Description
Schmierölkreislauf für Brennkraftmaschinen Die Erfindung bezieht sich auf einen Schmierölkreislauf für Brennkraftmaschinen mit einem kombinierten Überdruck-Thermostat-Ventil zwischen der Druckpumpe und dem Ölkühler und besteht darin, daß das Überdruckventil mit dem Einschalten des Ölkühlers durch den Thermostaten in den Ölstrom zwischen Ölpumpe und Schmierstellen selbsttätig von der Druckleitung abgeschaltet wird.Lubricating oil circuit for internal combustion engines The invention relates to on a lubricating oil circuit for internal combustion engines with a combined overpressure thermostatic valve between the pressure pump and the oil cooler and consists in that the pressure relief valve when the oil cooler is switched on by the thermostat in the oil flow between The oil pump and lubrication points are automatically switched off by the pressure line.
Es ist bekannt und üblich, in den Ölkreislauf von Brennkraftmaschinen Überdruckventile einzubauen, um den Öldruck im Schmierungssystem unabhängig von Temperatur, Ölviskosität, Drehzahl und Lagerspiel auf einer bestimmten, durch das Ventil vorgegebenen Höhe zu halten. Ferner ist es bekannt, bei hochbelasteten Brennkraftmaschinen, insbesondere bei luftgekühlten Maschinen, einen Ölkühler zu verwenden, um eine unzulässig hohe Erhitzung des Schmieröls zu verhindern. Diese Ölkühler werden vielfach durch thermostatisch gesteuerte Ventile beeinflußt und erst bei Erreichung einer bestimmten Öltemperatur voll in den Ölkreislauf eingeschaltet.It is known and common in the oil circuit of internal combustion engines Install pressure relief valves to keep the oil pressure in the lubrication system independent of Temperature, oil viscosity, speed and bearing clearance on a certain, through the Keep the valve at the specified height. It is also known, in highly loaded internal combustion engines, To use an oil cooler, especially with air-cooled machines, is not permitted to prevent excessive heating of the lubricating oil. These oil coolers are going through many times influenced by thermostatically controlled valves and only when a certain one is reached Oil temperature fully switched on in the oil circuit.
Die heute allgemein verwendeten Ölüberdruckventile haben den Nachteil, daß sie unabhängig von der Öltemperatur arbeiten. Sie reduzieren den Öldruck auch bei hohen Öltemperaturen, obwohl gerade dann ein höherer Öldruck und damit eine vergrößerte Durchflußmenge für die nicht nur zu schmierenden, sondern auch zu kühlenden Motorlager durchaus erwünscht ist. Es tritt also gerade dann ein Druckabfall in der Ölleitung auf, wenn vom Motor Öl bzw. besonders viel Öl benötigt wird.The oil pressure relief valves commonly used today have the disadvantage that they work independently of the oil temperature. They also reduce the oil pressure at high oil temperatures, although just then a higher oil pressure and thus a increased flow rate for not only to be lubricated, but also to be cooled Motor mount is quite desirable. So just then a pressure drop occurs the oil line when the engine requires oil or a particularly large amount of oil.
Erfindungsgemäß ist das Ölüberdruckventil mit dem thermostatisch gesteuerten Ventilschieber kombiniert, so daß bei höheren Öltemperaturen das Überdruckventil außer Funktion gesetzt und somit eine Schmierung und Kühlung der Motorlager erreicht wird, die der höheren Belastung des Motors angepaßt ist.According to the invention, the oil pressure relief valve is thermostatically controlled Valve slide combined, so that at higher oil temperatures the pressure relief valve put out of function and thus a lubrication and cooling of the motor bearings is achieved which is adapted to the higher load on the engine.
