Abstract (en)

[origin: WO2015110344A1] To ventilate a heat management system (10) of an internal combustion engine (12), in which coolants circulate in several coolant circuits (36, 46, 50), connected inlets (42, 48, 52) of a rotary valve (20) are opened and closed in a predetermined sequence, in order to ventilate one or more of the coolant circuits (36, 46, 50) in the direction of the compensation tank (22), by means of at least one ventilation circuit (72, 74) which is in fluid connection with a coolant compensation tank (22). Said rotary valve (20) is controlled by means of a control unit (54), wherein a non-connected inlet (60) of the rotary valve (20) is in fluid connection with the coolant compensation tank (22).
