Abstract

Die Erfindung betrifft ein Flüssigkeitssystem für eine durch einen Turbolader (2) aufgeladene Brennkraftmaschine (1), wo­ bei der Turbolader über eine Vorlaufleitung (4) und eine Rücklaufleitung (6) mit dem Kühlkreislauf der Brennkraftma­ schine verbunden ist und im Betrieb der Brennkraftmaschine eine Zwangsumlaufkühlung erfolgt, sowie das Kühlsystem einen Ausgleichsbehälter (8) für die Kühlflüssigkeit aufweist. The invention relates to a fluid system for a a turbocharger (2) supercharged internal combustion engine (1) where in the turbocharger via a flow line (4) and a Return line (6) with the cooling circuit of the internal combustion engine Machine is connected and in the operation of the internal combustion engine forced circulation cooling takes place, and the cooling system one Has expansion tank (8) for the coolant.

Um sicherzustellen, daß die Kühlung des Turboladers nach dem Abschalten der Brennkraftmaschine ohne Zuhilfenahme einer nachlaufenden Umwälzpumpe mit einem hohen Wirkungsgrad er­ folgt, wird erfindungsgemäß vorgeschlagen, daß sich in der Vorlaufleitung des Turboladers ein Rückschlagventil (5) be­ findet und die Rücklaufleitung des Turboladers verzweigt aus­ gebildet ist, in eine erste Leitung (10), die oberhalb des Kühlmittelspiegels (12) in den Ausgleichsbehälter mündet sowie eine zweite Leitung (11), die unterhalb des Kühlmittelspiegels in den Ausgleichsbehälter mündet und ein Rückschlagventil (7) enthält. To ensure that the cooling of the turbocharger after the Switching off the internal combustion engine without the aid of a trailing circulation pump with a high efficiency follows, it is proposed according to the invention that in the Flow line of the turbocharger a check valve (5) be finds and branches off the return line of the turbocharger is formed in a first line (10) above the Coolant level (12) opens into the expansion tank as well a second line (11) below the coolant level opens into the expansion tank and a check valve (7) contains.

Bei dem erfindungsgemäßen Kühlsystem führt ein Abschalten der Brennkraftmaschine dazu, daß das Kühlmittel im Turbolader auf­ geheizt wird, verdampft und die dampfförmige Phase die flüs­ sige Kühlmittelphase mehr oder weniger in den Ausgleichsbe­ hälter ausstößt. Dies führt zu einem Druckunterschied am Rück­ schlagventil der Vorlaufleitung, so daß Kühlflüssigkeit aus dem System durch die Vorlaufleitung (4) zum Turbolader (2) nachläuft. Der zyklische und schubweise Vorgang endet erst, wenn das Lager des Turboladers auf Kühlmittelsiedetemperatur abgekühlt ist. In the cooling system according to the invention, switching off the Internal combustion engine causes the coolant in the turbocharger is heated, evaporated and the vapor phase flows coolant phase more or less in the compensation area ejects. This leads to a pressure difference at the back Check valve of the flow line so that coolant is out the system through the flow line (4) to the turbocharger (2) runs after. The cyclical and batch process only ends when the turbocharger bearing is at coolant boiling temperature has cooled down.
