Description

Ventillose Pumpe, insbesondere zur Förderung von Schmieröl.. Die Erfindung betrifft eine ventillose Pumpe, insbesondere zur Förderung von Schmieröl, mit in einem Zylinder auf- und abwärts bewegtem Kolben. Das Neue der Erfindung besteht darin, daß das Öl dem Zylinder durch vom Kolben abschließbare Öffnungen unmittelbar unter dem Kolben zufließt und beim Heruntergehen des Kolbens durch eine in seinem Boden befindliche feine. Öffnung in eine Längsbohrung gedrückt wird, von der aus es weiter in einen den Kolben umgebenden Druckraum gefördert wird, wobei die Kolbenbodenöffnung so fein ist, daß das Öl beim Wiederheraufgehen des Kolbens nicht schnell genug durch sie zurücktreten kann, um ein praktisch merkliches Stören des Ölkreislaufes zu bewirken.Valveless pump, especially for pumping lubricating oil .. The invention relates to a valveless pump, especially for pumping lubricating oil, with in a cylinder moving up and down piston. The novelty of the invention consists in that the oil enters the cylinder through openings that can be closed by the piston flows under the piston and when the piston goes down through one in his Fine on the ground. Opening is pressed into a longitudinal bore from which it is further conveyed into a pressure chamber surrounding the piston, the piston crown opening is so fine that the oil does not come through quickly enough when the piston comes back up it can step back in order to cause a practically noticeable disturbance of the oil circuit.

Der Erfindungsgegenstand ist auf der Zeichnung im Längsschnitt dargestellt.The subject of the invention is shown in the drawing in longitudinal section.

In dem Zylinder x bewegt sich der Kolben 2, der von dem Exzenter 3 angetrieben wird. Die Pumpe steht in dem Ölgefäß q., derart, daß das Öl dem unter dem Kolben befindlichen Zylinderraum ohne weiteres durch die Öffnungen 5 zufließen kann. In der. Zeichnung befindet sich der Kolben gerade in seiner höchsten Stellung. Beim Heruntergehen schließt er zuerst die Öffnungen 5 ab und treibt dann das unter ihm befindliche Öl durch die in seinem Boden befindliche feine Öffnung 6 in eine in ihm befindliche acbsiale Bohrung 7, von der aus durch die radialen Öffnungen 8 in den den Kolben umgebenden, im Zylinder befindlichen Druckraum g, von dem es dann weiter zu den Schmierstellen gedrückt wird. Soweit ist das Pumpverfahren im wesentlichen nicht mehr neu. Wenn der Kolben nun wieder hoch geht, sollte man annehmen, daß er sich Öl in den. unter ihm befindlichen Raum nicht nur aus dem Ölgefäß q. ansaugt, sondern auch aus dem über ihm befindlichen Druckraum, so daß eine regelmäßige Ölförderung nicht stattfinden könnte. Dieses ist aber, wie Versuche ergeben haben, nicht der Fall. Wenn die Öffnung 6 genügend klein gewählt wird, ist der Rückflug des Öles durch sie praktisch zu vernachlässigen, so daß die Pumpe praktisch so arbeitet, als ob sie mit richtigen Ventilen versehen wäre und ein fortdauerndes Fördern des Öles ergibt.The piston 2, which is driven by the eccentric 3, moves in the cylinder x. The pump is located in the oil vessel q. In such a way that the oil can easily flow through the openings 5 to the cylinder space located under the piston. In the. Drawing, the piston is currently in its highest position. When going down, it first closes the openings 5 and then drives the oil under it through the fine opening 6 in its bottom into an acbsiale bore 7 in it, from which through the radial openings 8 in the surrounding the piston, in Cylinder located pressure chamber g, from which it is then pushed on to the lubrication points. So far, the pumping process is essentially nothing new. If the piston now goes up again, one should assume that there is oil in the. space below it not only from the oil compartment q. sucks, but also from the pressure chamber located above it, so that regular oil production could not take place. However, as tests have shown, this is not the case. If the opening 6 is chosen to be sufficiently small, the return of the oil through it is practically negligible, so that the pump works practically as if it were provided with correct valves and results in a continuous delivery of the oil.
