エンジン冷却ファンの温度感応型流体継手。A shaft rotatably driven by an engine, a rotor fixed to the tip of the shaft, a housing rotatably assembled on the shaft to house the rotor and working fluid, and a cooling fan attached thereto; a partition member disposed in the partition member that partitions the inside thereof into a working chamber that accommodates the rotor and an oil storage chamber that stores working fluid that flows back from the working chamber; and a valve member that opens and closes a through hole provided in the partition member. In a temperature-sensitive fluid coupling for an engine cooling fan, the valve member is actuated to open the passage hole of the partition member due to a rise in engine temperature, and the working fluid in the oil storage chamber flows into the pre-operating chamber.
The oil storage chamber is provided with a partitioning member that hermetically partitions the inside thereof into a variable pressure chamber and a constant pressure chamber, and a pushing member that moves according to pressure fluctuations in the variable pressure chamber to operate the valve member, while the variable pressure chamber is used for engine use. communicating with a pressure source controlled according to the temperature of the cooling water and communicating the constant pressure chamber with the atmosphere, and opening the through hole of the partition member via the pushing member as the temperature of the engine cooling water rises; A temperature-sensitive fluid coupling for an engine cooling fan, which is characterized by:
