Abstract

Eine Strömungseinrichtung innerhalb eines Ölkreislaufes eines Verbrennungsmotors mit einem Filter, einem Wärmetauscher (17) und einem zumindest teilweise in Abhängigkeit der Temperatur des Kreislauföles arbeitenden Mehrwege-Schaltventil (1), bei der von dem Kreislauföl den Wärmetauscher (17) durchströmt,
- in einem zwischen einem unteren und oberen Temperaturbereich liegenden mittleren Temperaturbereich ein zumindest nicht überwiegender Volumenstromanteil,
- in einem oberen Temperaturbereich zumindest ein überwiegender Volumenanteil,

soll bei einem Betriebszustand in dem unteren Temperaturbereich funktionell erweitert werden.A flow device within an oil circuit of an internal combustion engine with a filter, a heat exchanger (17) and a multi-way switching valve (1) operating at least partially as a function of the temperature of the cycle oil, in which the heat exchanger (17) flows through the cycle oil,
in an average temperature range lying between a lower and upper temperature range, an at least non-predominant volumetric flow rate,
at least a predominant volume fraction in an upper temperature range,

should be extended functionally in an operating condition in the lower temperature range.

Zu diesem Zweck zeichnet sich eine solche Strömungseinrichtung durch folgende Merkmale aus
- durch Schaltstellungen des Schaltventiles (1), nach denen der Wärmetauscher (17) in einem unteren Temperaturbereich in Abhängigkeit des in dem Wärmetauscher (17) auftretenden Ölstrom-Druckverlustes durchströmbar ist und zwar bei einem Druckverlust
- ab einem vorgebbaren, oberen Grenzwert G mit allenfalls einem Volumenstromanteil,
- unterhalb dieses Grenzwertes G mit einem zumindest überwiegenden Volumenanteil.

Figure imgaf001
For this purpose, such a flow device is characterized by the following features
- By switching positions of the switching valve (1), according to which the heat exchanger (17) in a lower temperature range in dependence on the in the heat exchanger (17) occurring oil flow pressure loss can be flowed through at a pressure drop
- from a predefinable, upper limit value G with possibly a volumetric flow rate,
- Below this limit G with an at least predominant volume fraction.
