過給機の冷却装置。[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. An electromagnetic switching valve is installed in the communication part of the valve, which switches in conjunction with the cooling water temperature and engine start/stop.
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. 1. A cooling device for an engine-attached supercharger, characterized in that the electromagnetic switching valve is operated by switching the electromagnetic switching valve so that the above-described electromagnetic switching valve is operated.
