とを含む冷却液循環回路と、前記冷却液循環回路の途中
に設けられ共通のポンプ軸を内燃機関により駆動される
ことにより互いに並列の関係にてポンプを行う第一のポ
ンプ及び第二のポンプと、前記冷却液循環回路を流れる
冷却液の温度が所定値以下の時にのみ前記第二のポンプ
の吐出ポートを前記ウォータジャケットをバイパスして
前記冷却液循環回路の途中に接続する流路切換装置とを
有する内燃機関の冷却装置。A coolant circulation circuit including a water jacket and a radiator provided in the engine body and a common pump shaft provided in the middle of the coolant circulation circuit are driven by an internal combustion engine to operate the pumps in parallel with each other. Only when the temperature of the coolant flowing through the coolant circulation circuit is below a predetermined value, the discharge port of the second pump bypasses the water jacket and circulates the coolant.
