Description
Die bisher im Lastwagen zum Betätigen von livdraulisclien Anlagen, wie z. B. hydraulischen Kipper und Hebevorrichtungen, verwendeten Druckpumpen für Flüssigkeiten haben den Nachteil, daß sie einen abschaltbaren Antrieb erfordern, der meist sehr teuer ist. Durch Exzenterwelle an-(,l,etriel)ene Druckpumpen sind bekannt. Sie besitzen entweder Pleuel oder federbelastete Kolben und für jeden Kolben ein Saug- und Druckventil.The previously in the truck to operate livdraulic systems, such as B. hydraulic dump trucks and lifting devices, pressure pumps used for Liquids have the disadvantage that they require a drive that can be switched off. which is usually very expensive. By eccentric shaft on - (, l, etriel) ene pressure pumps are known. They either have connecting rods or spring-loaded pistons and for each piston a suction and pressure valve.
Bei der vorliegenden Erfindung handelt es sich um eine Druckpumpe für Flüssigkeiten, deren Exzenter oder Kurbelwelle ständig mitläuft, also nicht abgeschaltet zu werden braucht. Dadurch vereinfacht sich der Antrieb, und es ist die Möglichkeit Begehen, beim Fehlen eines Nebengetriebes diese Pumpen von irgendeiner geeigneten Stelle des Motors aus anzutreiben.The present invention is a pressure pump for liquids whose eccentric or crankshaft runs constantly, i.e. not needs to be turned off. This simplifies the drive, and it is the possibility of committing these pumps from any one in the absence of a secondary gear appropriate point of the motor to drive.
Die Fig. i bis 3 zeigen drei Ausführungsbeispiele. In dem Gehäuse i i,st die Exzenterwelle 2 gelagert, deren Lager 3 gegen den aus dem Arbeitskoll>en 4 und dem Steuerkolben j bestehenden Stufenkolben drückt, dessen kleiner Steuerkolben 5 in den Druckraum 6 der Pumpe ragt. Das Saugventil 7 und das Druckventil 8 entsprechen der üblichen Bauart bei Pumpen. Herrscht im Druckraum 6 Druck. so wird durch den Steuerkolben 5 der Arbeitskolben 4 gegen den Exzenter gedrückt. Bei dieser Bewegung wird im Raum 9 über Flüssigkeit angesaugt. Durch den Exzenter wird der Arbeitskolben 4 in den Raum 9 gedrückt, wodurch die darin befindliche Flüssigkeit über das Druckventil 8 in den Druckraum 6 gedrückt wird. Herrscht im Raum 6 kein Druck, so kann kein Druck auf den Steuerkolben 5 erfolgen, somit wird auch der Arbeitskolben nicht bewegt, er bleibt in der Ruhelage und die Exzenterwelle läuft leer.FIGS. I to 3 show three exemplary embodiments. In the case i i, the eccentric shaft 2 is mounted, the bearings 3 of which against the one from the working cylinder 4 and the control piston j presses the existing stepped piston, its small control piston 5 protrudes into the pressure chamber 6 of the pump. The suction valve 7 and the pressure valve 8 correspond the usual design for pumps. There is pressure in pressure chamber 6. so becomes through the Control piston 5 of the working piston 4 pressed against the eccentric. With this movement is sucked in via liquid in space 9. The working piston is driven by the eccentric 4 pressed into the space 9, whereby the liquid located therein via the pressure valve 8 is pressed into the pressure chamber 6. If there is no pressure in room 6, none can Pressure is applied to the control piston 5 so that the working piston is not moved either, it remains in the rest position and the eccentric shaft runs empty.
Zum Ingangsetzen der Pumpe ist es also notwendig, im Druckraum 6 Druck zu erzeugen; dies kann beispielsweise durch einen Kolben io erfolgen, der auf die an den Druckraum 6 an-,geschlossene und nach außen völlig abgesperrte Leitung einen Druck ausübt, durch den der Steuerkolben 5 beaufschlagt wird, so daß die Pumpe zu arbeiten beginnt. Der Stufenkolben 4 und 5 kann sowohl in einem Stück sein als auch aus zwei einzelnen Kolben bestehen.To start the pump, it is therefore necessary to have 6 pressure in the pressure chamber to create; this can be done for example by a piston io, which is on the to the pressure chamber 6, a closed and completely shut off line to the outside Exerts pressure through which the control piston 5 is acted upon, so that the pump closes work begins. The stepped piston 4 and 5 can be in one piece as well consist of two individual pistons.
In Fig.2 ist beispielsweise eine Ausführungsform. gezeigt, bei der die Flüssigkeit aus dem Kurbelgehäuse angesaugt wird und (las Saugventil im Arbeitskolben .4 und das Druckventil i i konzentrisch zum Steuerkolben -5 ausgebildet sind.In Figure 2, for example, is an embodiment. shown at the the liquid is sucked out of the crankcase and (read the suction valve in the working piston .4 and the pressure valve i i are designed concentrically to the control piston -5.
In Fig.3 ist eine ähnliche Ausführung gezeigt, bei welcher die Kolben 4 und 5 fest miteinander verbunden sind und eine Feder 8 sowohl das Druckventil i i schließt als auch den .yrheitskolben .4 in der Ruhelage hält.In Figure 3 a similar embodiment is shown in which the piston 4 and 5 are firmly connected to each other and a spring 8 is both the pressure valve i i closes and holds the .yrheitskolben .4 in the rest position.
Mehrere dieser Pumpen können auf einer finit mehreren Exzentern versebenen Welle nebeneinander angeordnet werden oder auch sternförmig bzw. radial um einen oder mehrere 1?xzenter.Several of these pumps can be leveled on a finite number of eccentrics Shaft are arranged next to each other or in a star shape or radially around one or several 1? xzenter.
