Description

Die Erfindung bezieht sich auf Kraftstoffpumpen für%Brenitkraftmaschinen und betrifft den Antrieb derartiger Pumpen.The invention relates to fuel pumps for fuel engines and relates to the drive of such pumps.

Es dst bekannt, Kraftstoffpumpen mechanisch von einer Hilfsnockenwelle der Brennkraftmaschine anzutreiben. Diese Antriebsart hat den Nachteil, daß die Pumpen beim Anlassen der Brennkraftmaschine nur mit geringer Hubzahl angetrieben werden, so daß die Förderung der Pumpen unzureichend ist.It is known to pump fuel mechanically from an auxiliary camshaft to drive the internal combustion engine. This type of drive has the disadvantage that the Pumps are only driven with a low number of strokes when the internal combustion engine is started so that the delivery of the pumps is insufficient.

Man hat aus diesem Grunde die Kraftstoffpumpen elektrisch angetrieben, und zwar mit Hilfe einer Magnetspule mit Tauchkolben, wobei der Spulenstrom durch vom tauchkolben betätigte Kontakte gesteuert wird. Der elektrisch° Antrieb der Kraftstoffpumpen hat den Nachteil, daß der Strom für die Erregung der Magnetspule der Batterie entnommen und eiese daher häufiger als sonst geladen werden muß, was unerwünscht ist und zudem die Lebensdauer der Batterie herabsetzt. Für die Verwendung einer größeren Batterie ist jedoch, insbesondere .bei Fahrzeugen, häufig der erforderliche kaum nicht vorhanden.For this reason the fuel pumps were driven electrically, with the help of a solenoid with a plunger, the coil current through contacts operated by the plunger are controlled. The electric drive of the fuel pumps has the disadvantage that the current for exciting the magnetic coil is drawn from the battery and it therefore has to be charged more frequently than usual, which is undesirable and also reduces the service life of the battery. For using a larger battery however, especially in the case of vehicles, the required information is often hardly available.

Die Nachteile beider Antriebsarten lassen sich vermeiden, wenn die Pumpe erfindungsgemäß sowohl mit mechanischen wie mit elektrischen Antriebsmitteln ausgerüstet ist. In diesem Falle kann die Pumpe bei nicht ausreichender Drehzahl des mechanischen Antriebes, also insbesondere beim Anlassen des Motors, elektrisch und bei ausreichender Drehzahl des Motors mechanisch angetrieben werden.The disadvantages of both types of drive can be avoided if the Pump according to the invention with both mechanical and electrical drive means is equipped. In this case, the pump can run at insufficient speed of the mechanical drive, especially when starting the engine, electrically and driven mechanically when the engine speed is sufficient.

Gegebenenfalls kann der Schalter für den elektrischen Antrieb mit dem Anlaßschalter für den Anwurfsmotor der Brennkraftmasch.ine verbunden und so die Dauer des elektrischen Antriebes auf die Anlaßzeit der Brennkraftmaschine begrenzt sein.If necessary, the switch for the electric drive can also be used connected to the starter switch for the starter motor of the internal combustion engine and so on the duration of the electric drive is limited to the starting time of the internal combustion engine be.

Die Erfindung und weitere Merkmale der Erfindung sind im folgenden an Hand der Zeichnung beschrieben, in .dieser zeigt Abb. t eine Membrankraftstoffpu.mpe mit elektrischem und mechanischem Antrieb gemäß der Erfindung zu Beginn und :\bh. 2 die gleiche Pumpe am Ende des Saughubes.The invention and other features of the invention are as follows described on the basis of the drawing, in this Fig. t shows a membrane fuel pump.mpe with electrical and mechanical drive according to the invention at the beginning and: \ bh. 2 the same pump at the end of the suction stroke.

In der Zeichnung ist das Gehäuse der Membrankraftstoffpumpe m.it t, die -Membran selbst ist mit :2 bezeichnet. Die l@@fembr.an ist durch eine Feder 3 belastet, die sie in der in Abb. i gezeigten Lage zu halten sucht. An der Membran ist der Tauch- kolben d einer 'Magnetspule 3 befestigt. Die SI>ule 5 ist an eine Batterie 6 angeschlossen, wobei im Stromkreis der Spule z\cei Schalter 7 und 8 an- geordnet sind. Der Schalter 7 wird von Hand betätigt und dient zuin I?iti- und Abschalten d.es elektrischen Antriebes, der Schaltei-8 wird durch einen Flansch 9 am Tauchkolben d gesteuert, er ist zu Beginn des Sau #rhuhes geschlossen und an seinem Ende. wie in =\lili.2 gezeigt. geöffnet. Beim Saughub wird der Tauchkolben 4 entgegen der Feder 3 in die SI>nle 5 hilieingezogen, der Druckliul> wird durch die l@ eder 3 ausgeführt. Für den mechanischen _\titriel> der N-lembran 2 ist ain Tauchkolben 4 ein \litnehmer io an- gebracht. In diesen \littiehiner greift ein Winkel- hebel t i ein. mit ihm gleichachsig gelagert ist ein Hebel 12.> der durch eine Feder 13 gegeit den Nocken 14 einer Hilfswelle 1,3 gedrückt wird. 1)er Hebel 12 drückt mit einer Nase 13 gegen d211 Hebelarm 17 des Hebels 1 1. @@-ctin der Hebel 12 durch .den.

Der Hebel t t kann sich aber unabhängig vom Hebel 12 im Uhrzeigersinn drehen, wie dies die Abb. 2 zeigt, der 11elr2l t i ist also mit -deni Hebel i2 lediglich kraftschlüssig verbunden. Der elektrische Antrieb der Pumpe kann also unab- hängig vorn mechanischen _\ittrielt xirksain werden, und zwar so lange. wie der Schalter ; eingelegt ist, l;°,ispielsweise für die Datier des _\nlassens der Brennkraftmaschinc. l:s wird also der 13attel-i° durch den elektrischen .\ntrieli der Pumpe nur kurzzeitig Strom entnommen, so daß dieser Strom- verbrauch für die Entladung der I ,sttterie nicht ins Gewicht fällt. In the drawing, the housing of the diaphragm fuel pump is m.it t, the diaphragm itself is denoted by: 2. The l @@ fembr.an is loaded by a spring 3, which it closes in the position shown in Fig. I keep looking. On the membrane is the immersion piston d a 'solenoid 3 attached.
