ABSTRACT:
The invention relates to a valve combination which is characterized in that the valve combination has a passive valve and an active valve. The active valve is provided with means for an active influence of the control position of a closing element and regulates the fluid flow at a high pressure. The passive valve controls the fluid flow at low pressure. The passive valve and the active valve are integrated into the cooling system pump circuit such that the pressure difference between the high and low fluid pressure and the control positions of the active valve determine the control position of the passive valve.
