ABSTRACT:
Disclosed is a temperature-sensing type fluid fan coupling device including: a rotary shaft; a sealing enclosure box having a casing and a cover fitted with a cooling fan; a partition plate partitioning the sealing enclosure box into an oil reserving chamber and a torque transfer chamber accommodating a driving disk; a dam formed in a part of the sealing enclosure box; a circulation passageway leading from the torque transfer chamber to the oil reserving chamber; a valve member fixed to the partition plate, the other end thereof acting to open the hole if an ambient temperature exceeds a set value but close the hole if lower than the set value, the valve interlocking in response to deformations of a temperature-sensing member with variations in temperature; and a torque transfer gap between the driving disk and the confronting wall surface in the vicinity of the cover and the casing, the gap having a oil contact area increased or decreased to control the torque transfer. Based on this construction, a weight member is provided close to the valve member. A plug member assumes a tapered oblique shape to fit in the hole.
