ABSTRACT:
A cooling system for water-cooled internal combustion engines, particularly boat motors comprises a pump for circulating cooling water over a heat exchanger and through an expansion vessel, a raw water pump for maintaining a flow of raw water as a cooling fluid through the heat exchanger, a reservoir, and a pressure relief valve and a check valve which are connected in parallel between the expansion vessel and the reservoir. In order to reliably maintain a high pressure in the expansion vessel and to maintain an emergency operation in case of a leak in the cooling system and to accomplish this with simple means, the reservoir is pressure-tight, the line which connects the expansion vessel to the reservoir opens into the uppermost portion of the reservoir, and the raw water pump is connected by a discharge line to the lowermost portion of the reservoir.
