PURPOSE:To decrease the horsepower consumption, and improve the warming up performance of an engine by preventing of suppercooling by a method wherein a temperature sensing body is provided for the simultaneous controlling of the rotary speed of a fan and an impeller with a cooling water temperature response type fluid coupling. CONSTITUTION:At the operation of an engine, a rotor 15 at the driving part side is rotated via a pulley 4. In case of the low temperature of a cooling water, a piston 9a is deviated toward the right direction with a temperature sensing body 9, then a valve 16 closes an inflow adjusting hole 12a with a spring 17. Therefore, an oil in a transferring chamber 14 is flowed through a circulating passage 19 communicated to an oil reservoir chamber 13 side via a dam 18 by the centrifugal force due to the rotation of the rotor 15, thus, the pumping action is generated by the flowing oil. The oil volume in the transferring chamber 14 is decreased, the rotation of a cooling fan 6 at the driven side and an impeller 7 is slowed down. On the other hand, as the cooling water temperature is raised, the rotation of the cooling fan 6 and the impeller 7 is increased due to the inverse action described above, an air flow is made to be blown and the cooling water is made to be circulated satisfactory by the engine. |
