Abstract
A torque transmitting device is adapted to transmit torque from an input (32) and includes a first member (14), a second member (16) rotatable relative to the first member about an axis of rotation (24), an operating chamber (18) disposed in the first member, a fluid reservoir (70), a fluid passageway (74) communicating with fluid reservoir in the operating chamber and a valve member (82) for controlling the fluid flow through the fluid passageway. A fluid is disposed in the reservoir and is selectively displaceable into the operating chamber through the fluid passageway whereby fluid is positioned in the operating chamber to transmit energy through the fluid from one of the members to the other. A thermostatic ring (90) is connected to the valve member for controlling the position of the valve member and the volume of the fluid in the operating chamber in response to the ambient temperature of the torque transmitting device. A bolt member (36) is provided for mounting the torque transmitting device to the shaft of an engine. The bolt member extends through the first and second members substantially coaxial to the axis of rotation and supports the first and second members for rotation.
