通過後の空気温度に応じて制御している。Figure 5 shows an example of the conventional fan coupling device. J2. 3 is a hollow drive shaft with a pair 4 attached to the drive shaft, and a cooling fan 5 is attached to its outer periphery. 6 is the front end of the drive shaft 1. is fixed to
The inside of the rotor housed in the housing 3 is divided by a partition plate 7 into a storage chamber 8 at the front and a working chamber 9 at the rear in which the rotor 6 is housed. Multi-stage labyrinth grooves 10 and 11 are formed in the outer circumferential edge of the Rohmer and the inner wall of the housing 3 facing thereto, and the labyrinth grooves 10 and 11 engage with each other to obtain viscous resistance of the working fluid between the two. It acts as a. Furthermore, a communication hole 12 is formed in the partition plate 7 to communicate the storage chamber 8 and the working chamber 9. Further, a valve plate 16 that rotates in conjunction with a spiral bimetal 15 provided at the tip of a shaft 14 supported by a bearing portion 13 is disposed in front of the communication hole 12, and after passing through the labyrinth grooves 10 and 11, a valve plate 16 is provided.

１８４７２４号公報等参照）。That is, when the air temperature is low, the valve plate 16 closes the communication hole 12 and stops the circulation of the working fluid. Therefore, the amount of working fluid pumped into the labyrinth grooves io and ti is reduced, and the torque transmitted from the rotor 6 to the housing 3 is therefore reduced, causing the cooling fan 5 to rotate at a low speed. On the other hand, when the air temperature is high, the valve plate 16 opens the flow hole 12 and the working fluid flows from the storage chamber 8 to the working chamber 9. Therefore, there is sufficient working fluid in the labyrinth grooves 10 and 11. Therefore, the torque transmitted from the rotor 6 to the housing 3-\ increases, and the cooling fan 5 rotates at high speed (% opening 6°-

過冷される問題があシ、暖機特性の悪化を招いていた。Problems to be Solved by the Invention However, in the above-mentioned conventional device, the engine is stopped with the valve plate 16 blocking the flow hole 12, and the housing 3 is located at the position of the return passage 17. When stopped in the lower position, the working fluid in the storage chamber 8 flows into the working chamber 9 via the return passage 17, and the working fluid in the working chamber 9
The liquid level L in the storage chamber 8 is as shown in Fig. 3(C).
It will be in a relatively high state, which is the same as . Therefore, immediately after a cold start, the rotational torque of the rotor 7 is transmitted by the working fluid in the working chamber 9, and the housing 3 rotates at a relatively high rotation speed (see the chain line in FIG. 4), causing the cooling fan 15 to blow air. There was a problem with the engine being overcooled, leading to deterioration in warm-up characteristics.
また、ハウジング３の無用な回転にょシ機械的損失は勿
論のこと、回転騒音が発生する。Further, unnecessary rotation of the housing 3 not only causes mechanical loss but also generates rotation noise.

されるのである。According to the present invention having the above configuration, either the front or rear chamber of the storage chamber is not in direct communication with the return passage, so when the engine is stopped, the housing does not move down the return passage. Even if it is stopped in the side position, only the working fluid in the above-mentioned front and rear guides communicating with the return passage will flow into the working chamber, so the liquid level in the working chamber will be low. drop sufficiently. Therefore, the torque transmission from the rotor to the housing immediately after a cold engine start is small, and the housing is prevented from rotating.

The bent outer peripheral edge 19a of the partition wall 19 is fixed to the inner peripheral wall 8a of the storage chamber 8, and the central opening edge 19b is fixed to the outer peripheral surface 13a of the bearing part 13 in a liquid-tight state. Furthermore, one end 17a of the return passage 17 is opened to the working chamber 9, and the other end 17b of the return passage 17 is formed at the side of the front chamber. Furthermore, a small circular communication port n is bored near the outer circumferential edge 19a of the partition wall 19, which is approximately 180 degrees opposite to the position where the return passage 17 is formed.

滑な循環作用が得られる。Hereinafter, the operation of the above embodiment will be explained. First, after warming up, when the valve plate 16 opens the flow hole by the bimetallic mechanism, the rear chamber part 21 of the storage chamber 8 and the pronation of the front chamber part operate. The fluid flows into the working chamber 9 through the circulation hole, transmits the rotational torque from the rotor 6 to the nozzle 3 by viscosity within the labyrinth grooves 10 and 11, and then passes through the return passage 17 and enters the front chamber. be returned. Here, since the working fluid in the anterior chamber pronation is attracted toward the outer circumference by centrifugal force, it quickly flows out from the communication port n into the rear chamber 21, resulting in a smooth circulation effect.

て、冷却ファン５の回転数を低く抑えることができる。On the other hand, when the engine is stopped with the valve plate 16 blocking the communication hole 12 and the nozzle 3 is stopped with the return passage 17 in the lower position (the position shown in FIG. 1), (the communication port is (upper position), the working fluid in the front chamber flows backward into the working chamber 9 from the return passage 17, but the working fluid in the rear chamber 21 flows through the partition as shown in FIG. Board 7
A small amount of liquid flows into the working chamber 9 from the hole 18, but a large amount is stored up to the high liquid level L up to the lower edge of the hole 18. Therefore, only a small amount of working fluid is stored in the working chamber 9 at the same level as the low liquid level L in the front chamber, as shown in FIG. Therefore, the transmission of rotational torque from the rotor 6 to the nozzle 3 immediately after a cold engine start is extremely small, so that the high rotational rotation of the nozzle 3 is sufficiently prevented as shown by the solid line in FIG. The rotation speed of the fan 5 can be kept low.
