Brennstoffpumpe mit dreiteiliger Spindel für das Saugventil.Fuel pump with three-part spindle for the suction valve.

Patentiert im Deutschen Reiche vom 14. Mai 1922 ab.Patented in the German Empire on May 14, 1922.

Es sind Steuerungen für Explosionsmotoren bekannt, bei denen die Verstellung der Ventilspindel unabhängig vom Hubnocken durch einen Keil erfolgt, welcher seinerseits wieder durch den Regler der Maschine beeinflußt wird.There are known controls for explosion engines in which the adjustment of the valve spindle independently of the lifting cam by means of a wedge, which in turn is influenced by the controller of the machine.

Demgegenüber bezieht sich der Erfindungsgegenstand auf eine Brennstoffpumpe mit dreiteiliger Spindel für das Saugventil, welche sich dadurch kennzeichnet, daß der obere die Brennstoffzuleitung und die Ventilspindel aufnehmende Teil der ganzen Länge nachIn contrast, the subject matter of the invention relates to a fuel pump three-part spindle for the suction valve, which is characterized in that the upper the fuel supply line and the valve spindle receiving part along its entire length

für sich im Pumpengehäuse geführt und die Veränderung der anzusaugenden Brennstoffmenge durch Regelung des Spiels zwischen dem einen Teil und den beiden anderen in bekannter Weise aus einer Schraube und MuIter bestehenden Teilen bewirkt wird, die durch den Nocken angehoben und durch das im Mittelteil eingreifende Zahnradgetriebe gegeneinander verstellt werden, ίο Während somit bei den bekannten Einrichtungen die unmittelbare Regelung des Brennstoffs im Zylinder von Verbrennungskraftmaschinen erzielt bzw. die Zuführung des Gasgemisches reguliert wird, handelt es sich beim Erfindungsgegenstand um die Saugregelung. Gegenüber der bekannten dreiteiligen Spindelzuführung für das Saugventil von Brennstoffpumpen wird durch den Erfindungsgegenstand erreicht, daß das Pumpensaugventil eine empfindlichere, von Drehbewegungen freibleibende Regulierung erfährt.out of itself in the pump housing and the change in the amount of fuel to be sucked in by regulating the play between one part and the other two in a known manner from a screw and The existing parts are raised by the cam and by the gear drives engaging in the middle part are adjusted against each other, ίο While thus with the known devices the direct regulation of the fuel achieved in the cylinder of internal combustion engines or the supply of the gas mixture is regulated, the subject of the invention is the suction control. Compared to the well-known three-part spindle feed for the suction valve of fuel pumps is achieved by the subject matter of the invention that the pump suction valve is subject to a more sensitive regulation that is free of rotary movements.

In den Pumpenkörper 1 ist ein an sich bekannter Brennstoffreiniger 2 eingebaut, welchen der durch eine Öffnung 3 zugeführte Brennstoff durchströmen muß, bevor er durch den Kanal 4 zum Saugventil 5 gelangt. Durch das so erreichte Wegfallen besonderer von außen zugänglicher Leitungen zwischen Reiniger und Pumpe ist sowohl eine Störung durch in die Pumpe gelangende Fremdkörper als auch durch Verringerung des Leitungsquerschnittes, z. B. beim unachtsamen Verdrucken der Rohrleitung, ausgeschlossen. Zur Ermöglichung des Auswaschens der den Reiniger 2 bildenden Siebe ist hinter letzteren eine verschließbare Öffnung 6 im Pumpenkörper 1 vorgesehen, durch welche eine Reinigungsflüssigkeit, z. B. Benzin, eingeschüttet werden kann, welche durch eine unten vorgesehene Öffnung 7 unter Mitnahme der in den Sieben befindlichen Fremdkörper abfließen kann.In the pump body 1, a known fuel cleaner 2 is installed, which the fuel supplied through an opening 3 must flow through before it the channel 4 reaches the suction valve 5. Due to the elimination of special from Externally accessible lines between the cleaner and the pump are both a malfunction by foreign bodies getting into the pump as well as by reducing the line cross-section, z. B. when carelessly printing the pipeline, excluded. To enable the screens forming the cleaner 2 to be washed out, there is a closable opening 6 in the rear of the latter Pump body 1 is provided through which a cleaning liquid, e.g. B. Gasoline, poured can be, which through an opening 7 provided below, taking along the foreign bodies located in the sieves can drain.