Ein weiterer Vorteil der Erfindung besteht darin, daß die beiden verschiedenen Ventile, nämlich das Ölüberdruckventil und das thermostatisch gesteuerte Ventil für die Zuschaltung des Ölkühlers vereinigt sind und somit ein Aggregat geschaffen ist, das die Bedingungen einer Fertigungsautomatisierung erfüllt, da der von einem Thermostaten betätigte Steuerschieber eine Fertigungs- und Montageeinheit bildet, in einer einzigen Prüfvorrichtung funktionsgeprüft werden und schließlich im Ersatzteillager als ein geschlossenes Aggregat geführt, registriert und repariert bzw. ausgetauscht werden kann.Another advantage of the invention is that the two different Valves, namely the oil pressure relief valve and the thermostatically controlled valve are combined for the connection of the oil cooler and thus created an aggregate is that fulfills the conditions of a factory automation, since that of a Thermostat actuated spool forms a manufacturing and assembly unit, are function-tested in a single test device and finally in the spare parts store managed, registered and repaired or replaced as a closed unit can be.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in einem Längsschnitt schematisch dargestellt. Hierbei ist der Kanal 8 die von der Zahnradölpumpe 2 kommende, der Kanal 11 die zu den Lagerstellen 13, 14, 15 und der Kanal 12 die zum Ölkühler 3 führende Leitung. Die in das Motorengehäuse 1 eingeschraubte Steuerschieberbüchse 4, die zwei parallele, radiale Bohrungen aufweist, bildet zusammen mit dem Steuerschieber 5, der die zu den Bohrungen der Büchse 4 gleichgerichteten Kanäle 9 und 10 aufweist, dem in dem in das Motorengehäuse hinweisenden, glockenförmig ausgebildeten Teil des Schiebers 5 untergebrachten Überdruckventil 6 und dem mit dem nach außen weisenden Teil des Schiebers 5 verbundenen Thermostaten 7 eine Montageeinheit. Bei kaltem Motor und kaltem Öl ist der Thermostat 7 vollständig zusammengezogen und befindet sich in Anfangsstellung. Die Ölpumpe 2 fördert das Öl unter Druck durch den Hauptkanal 8 und den nun freigegebenen Schieberkanal9 direkt zu den Lagerstellen 13, 14, 15. Ein zu hoher Öldruck wird über das Überdruckventil 6 abgebaut, indem das überschüssige Öl direkt in" das Kurbelgehäuse abfließt. Wird mit zunehmender Motorbelastung das Öl auf eine bestimmte Temperatur erwärmt, dehnt sich der Thermostat 7 aus und drückt den Steuerschieber 5 nach unten, wodurch der Kanal 9 allmählich geschlossen, der Kanal 10 jedoch allmählich geöffnet und der Weg zum Kanal 12 und damit zum Ölkühler 3 mehr und mehr freigegeben wird. Das überdruckventil6 wird außer Betrieb gesetzt, sobald der Kanal 9 völlig geschlossen und somit nicht mehr in den Kreislauf eingeschaltet ist.In the drawing, an embodiment of the invention is in one Longitudinal section shown schematically. Here the channel 8 is that of the gear oil pump 2 coming, the channel 11 to the bearings 13, 14, 15 and the channel 12 the Line leading to the oil cooler 3. The control slide sleeve screwed into the motor housing 1 4, which has two parallel, radial bores, forms together with the control slide 5, which has the channels 9 and 10 aligned with the bores of the sleeve 4, that in the bell-shaped part pointing into the motor housing of the slide 5 housed overpressure valve 6 and the one with the outward-facing Part of the slide 5 connected thermostat 7 an assembly unit. When it's cold Engine and cold oil, the thermostat 7 is completely contracted and located in the initial position. The oil pump 2 conveys the oil under pressure through the main channel 8 and the now released slide channel 9 directly to the bearing points 13, 14, 15. Too high an oil pressure is reduced via the pressure relief valve 6 by removing the excess Oil flows directly into "the crankcase. If the engine load increases When oil is heated to a certain temperature, the thermostat 7 expands and presses the control slide 5 down, whereby the channel 9 gradually closed, the Channel 10, however, gradually opened and the way to channel 12 and thus to the oil cooler 3 is released more and more. The pressure relief valve6 is put out of operation, as soon as the channel 9 is completely closed and thus no longer switched on in the circuit is.
