FIELD: machine building.
SUBSTANCE: invention relates to expansion reservoirs for engine cooling systems. Expansion reservoir (70) for engine cooling system (10) contains first cooling circuit (1) and second cooling circuit (2), wherein the second cooling circuit is configured to operate at a different temperature than the first cooling circuit, while the expansion reservoir is configured to receive the refrigerant and return the refrigerant to the first and second cooling circuits, while the expansion reservoir contains one or more valves (74) configured to control the flow of the refrigerant from the second cooling circuit to the expansion reservoir and / or from the expansion reservoir to the second cooling circuit, depending on the temperature of the refrigerant.
EFFECT: invention provides an expansion of the range of technical tools.