Der Antrieb des Saugventils 5 und der Pumpe 8 erfolgt in bekannter Weise mittels Nocken 9, 10, die auf der Antriebswelle 11 befestigt sind. Zur Ermöglichung der Regelung der angesaugten Brennstoffmenge ist der Ventilkörper 12 des Saugventils mit dem vom Antriebsnocken 9 beeinflußten, in einem Vierkant geführten Druckstück 13 nicht starr verbunden, sondern so, daß die Größe des Hubes des Ventils 12 verändert werden kann. Dies wird nach der Erfindung in der Weise ermöglicht, daß das Druckstück 13 gegenüber der Ventilspindel 12 etwas Spiel hat, dessen Größe von außen geregelt werden, kann. Das Druckstück 13 wird also je nach Einstellung der Größe des Spiels früher oder später gegen das untere Ende der Ventilspindel 12 stoßen und letztere anheben.The suction valve 5 and the pump 8 are driven in a known manner by means of Cams 9, 10, which are on the drive shaft 11 are attached. To enable the amount of fuel drawn in to be regulated, the Valve body 12 of the suction valve with the from Drive cam 9 influenced, in a square guided pressure piece 13 not rigidly connected, but so that the size of the stroke of the valve 12 can be changed. this is made possible according to the invention in such a way that the pressure piece 13 opposite the valve spindle 12 has some play, the size of which can be regulated from the outside. That Pressure piece 13 is so depending on the setting of the size of the game against sooner or later push the lower end of the valve stem 12 and raise the latter.

Die Einstellung des auf der Zeichnung mit s bezeichneten Spiels zwischen dem Druckstück 13 und der Ventilspindel 12 erfolgt beim dargestellten Ausführungsbeispiel dadurch, daß das aus zwei gegeneinander verschraubbaren Teilen Γ3, 13° bestehende Druckstück mittels eines durch Kurbel 14 und Welle 15 von außen drehbaren Zahnrades i6, das in ein auf dem Druckstückteil 13s befestigtes Ritzel 17 eingreift, verlängert oder verkürzt wird. Bei Mehrzylinderanordnung können mit dem Einstellzahnrad 16 auch die Ritzel 17 der Einstellvorrichtungen mehrerer Pumpen in Eingriff stehen.The setting of the play, marked s in the drawing, between the pressure piece 13 and the valve spindle 12 takes place in the illustrated embodiment in that the pressure piece consisting of two mutually screwable parts Γ3, 13 ° by means of a crank 14 and shaft 15 rotatable from the outside gear i6 , which engages in a pinion 17 attached to the pressure piece part 13 s , is lengthened or shortened. In the case of a multi-cylinder arrangement, the pinions 17 of the setting devices of several pumps can also be in engagement with the setting gear 16.

Zum Sammeln des zwischen den bewegten Teilen der Pumpe allmählich durchdringenden Brennstoffes ist unten in dem die Antriebswelle 11 und die Nocken 9, ι ο aufnehmenden Hohlraum 18 des Pumpenkörpers eine Sammelrinne 19 vorgesehen, welche an ein Rohr angeschlossen ist, das mit der durch den Kanal 3 eingeführten Brennstoffleitung verbunden werden kann.To collect the gradually penetrating between the moving parts of the pump Fuel is down in which the drive shaft 11 and the cams 9, ι ο receiving Cavity 18 of the pump body a collecting channel 19 is provided which is connected to a pipe which is connected to the fuel line introduced through the channel 3 can be connected.
