Abstract
A heat management module of a cooling system of an internal combustion engine which has a valve housing that includes at least one first feed connection for cooling water of a bypass circuit and at least one adjacent second feed connection for cooling water of a radiator circuit. The feed connections can be connected to a discharge connection depending on the position of a valve member accommodated in the valve housing. A driving element which actuates the valve member is provided on the valve housing. The driving element is a hydrostatic servo motor, which produces a rotating driving motion and which uses a feed pressure line that branches from the cooling system for pressurization.
