Abstract
Description
Die Erfindung betrifft eine Kolbenkühlung für eine Brennkraftmaschine, bestehend aus einer Ölspritzdüse, die mit einem im Kurbelgehäuse in einer Gehäusewand in Längsrichtung verlaufenden Ölverteilerkanal verbunden ist, der einen Anschluss an einen Schmierölkanal hat, aus dem von einem Schaltventil in Abhängigkeit von Betriebsparametern gesteuert Schmieröl in den Ölverteilerkanal eingespeist wird.The The invention relates to a piston cooling for one Internal combustion engine, consisting of an oil spray nozzle, with a crankcase in a housing wall longitudinal extending oil distribution channel is connected, which has a connection to a lubricating oil passage, from that of a switching valve as a function of operating parameters controlled lubricating oil in the oil distribution channel is fed.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Kolbenkühlung so zu verbessern, dass durch eine vereinfachte Anordnung des Schaltventils die Kolbenkühlung insgesamt mit einem geringeren Fertigungsaufwand hergestellt werden kann.Of the Invention is based on the object, the generic piston cooling so to improve that by a simplified arrangement of the switching valve the piston cooling can be produced in total with a lower production cost.
Die Aufgabe ist erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmalen gelöst.The Task is inventively by the features specified in the characterizing part of claim 1 solved.
Die Erfindung hat den Vorteil, dass die besondere Herstellung der Verbindung zwischen dem Hauptschmierölkanal und dem Ölverteilerkanal entfallen kann. Hierdurch wird eine Herstellung der Spritzölkühlung mit einem verringerten Fertigungsaufwand erzielt.The Invention has the advantage that the special production of the compound between the main lubricating oil channel and the oil distribution channel can be omitted. As a result, a production of the spray oil cooling with achieved a reduced manufacturing cost.
Durch die Ausgestaltung gemäß Anspruch 2 wird eine kompakte und kostengünstige Anordnung des Schaltventils als auch der Ölkanäle erzielt.By the embodiment according to claim 2 becomes a compact and inexpensive Arrangement of the switching valve and the oil channels achieved.
Gemäß Anspruch 3 ist von Vorteil, dass die Herstellung der Ölkanäle mit einer Werkzeugaufspannung erfolgen kann. Dadurch ist weiterhin von Vorteil, dass die aufwendige Herstellung von schrägen Bohrungen nicht mehr erforderlich ist.According to claim 3 is advantageous in that the production of oil passages with a tool clamping can be done. This is further advantageous that the complex Production of oblique Drilling is no longer required.
Durch die Ausgestaltung der Aufnahmebohrung als Stufenbohrung gemäß Anspruch 4 kann der Übergang zwischen den Bohrungsabschnitten als Ventilsitz für das Schaltventil genutzt werden. Hierdurch kann das Schaltventil in vorteilhafter Weise baulich vereinfacht ausgeführt werden.By the configuration of the receiving bore as a stepped bore according to claim 4, the transition between the bore portions as a valve seat for the switching valve be used. This allows the switching valve in an advantageous Way structurally simplified become.
Die Ausführung des Schaltventils gemäß Anspruch 5 hat den Vorteil, dass sämtliche Funktionsprüfungen getrennt von der Brennkraftmaschine ausgeführt werden können.The execution the switching valve according to claim 5 has the advantage that all functional tests can be performed separately from the internal combustion engine.
In der Zeichnung werden zwei Ausführungsbeispiele der Erfindung näher erläutert.In The drawing will be two embodiments closer to the invention explained.
