts and the like, technical elements that are inherent in the Are foreign to hydraulics.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, die Leistungsregelung von Pumpen oder Motoren unter Verwendung von in der Hydraulik üblichen Elementen oder Geräten vorzunehmen.The present invention is based on the task of regulating the power of pumps or motors using elements common in hydraulics or devices.
Die Lösung der Aufgabe besteht darin, daß durch ein an sich bekanntes Steuergerät jeder Zylinder mit jedem anderen Zylinder zu einem Paar verbunden werden oder auch für sich allein arbeiten kann.The solution to the problem is that by a known per se Control unit each cylinder can be paired with each other cylinder or can work alone.
Das Gesamtgerät besteht beispielsweise aus sechs Kolbenzylindern A, B, C und 1, 2; 3 und einer Regelvorrichtung 4, in die der Zufluß 5 einmündet und die es gestattet, die Verbindungsleitungen 6, 7, 8, 9, 10 und 11. zwischen Regelorgan und den Zyhndern gegenseitig anzuschließen, derart, daß beliebig gewählte Zylinder in gegenseitiger hydraulischer Verbindung stehen.The entire device consists, for example, of six piston cylinders A, B, C and 1, 2; 3 and a control device 4, into which the inflow 5 opens and which allows the connecting lines 6, 7, 8, 9, 10 and 11 to be mutually connected between the control element and the cylinders, such that any cylinders selected are in mutual hydraulic connection .
Bei jedem der zwei Zylindersätze A, B, C einerseits und 1 bis 3 andererseits sind die Kolben gegeneinander um 120° phasenverschoben. Die Kurbelwellen der beiden Zylindersätze A, B, C und 1 bis 3 sind dann in der Weise miteinander gekoppelt, daß der Kolben des Zylinders 1 dem Kolben des Zylinders A um 60°, der Kolben des Zylinder 2 dem Kolben B um 60° und der Kolben des Zylinders 3 dem Kolben C ebenfalls um 60° nacheilt. Diese Phasenverschiebung ist also eine konstante, urveränderbare. Zur Regelung der Leistung der Pumpe oder des Motors wird nicht die gegenseitige Verschiebung der Phase der Kolben verändert, sondern es werden wechselweise verschiedene Zylinder miteinander hydraulisch verbunden, um durch die Druckleitung 5 gespeist zu werden.In each of the two cylinder sets A, B, C on the one hand and 1 to 3 on the other hand, the pistons are phase-shifted by 120 ° with respect to one another. The crankshafts of the two cylinder sets A, B, C and 1 to 3 are then coupled with one another in such a way that the piston of cylinder 1 corresponds to the piston of cylinder A by 60 °, the piston of cylinder 2 to piston B by 60 ° and the Piston of cylinder 3 also lags piston C by 60 °. This phase shift is therefore a constant, unchangeable one. To regulate the power of the pump or the motor, the mutual shifting of the phase of the pistons is not changed, but different cylinders are alternately hydraulically connected to one another in order to be fed through the pressure line 5.
Bei Verbindung von A: mit 2 ist der Lieferungsgrad bzw. die Leistungsabgabe dieser beiden Zylinder gleich Null, da sie um 1$0° gegeneinander versetzt sind. Dasselbe gilt für C 1 und B 3.When connecting A: with 2 is the degree of delivery or the power output of these two cylinders are equal to zero because they are offset from one another by 1 $ 0 °. The same is true for C 1 and B 3.
Die Verbindung A mit 1 bewirkt einen Lieferungsgrad von 1,33; ebenso die Verbindung B 2 und C 3, da die Kolben dieser beiden Zylinder nur um 60° gegeneinander phasenverschoben sind.The compound A with 1 causes a degree of delivery of 1.33; as well the connection B 2 and C 3, since the pistons of these two cylinders are only 60 ° against each other are out of phase.
Die Verbindung A mit B, B mit C oder C mit A bewirkt einen Lieferungsgrad von 0,67; ebenso von 1 mit 2, 2 mit 3 und 3 mit 1. Demgemäß bewirkt die Verbindung A mit B mit C und 1 mit 2 mit 3 den Lieferungsgrad bzw. die Leistungsabgabe Null.The connection A with B, B with C or C with A causes a degree of delivery of 0.67; likewise from 1 with 2, 2 with 3 and 3 with 1. Accordingly, the connection A with B with C and 1 with 2 with 3 results in the degree of delivery or the power output zero.
Es bewirkt die Verbindung A mit 2, B mit C und 1 mit 3 den Lieferungsgrad und die Leistungsabgabe 1,33;A mit B, 1 mit 2 mit 3, C allein: 1,67, und natürlich kann auch jede andere Kombination dieser Art gewählt werden.The connection A with 2, B with C and 1 with 3 causes the degree of delivery and the power output 1.33; A with B, 1 with 2 with 3, C alone: 1.67, and of course any other combination of this type can also be selected.
Dabei ergeben sich beispielsweise folgende Möglichkeiten (es ist vorausgesetzt,
daß die Zylinder gleich sind und daß der Lieferungsgrad eines Zylinders bei vollem
Hub gleich Eins gesetzt ist):
