Title: ENGINE COOLING DEVICE, AND ENGINE SYSTEM
Abstract:
An engine cooling device (3) in which a flow path switching unit (6) provided between a radiator (5) and the outlet (EFb) of a cooling flow path (EF) and between a pump (4) and the outlet (EFb) of the cooling flow path (EF) is provided with valves (16) for switching to a radiator-connecting flow path (22) or to a bypass flow path (23) depending on the temperature of cooling water (W), and a sleeve (17) connected in parallel to the valves (16) and for causing the cooling water (W) to flow to both the bypass flow path (23) and the radiator-connecting flow path (22).
