水循環装置。 A main circulation circuit is formed by connecting the radiator with a condescension tank for adjusting the amount of cooling water and the cooling water passage inside the engine body through a pair of water pipes, and the cooling water in this main circulation circuit is The cooling water is circulated as the circulation pump is driven, and one end of a bypass pipe is connected to the outlet side of the cooling water passage in the engine body via a thermostat,
The other end of this bypass pipe is connected to the inlet side of the cooling water passage in the engine body, and when the temperature of the cooling water in the engine body exceeds the set temperature, the thermostat controls the flow of water to the bypass pipe side. In an engine cooling water circulation system in which the inflow of cooling water is blocked, a pressure adjustment pipe is provided that connects the condescension tank and the bypass pipe,
An engine cooling water circulation system characterized in that a check valve for blocking the flow of cooling water from the bypass pipe side to the condescension tank side is interposed in the pressure regulating pipe.
