Description
Die Erfindung betzifft eine Brennstoffeinspritzpumpe-für Brennkraftmaschinen mit hin, und her gehendem, im, der einen Richtung durch einen Nocken und in der anderen Richtung durch eine Feder bewegten Planger, bei der zwischen: dem Nocken und dem Planger ein aus zwei axial zueinander einstellbaren Teilen bestehendes Führungsstück eingeschaltet ist. Solche Führun:gsistücke sind normalerweise vorgesehen, um den Planger in, die richtige Stellung zu denn Steuerkaraten im Pumpenzylinder oder um die verschiedenem: Planger einer Pumpe mit mehreren Plungern in die richtige Phasenstellung zueinander- zu bringen.The invention relates to a fuel injection pump for internal combustion engines with reciprocating, im, one direction through a cam and in that Planger moved in the other direction by a spring, in which between: the cam and the planger a guide piece consisting of two axially adjustable parts is switched on. Such guides are normally provided around the Planger in, the right position for the control carats in the pump cylinder or around the different: Planger of a pump with several plungers in the correct phase position to bring together.
Die Erfindung sieht eine besondere Ausbi.ldung und Zugänglichkeit des Führungsstückes vor, die eine einfache und schnell durchzuführende Einstellung des Pumpenkolbens ermöglicht. Sie besteht darin., daß, der von der Feder belastete Teil des Führungsstückes das der Feder zugekehrte Ende der Führungshülse übergreift und wenig in die Führungshülse eintaucht und das. Pumpengehäuse eine im Bereich des Zwischenstückes liegende Öffnung zum Einbringen und Auswechseln von Beilagescheiben zwischen den Teilen des Führungsstückes ohne Zerlegung der Pumpe aufweist. Diese Anordnung gestattet es, das von der Feder unter Druck gesetzte Zwischenstück entgegen der Federkraft zum Zwecke des Einbringens, und Auswechselas der Beilagescheiben von der Führungshülse abzuheben und die Beilagescheiben. von der Seite her zwischen die beiden Teile zu bringen.The invention provides for a special training and accessibility of the guide piece, which is a simple and quick adjustment of the pump piston allows. It consists in the fact that the one loaded by the spring Part of the guide piece engages over the end of the guide sleeve facing the spring and dips little into the guide sleeve and the pump housing one in the area opening on the intermediate piece for inserting and replacing washers having between the parts of the guide piece without disassembling the pump. These Arrangement makes it possible to oppose the intermediate piece placed under pressure by the spring the spring force for the purpose of introducing and replacing the washers lift off the guide sleeve and remove the washers. from the side between bring the two parts.
In der Zeichnung i.st eine Brenus.toffeinspritzpumpe gemäß, der Erfindung für Seitenansicht, teilweise aufgeschnitten, dargestellt.In the drawing i.st a Brenus.toffeinjection pump according to the invention for side view, partially cut open, shown.
Mit a ist das Pumpengehäuse, mit b der Pumpenplunger oder einer der Pumpenplunger bezeichnet. Dieser Planger wird in der Richtung nach oben durch den Nocken c und in der entgegengesetzten Richtung durch die Freier e bewegt. Die Bewegung des Nockens c wird auf den Planger b über ein Führungsstück übertragen, das aus zwei Teilen e und f besteht. Der Hauptteil e isst als Hohlzylinder ausgebildet und in der -Bohrung g des Pumpengehäuses gleitbar angeordnet. An seinem unteren, Ende weist es eine Rolle h auf, die mit dem Nocken c zusammenarbeitet. In der Nähe des, anderen Endes ist in dem Teil e eine Eindrehung vorgesehen, in der der andere Teil f des Führungsstückes teleskopartig verschiebbar ist. Dieser Teil ist an seiner Außenseite mit dem Pumpenplunger b verbunden und weist hier eine ringförmige Anlagefläche für die Feder d auf. Zur Einstellung der beiden Teile des Führungsstückes zueinander werden: eine oder mehrere ringförmige Beilagescheiben j zwischen die beiden Teile eingelegt. Sie legen sich dabei auf die Schulter i der Eindrehung des Hauptteiles e auf und bilden eine Anlagefläche für das innere Ende des anderen Teils f.The pump housing is designated with a, the pump plunger or one of the pump plungers with b. This planger is moved in the upward direction by the cam c and in the opposite direction by the suitor e. The movement of the cam c is transmitted to the planger b via a guide piece, which consists of two parts e and f . The main part e is designed as a hollow cylinder and slidably arranged in the bore g of the pump housing. At its lower end, it has a roller h that cooperates with the cam c. In the vicinity of the other end, a recess is provided in part e, in which the other part f of the guide piece is telescopically displaceable. This part is connected on its outside to the pump plunger b and here has an annular contact surface for the spring d. To adjust the two parts of the guide piece to one another: one or more annular washers j are inserted between the two parts. You lay on the shoulder i of the recess of the main part e and form a contact surface for the inner end of the other part f.
Um eine Einstellung der beiden Teile des Führungsstückes nach dem Zusammenbau der Pumpe durchführen zu können, wird der Teil f mittels eines besonderen Werkzeuges, das durch eine Seitenöffnung des Pumpengehäuses eingeführt wird, von dem Hauptteil e entgegen der Kraft der Feder d abgehoben, so daß man dann Beilagescheiben einlegen oder gegen vorhandene austauschen kann. Der Teil f legt sich dann unter der Wirkung der Feder wieder gegen die Beilagescheiben an.To adjust the two parts of the guide piece after To be able to assemble the pump, part f is made using a special Tool that is inserted through a side opening of the pump housing from the main part e lifted against the force of the spring d, so that you then have washers can insert or exchange for existing ones. Part f is then placed under the action of the spring against the washers again.
Man erkennt, da3 das Führungsstück besonders einfach im Aufbau ist und daß die axiale Einstellung der beiden Teile des Führungsstückes. sich besonders leicht und bequem durchführen läßt. .It can be seen that the guide piece is particularly simple in structure and that the axial adjustment of the two parts of the guide piece. especially can be carried out easily and conveniently. .
