Abstract
A temperature-sensing fan fluid coupling for use with an automobile engine. The coupling comprises a sealed enclosure, a partition plate having an outflow control hole, a thermostat mounted upon the front surface of the enclosure, a rodlike link member in contact with the thermostat at its one end, an interlocking member against which the link member bears, and a resilient tonguelike valve member. One end of the valve member is fixed, while the other end is in resilient contact with the front end of the interlocking member. The thermostat is connected to the valve member via the link member and the interlocking member. As the ambient temperature changes, the thermostat deforms to cause the valve member to more or less open the hole.
