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 plurality of water storage parts are formed at a position higher than the supercharger cooling part and in communication with the cooling water passage, and cooling water of the inlet side and outlet side passages of the plurality of water storage parts and the supercharger cooling part is formed. An electromagnetic switching valve that is switched in conjunction with the cooling water temperature and engine start/stop is installed in the communication section with the passage, and the multiple water storage sections are connected to the radiator at a position higher than the radiator in the engine cooling water path. The upper part communicates with the engine cooling water path and the supercharger cooling water path, and depending on the engine operating condition or the set temperature of the cooling water during engine operation, a circulating water circuit is formed that passes through one water storage section, and the other. 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 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 it operates by switching.
