装置。A cavitation erosion prevention device that has an air passage that communicates the air chamber in the water tank provided in the cooling system of a water-cooled engine with the suction side of the water pump, and mixes air bubbles into the cooling water through the air passage. Cavitation erosion prevention, characterized in that the water tank side opening of the air passage is provided at a position below the cooling water level in the water tank when the cooling water expands as the temperature rises. Device.
