Abstract (en)
[origin: EP1035307A1] The cooling controller can prevents the problem such as overheating of the internal combustion engine and, thus, can exhibit a secure fail safe function. A spring member (45) in a coil form is wound round the valve shaft (27) of the butterfly valve (26) Both ends thereof are communicated with a pair of pin members (27a and 27b) standing on the valve shaft (27) respectively. The pin member (27a) which is made of a material which fuses and breaks at a prescribed temperature is fused and broken, when the cooling water is heated up to a prescribed temperature. As a result, one end (45a) of the spring member (45) comes into contact with the communication pin (25a) projecting toward the valve shaft (25) due to the return force of the spring member (45), and due to the counteraction, the valve shaft (27) is caused to rotate in the direction of opening the valve. Consequently, it is possible to circulate the cooling water and, thus, the problem such as overheating of the engine can be prevented. <IMAGE>
