Abstract
A temperature-responsive fluid-type fan coupling has a sealing casing with a partition plate disposed therein. The partition plate divides interior portions of the casing into an oil reservoir chamber and a torque transmission chamber. A port extends through the partition plate to provide communication between the chambers. The casing is rotatably mounted around a rotary shaft such that an end of the shaft is disposed in the torque transmission chamber. A drive disc is fixedly mounted to the shaft and is disposed in the torque transmission chamber. Fluid in the torque transmission chamber functions to transmit torque from the disc to the casing. The valve member has one end mounted to the partition plate and an opposed end movably positioned in proximity to the port through the partition plate. Intermediate portions of the valve member are engaged by a pin, which in turn is movable in response to a temperature-responsive member. The valve member is biased to instantaneously open and close at set temperatures.
