Claims (1)
とウォータポンプ吸込側とを連通ずる空気通路を設ける
と共に、冷却水温度に応じて開閉し冷却系統のラジェー

特徴とするキャビテーションエロージョン防止装置。In a water-cooled engine, an air passage is provided that communicates the air chamber provided in the cooling system with the water pump suction side, and also opens and closes depending on the cooling water temperature to connect the radiator side of the cooling system and the bypass passage side of the radiator. A cavitation erosion prevention device characterized in that a passage opening/closing valve that opens and closes at a cooling water temperature lower than the operating temperature of a thermostat for switching the cooling water is interposed in the air passage.
