Description

Es sind Pumpen und Kompressoren mit zwei Kolben bekannt, deren Stellung in bezug aufeinander verändert und auf diese Weise die Leistung· geregelt werden kann. Zur Verbindung der von dem gleichen Antrieb bewegten Kolben hat man hierbei ein Ausgleichsgetriebe, z. B. ein Differential o. dgl., vorgesehen, das die gegenseitige Verstellung der Kolben ermöglicht.There are pumps and compressors with two pistons known, their position in relation changed in relation to each other and in this way the performance · can be regulated. To connect the piston moved by the same drive has a differential gear, z. B. a differential o. The like. Provided that enables the mutual displacement of the pistons.

Die vorliegende Erfindung hat sich nun die Aufgabe gestellt, bei derartigen Pumpen eine selbsttätige Regelung herbeizuführen. Dies geschieht nach der Erfindung dadurch, daß die Ausgleichs- oder Verstellvorrichtung mit einer auf Änderung- der Fördermenge ansprechenden, in der Saugleitung angeordneten Regelvorrichtung zum Verstellen der Ausgleichsvorrichtung und zum Messen der gegenseitigen Phasenlage der beiden Kolben verbunden ist. Durch die Einrichtung kann die Phasenlage der beiden Kolben während des Betriebes geändert und damit die Fördermenge in den gewünschten Grenzen gehalten =werden. In der Figur ist ein Ausführungsbeispiel für die Erfindung dargestellt.The present invention has now set itself the task of bringing about automatic control in such pumps. This is done according to the invention in that the compensating or adjusting device is connected to a regulating device which responds to changes in the delivery rate and is arranged in the suction line for adjusting the compensating device and for measuring the mutual phase position of the two pistons. By setting up the phase position of the two pistons can be changed during operation and are thus kept = the flow rate within the desired limits. In the figure, an embodiment of the invention is shown.

Der Antriebsmotor 15 ist zwischen den beiden Kolben 3 und 4 angeordnet. Der Motor ist mit einem Ritzel versehen, das mit den Rädern 16 und 17 in Eingriff steht. Das Rad 16 ist auf der Kurbelwelle 5 befestigt; das Rad 17 treibt das Glied 18 eines Ausgleichsgetriebes 19 an, dessen zweites Glied mit der Kurbelwelle 6 verbunden ist. Das dritte Glied 21 des Ausgleichsgetriebes 19 ist mit einer Meßvorrichtung 22 verbunden, die bei sich ändernder Fördermenge das Gehäuse so verstellt, daß die Fördermenge wieder auf den gewünschten Wert eingestellt wird.The drive motor 15 is arranged between the two pistons 3 and 4. The motor is provided with a pinion which meshes with the wheels 16 and 17. That Wheel 16 is mounted on the crankshaft 5; the wheel 17 drives the link 18 of a differential gear 19, the second link of which is connected to the crankshaft 6. That third link 21 of the differential gear 19 is connected to a measuring device 22 which if the delivery rate changes, the housing is adjusted so that the delivery rate is restored is set to the desired value.
