Description

Bei vorliegender Erfindung handelt es sich um eine Zahn- oder Flügelradpumpe, bei der der von der Pumpe erzeugte Druck mittels eines doppelwirkenden Stufenkolbens im Verhältnis der Flächenunterschiede auf Hochdruck übersetzt wird. Es ist an und für sich das Übliche, Hochdrücke mit Hilfe von Stufenkolben zu erzeugen.The present invention is a gear or impeller pump, where the pressure generated by the pump by means of a double-acting stepped piston is translated to high pressure in the ratio of the area differences. It is on and the usual thing in itself to generate high pressures with the help of stepped pistons.

Bei den bekannten Hochdruckpumparten handelt es sich oft um Kopplungen von mehreren Kolben bzw. Kreisel- mit Kolbenpumpen oder rotierende Kolbenpumpen, die in ihrer Bauart kompliziert und teuer sind, da sie meistens hohe Leistungen oder besondere Steuerorgane benötigen.The known types of high pressure pumps are often couplings of several pistons or centrifugal with piston pumps or rotating piston pumps, which are complex and expensive in their design, since they are mostly high performance or require special control organs.

Bei vorstehender Pumpe sind zusätzliche Leistungen oder Umsteuerungen vermieden.With the above pump there are additional services or reversals avoided.

Die Steuerung erfolgt jeweils durch das angetriebene Zahnrad. Dadurch wird -die Pumpe in ihrer Bauweise einfach und sehr billig. Außerdem verfährt der Stufenkolben keinen Leerhub, sondern durch die doppelte Wirkung ist jeder Hub ein Arbeitshub.The control takes place in each case by the driven gear. Through this -the pump is simple and very cheap in its construction. In addition, the Stepped piston does not have an idle stroke, but rather each stroke is one due to the double effect Working stroke.

Die Wirkungsweise der Pumpe ist wie folgt: Das angetriebene Zahnrad besitzt auf halbem Umfang die um i8o° zueinander versetzten Nuten a und a1. Die stehende Zahnradwelle ist als Zylinder ausgebildet und besitzt die beiden Nuten c und d. Die Nut c ist durch den Kanal e mit der Saugseite und die Nut d ist durch den Kanal f mit der Druckseite verbunden.The operation of the pump is as follows: The driven gear wheel has grooves a and a1 offset from one another by 180 ° on half its circumference. The stationary gear shaft is designed as a cylinder and has the two grooves c and d. The groove c is connected to the suction side through the channel e and the groove d is connected to the pressure side through the channel f.

Neben den Nuten befinden sich auf dem Umfang die Zylindereintritte bzw. Austrittsöffnungen g1, g2, g3 und g4. Während des Laufens tritt das Öl von der Druckseite über den Kanal f in die Nut d. Die Nut d wird von der Nut a1 des Zahnrades während einer halben Umdrehung überdeckt. Während dieser Zeit strömt das 01 durch die Bohrung g'= in den Zylinder und gleichzeitig über das Rückschlagventil li in den Raum i hinter den kleinen Kolben. Der Kolben k wird nun nach links geschoben. Das vor dem Kolben k befindliche 01 kann durch die Bohrung g4 über die Nut a des Zahnrades in die Nut c und durch den Verbindungskanal e in die Saugseite austreten. Dabei wird das 01, welches im Raum l hinter dem kleinen Kolben steht, über das Rückschlagventil m in die Hochdruckleitung geschoben. Während der nächsten halben Umdrehung überdeckt die Nut a des Zahnrades die Nut d des Zylinders. Da aber die Nut d immer mit der Druckseite in Verbindung steht, tritt nun das Öl durch die Bohxung g1 hinter den Kolben k und schiebt denselben nach rechts, gleichzeitig tritt das Öl über das Rückschlagventil hl in den Raum L und füllt diesen Raum. Das vor dem Kolben k befindliche Ö1 kann durch die Bohrung g,3 über die Nut a1 in die Nut c und den Verbindungskanal e in die Saugseite austreten. Das im Raum i befindliche Öl wird über das Rückschlagventit ml in die Hochdruckleitung geschoben.In addition to the grooves, the cylinder inlets or outlet openings g1, g2, g3 and g4 are located on the circumference. While running, the oil comes from the pressure side via the channel f into the groove d. The groove d is covered by the groove a1 of the gear for half a revolution. During this time the 01 flows through the bore g '= into the cylinder and at the same time via the check valve li into the space i behind the small piston. The piston k is now pushed to the left. The k located before the piston 01 through the bore c can g4 via the groove of the gear a in the groove and exit through the connecting channel e into the suction side. The 01, which is in space l behind the small piston, is pushed into the high-pressure line via the non-return valve m. During the next half revolution, the groove a of the gear wheel covers the groove d of the cylinder. But since the groove d is always connected to the pressure side, the oil now passes through the bore g1 behind the piston k and pushes it to the right, at the same time the oil enters the space L via the check valve hl and fills this space. The oil located in front of the piston k can exit through the bore g, 3 via the groove a1 into the groove c and the connecting channel e into the suction side. The oil in space i is pushed into the high pressure line via the non-return valve ml.
