Abstract
A fluid coupling apparatus has a three stage control for torque transmission. The apparatus has two slots, of which one slot is opened when the temperature reaches a first set temperature. The other slot is opened at a second set temperature. The latter slot has a shape which increases the opening gradually in accordance with the movement of a valve member so that the torque transmission is gradually increased from the second torque transmission state to the third torque transmission state.
