Abstract

Eine Vorrichtung zur Regelung des Kühlwasserkreislaufes für einen Verbrennungsmotor ist mit einem Kühler (12), einem Heizungs-Wärmetauscher (10), mit einer Wasserpumpe (4) und mit einem Thermostatventil (5), das in der Warmlaufphase des Motors oder bei niedrigen Motortemperaturen zwei Kreisläufe ermöglicht, wobei ein Kreislauf zur Kühlung des Motors über eine Bypass-Leitung (7) und ein zweiter Kreislauf zum Heizungs-Wärmetauscher (10) über eine Heizleitung (8) vorgesehen ist, versehen. In der Bypass-Leitung (7) ist ein motordrehzahlabhängig geregeltes Differenzdruckventil (14) angeordnet, wobei in der Warmlaufphase oder in der Phase mit niedriger Motortemperatur bei niedrigen Drehzahlen des Motors die Bypassleitung (7) gesperrt und das gesamte Kühlwasser über die Heizleitung geführt ist und wobei bei höheren Drehzahlen das Differenzdruckventil (14) öffnet und die Bypass-Leitung (7) freigibt, wobei eine mengenmäßige Aufteilung des Kühlwassers in Abhängigkeit von der Auslegung des Differenzdruckventiles (14) über die Bypass-Leitung (7) und die Heizleitung (8) erfolgt.

A device for regulating the cooling water circuit for an internal combustion engine is provided with a cooler (12), a heating heat exchanger (10), with a water pump (4) and with a thermostatic valve (5), which is two in the engine warm-up phase or at low engine temperatures Circulations are made possible, one circuit for cooling the motor via a bypass line (7) and a second circuit for the heating heat exchanger (10) via a heating line (8) being provided. In the bypass line (7) there is a differential pressure valve (14) which is regulated as a function of the engine speed, the bypass line (7) being blocked in the warm-up phase or in the phase with low engine temperature at low engine speeds, and the entire cooling water being conducted via the heating line and whereby at higher speeds the differential pressure valve (14) opens and releases the bypass line (7), a quantitative division of the cooling water depending on the design of the differential pressure valve (14) via the bypass line (7) and the heating line (8) he follows.
