機の冷却装置。[Scope of Claim for Utility Model Registration] It has a circulating water circuit for cooling the supercharger that branches off from the engine cooling water path and circulates a part of the cooling water to the cooling part of the supercharger. , a water storage section is formed at a position higher than the supercharger cooling section and in communication with the cooling water passage, and the water storage section has an inlet side and an outlet side passage and a cooling water passage of the supercharger cooling section. A switching valve that is switched and operated depending on the temperature of the cooling water is installed in the communication part of the water storage part, and the upper part of the water storage part and the water inlet part having a pressure regulating valve on the upper part of the radiator are connected. A solenoid valve is installed that opens and closes depending on the temperature of the cooling water flowing out from the cooling section of the engine.
A circulating water circuit passing through the water storage section is formed, and
When the cooling water exceeds the set temperature, a circulating water circuit is formed that bypasses the water storage section, and when the engine is stopped, a circulating water circuit is formed in which the low-temperature cooling water held in the water storage section flows into the cooling section of the supercharger. A cooling device for an engine-attached supercharger, characterized in that the switching valve is operated by switching the switching valve so that
