Abstract
An apparatus for moving a controlled member, as for example a valve, to a predetermined position in response to temperature conditions includes a bearing member which overcomes a force exerted by an energy storage device within a predetermined temperature range. The bearing member includes a fusible material which melts in another predetermined temperature range to enable the force exerted by the energy storage device to overcome the bearing member and to move the controlled member to a fail-safe position.
