Description
Gekühltes Brennstoffventil für Dieselmaschinen Die Erfindung betrifft ein gekühltes Brennstoffventil für Dieselmaschinen, bei dem der Ventilkörper vom Zylinderdeckel umgebenist.Cooled Fuel Valve for Diesel Engines The invention relates to a cooled fuel valve for diesel engines, in which the valve body from Cylinder cover is surrounded.
Es ist bekannt, bei derartigen Brennstoffventilen den Kühlraum in der Nähe der Einspritzdüse in dem mit der Düse verschraubten Düsenhalter anzuordnen. Ferner ist es bekannt, die Wände eines Düsenkühlraumes durch miteinander verschweißte Teile herzustellen.It is known, in such fuel valves, the cooling space in near the injection nozzle in the nozzle holder screwed to the nozzle. It is also known to weld the walls of a nozzle cooling chamber together To manufacture parts.
Die Erfindung bezweckt, die Schweißnähte eines auf solche Weise hergestellten Kühlraumes gegen die unmittelbare Einwirkung der hohen Temperaturen des Verbrennungsraumes zu schützen. Sie besteht darin, daß der in der Nähe der Brennstoffdüse vorgesehene Kühlraum von der Mantelfläche des Ventilgehäuses aus nach der Mitte zu durch Drehen oder Fräsen in das Ventilgehäuse eingearbeitet ist, so daß die dem Verbrennungsraum zugekehrte Stirnwand aus dem Vollen herausgearbeitet ist und die Schweißnähte des mehrteiligen hohlzylindrischen, xriit der Gehäuse-wand verschweißten Ringdeckels, durch den der Kühlraum an seinem Umfang abgeschlossen ist, gegen die hohen Temperaturen des Verbrennungsraumes geschützt innerhalb des Zylinderdeckels liegen.The invention aims at the welds of a manufactured in such a way Cooling room against the direct effect of the high temperatures of the combustion chamber to protect. It consists in the one provided near the fuel nozzle Cooling space from the jacket surface of the valve housing towards the middle by turning or milling is incorporated into the valve housing so that the combustion chamber facing end wall is worked out from the solid and the welds of the multi-part hollow cylindrical ring cover welded to the housing wall, by which the cooling space is closed at its periphery, against the high temperatures of the combustion chamber are protected inside the cylinder cover.
In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt. Abb. i zeigt einen Längsschnitt durch das Ventil, Abb. a einen Querschnitt nach der Linie 2-z und Abb. 3 einen Querschnitt nach der Linie 3-3 der Abb. i.In the drawing, the subject matter of the invention is shown for example. Fig. I shows a longitudinal section through the valve, Fig. A shows a cross section the line 2-z and Fig. 3 shows a cross section along the line 3-3 of Fig. i.
Die Einspritzdüse a ist in das Ventilgehäuse b eingeschraubt. In der Nähe der Brennstoffdüse a ist ein Kühlraum c, z. B. durch Fräsen, in das Ventilgehäuse b eingearbeitet. An den Kühlraum c sind die I,'-ühlmittelzu- und -abführungskanäle d und e angeschlossen. Die durch das Einarbeiten sich ergebende öffnung ist durch einen zweiteiligen, mit der Ventilgehäüsewand verschweißten Ring/ verschlossen. Um den Kühlraum c reinigen zu können, sind oberhalb desselben mehrere Löcher g angeordnet, die durch Schrauben h verschließbar sind.The injection nozzle a is screwed into the valve housing b. In the Near the fuel nozzle a is a cooling space c, e.g. B. by milling into the valve housing b incorporated. The I, '- ühlmittelzu- and discharge channels are on the cooling space c d and e connected. The opening resulting from the incorporation is through a two-part ring welded to the valve housing wall / closed. In order to be able to clean the cooling space c, several holes g are arranged above it, which can be closed by screws h.
"Durch das Einarbeiten des Kühlraumes von der Mantelfläche des Ventilgehäuses aus ergibt sich der bereits erwähnte Vorteil, daß die nach dem Verbrennungsraum zu liegende Stirnwand aus dem Vollen herausgearbeitet ist, während die Schweißnähte des Verschlußringes f geschützt in dem Zylinderdeckel liegen und nicht den hohen Temperaturen des Verbrennungsraumes ausgesetzt sind. Die Anbringung der öffnungen g, h zum Reinigen macht sich insbesondere dann notwendig, wenn z. B. Seewasser als Kühlmittel verwendet wird."By incorporating the cooling space from the outer surface of the valve housing from the already mentioned advantage arises that after the combustion chamber front wall to be located is worked out from the solid, while the weld seams of the locking ring f are protected in the cylinder cover and not the high one Temperatures of the combustion chamber are exposed. The attachment of the openings g, h for cleaning is particularly necessary when z. B. sea water as Coolant is used.
