Abstract

PURPOSE:To obtain a fan speed of rotation suitable for the operational condition, by controlling a flow of the operating fluid from reservoir tank to operating room, in the method of appropriately open-close operating each link hole of the coupling housing by a control plate correspondingly operating to the bimetal. CONSTITUTION:In accordance with a change of radiator passing air temperature from low to high temperature, though both of a first link hole 15 and a second link hole 16 are being closed, as the temperature changes to high the first link hole 15 is opened overlapping to a first control hole 22, and as the temperature goes further high the second link hole 16 is opened overlapping to a second control hole 23, simultaneously with an opening area of the first link hole 15 gradually decreased. In a front housing 2a is provided a return path 24 linking to a reservoir tank 7 from the peripheral edge part of an operating room 8, and the operating fluid, flowing into the operating room 8 from the tank 7, goes through the path 24 to return to the tank 7, circulating between the tank 7 and the room 8.
