Claims

[Scope of utility model registration request]

A sealing device that is supported on a rotating shaft and has a fan member mounted on the outside to control the rotation transmitted from the driving part to the driven part by the viscosity of the fluid according to changes in the external ambient temperature. The interior of the box is divided into an oil sump chamber and a torque transmission chamber by a dividing plate, and an inflow adjustment hole provided on the dividing plate on the oil sump chamber side is attached to the outside front of the box to open and close it. In addition to incorporating a plate-shaped valve member that interlocks with the thermosensor, 1
, A driving disk fixed to the end of the rotating shaft body is installed in the torque transmission chamber side with a slight gap between the opposing wall surface inside the casing including the dividing plate for Herk transmission, and further inside the gap. In order to increase or decrease the effective contact area for the amount of oil in accordance with a desired constant change in external ambient temperature, oil is collected on the opposite circumferential wall surface on the container casing side, which is the outer circumferential wall surface of the driving disk due to centrifugal force during rotation. In a fan coupling device in which a dam having a pumping function and a circulation flow path adjacent to the dam are connected from a torque transmission chamber to an oil reservoir chamber, an inflow adjustment hole provided on the dividing plate is provided. , a plurality of valves are provided adjacent to each other at positions successively farther outward from the axis in the opening direction of the valve member within the surface area on which the plate-shaped valve member slides, and have a function of opening and closing the inflow adjustment hole. In order to slide the member from side to side, it is linked with a thermosensor made of a spiral bimetallic material whose one end is attached to the outside front of the container case, and thus the valve member allows the flow to flow in response to changes in the external ambient temperature. Closing or sequentially opening the adjustment holes,
Alternatively, a temperature-sensitive fluid type fan coupling device characterized in that both holes are opened and rotation of the fan on the driven part side is controlled in a plurality of stages.
