Description

Zylinderkopf für eine vorzugsweise mehrzylindrige BrennkraftmaschineCylinder head for a preferably multi-cylinder internal combustion engine

Die Erfindung betrifft einen Zylinderkopf für eine vorzugsweise mehrzylindrige Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a cylinder head for a preferably multi-cylinder internal combustion engine according to the preamble of claim 1.

Bei einem bekannten Zylinderkopf (DE-OS 29 52 290) der genannten Gattung dient zur Druckölversorgung und Schmierung eines Ventilstößels eine Bohrung, die schräg zu einer horizontalen Ebene verläuft und an eine Versorgungsleitung angeschlossen ist. Dieser Ausführung haftet der Nachteil an, daß die Einhaltung von dort üblichen, relativ engen Fertigungstoleranzen schwierig ist, weil diese S.chrägbohrung zum Verlaufen neigt und auch eine relativ große ellyptische Öffnung erzeugt. Zwar besteht die Möglichkeit, an der Innenseite der Stößelbohrung einen Anguß mit einer - zur Winkellage der Bohrung - rechtwinkeligen Anlauffläche vorzusehen, doch würde dies einen zusätzlichen Material- und Bearbeitungsaufwand verursachen.In a known cylinder head (DE-OS 29 52 290) of the type mentioned is used for pressure oil supply and lubrication a valve tappet has a bore which runs obliquely to a horizontal plane and is connected to a supply line is. This version has the disadvantage that it is difficult to comply with the relatively narrow manufacturing tolerances that are customary there, because this inclined bore to the Tends to run and also creates a relatively large elliptical opening. It is possible to participate in the Provide a sprue on the inside of the tappet bore with a contact surface at right angles to the angular position of the bore, but this would cause additional material and processing costs.

Aufgabe der Erfindung ist es, einen Zylinderkopf zu schaffen, dessen für die Schmierung und Drucköl von sich bewegenden Teilen dienende Bohrungen und/oder Kanäle einfach herstellbar sind und eine gute Funktion gewährleisten.The object of the invention is to create a cylinder head, which is used for the lubrication and pressure oil of moving Bores and / or channels serving for parts can be easily produced and ensure good function.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten .According to the invention, this object is achieved by the characterizing Features of claim 1 solved. Further features defining the invention are contained in the subclaims .

Dio mit der Erfindung hauptsächlich erzielten Vorteile sind, darin zu sehen, daß die? Ringnuten, die Versorgungsbohrungen und die Schmierbohrungen fertigungstechnisch - keine Schrägbohrungen - einfach herstellbar sind und eine gute Schmierung bzwL Ölversorgung für die sich bewegenden Teile im Zylinderkopf sicherstellen. Durch die Ringnuten wird zusätzlich erreicht, daß gleichmäßig Spaltöl an der Oberseite der Ventilstößelbohrung, d.h. benachbart der Nockenwelle, austritt, so daß die Nockenlaufflächen der Nockenwelle ohne eine spezielle Einrichtung geschmiert wird. Weisen die Ventilstößelbohrungen und die Schmier-bohrungen eine gemeinsame Bearbeitungsrichtung auf, so entfallen zusätzliche Bohrstationen für die zuletzt genannten.The main advantages achieved with the invention are, to see that the? Ring grooves, the supply holes and the lubrication holes in terms of production technology - no inclined holes - are easy to manufacture and have a good lubrication or oil supply for the moving parts in the cylinder head to ensure. The ring grooves also ensure that evenly gap oil on the top of the valve stem bore, i.e., adjacent to the camshaft, so that the cam surfaces of the camshaft can be accessed without special means is lubricated. If the valve tappet bores and the lubrication bores have a common machining direction, this eliminates the need for additional drilling stations for the latter.
