Flow device in internal combustion engine oil circuit passes predominant flow through heat exchanger in lower, upper temperature ranges, non-predominant flow at intermediate temperature

摘要

The device has a heat exchanger (5) upstream of a filter (3). The heat exchanger can be switched on depending on the oil temp. There are switching positions in which a predominant flow passes through the heat exchanger in the lower and upper temp. ranges and in which a non-predominant flow passes through the heat exchanger in an intermediate temp. range.
