Abstract
A valve member of a temperature sensitive fluid fan coupling for an engine cooling fan is formed from a plate material having a weight provided at its free end. The modulus of section of the longitudinally central portion of the plate material is reduced to impart flexibility thereto so that it is flexible in the direction of rotation. Accordingly, it is possible to enhance the effect of the action of the weight which causes the valve member to be displaced so as to cancel the pivotal displacement of the valve member caused by the displacement of a bimetal. Thus, it is possible to eliminate the discontinuity in the temperature sensitivity of the speed of rotation of the fan and hence lower the noise level, reduce the fuel consumption and minimize the change in temperature of cooling water.
