Abstract

A combustion machine comprising an internal combustion engine and a cooling system that has a coolant pump, a main cooler, a heating heat exchanger, a bypass which bypasses the heating heat exchanger, coolant ducts in the internal combustion engine, and a regulating device with an actuator which serves for the regulated distribution of a coolant as a function of at least one local coolant temperature. The invention is characterized in that, when the actuator is actuated in one direction, the regulating device—when it is in a first position, allows coolant flow through the internal combustion engine and the heating heat exchanger, and prevents coolant from flowing through the bypass and the main cooler;—when it is in a second position, additionally allows coolant to flow through the bypass; and—when it is in a third position, additionally allows coolant to flow through the main cooler.
