Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Kühlung und/oder Schmierung einer Hubkolben-Brennkraftmaschine mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a device for cooling and / or Lubrication of a reciprocating internal combustion engine with the features from the preamble of claim 1.
Eine
derartige Vorrichtung zur Kühlung und/oder Schmierung einer
Hubkolben-Brennkraftmaschine ist beispielsweise aus der deutschen
Offenlegungsschrift
Weiter
ist aus der deutschen Offenlegungsschrift
Wenn es nun nicht möglich ist, die Schmiermittelspritzdüsen direkt an den Schmiermittelhauptkanal anzuschließen, ist es von Nachteil, dass für die Vorrichtung zur Kühlung und/oder Schmierung einer Hubkolben-Brennkraftmaschine eine separate Schmiermittelleitung vorzusehen ist.If it is not possible now, the lubricant spray nozzles is to connect directly to the lubricant main channel is it is disadvantageous that for the device for cooling and / or lubrication of a reciprocating internal combustion engine a separate lubricant line is to be provided.
Aufgabe der vorliegenden Erfindung ist es, eine möglichst platzsparende Anordnung für eine gattungsgemäße Vorrichtung aufzuzeigen.task The present invention is a space-saving as possible Arrangement for a generic device show.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the features in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung wird ein äußerst platzsparendes Package ermöglicht.By the embodiment of the invention is an extremely Space-saving package allows.
Durch die Ausgestaltung gemäß Patentanspruch 2 wird ein einfacher und robuster Übertritt des Schmiermittels von der Schmiermittelleitung in die die zweite Schmiermittelleitung erzielt.By the embodiment according to claim 2 becomes a simple and robust transfer of the lubricant from the lubricant line to the second lubricant line achieved.
Durch die Ausgestaltung gemäß Patentanspruch 3 werden die Steuerkräfte für den Steuerkolben des Ventils minimiert.By The embodiment according to claim 3 the control forces for the control piston of the valve minimized.
Die Ausgestaltung gemäß Patentanspruch 4 ist eine besonders bevorzugte Ausführungsvariante, beispielsweise für eine Kennfeldsteuerung.The Embodiment according to claim 4 is a particularly preferred embodiment variant, for example for a map control.
Im Folgenden ist die Erfindung anhand eines besonders bevorzugten Ausführungsbeispieles anhand von zwei Figuren näher erläutert.in the The following is the invention with reference to a particularly preferred embodiment explained in more detail with reference to two figures.
Das
Ventil
Durch
die erfindungsgemäße, quasi „Rohr in Rohr” Ausgestaltung
ist eine ausgesprochen Bauraum sparende Vorrichtung zur Kühlung
und/oder Schmierung der Hubkolben-Brennkraftmaschine dargestellt.
Durch das Einbringen der zweiten Schmiermittelleitung
Weiter
weist das Ventilgehäuse
Durch die erfindungsgemäße Ausgestaltung der Vorrichtung zur Kühlung und/oder Schmierung einer Hubkolben-Brennkraftmaschine wird der Verschleiß im Kurbeltrieb reduziert, wodurch die Lebensdauer der Brennkraftmaschine verlängert wird. Durch den geringeren Schmiermittelbedarf kann eine kleinere Schmiermittelpumpe zum Einsatz kommen sowie eine kleinere Schmiermittelwanne, wobei die Brennkraftmaschine insgesamt nicht größer baut als eine konventionelle Brennkraftmaschine.By the inventive design of the device for cooling and / or lubrication of a reciprocating internal combustion engine the wear in the crank mechanism is reduced, whereby the Life of the internal combustion engine is extended. By the Lower lubricant requirement can be a smaller lubricant pump be used as well as a smaller lubricant trough, wherein the internal combustion engine not larger builds as a conventional internal combustion engine.
