Abstract
A thermomechanical safety device includes a body and a capsule valve mounted in the body. A volume of auto-ignition material is disposed in the capsule valve, which is moveable between a rest position and a firing position. A spring engages the capsule valve and the body, and biases the capsule valve towards the rest position. A temperature sensitive actuator engages the capsule valve and the body. The temperature sensitive actuator moves the capsule valve between the rest position and the firing position in response to a change in temperature. The temperature to cause the temperature sensitive actuator to move the capsule valve between the rest position and the firing position is less than the ignition temperature of the auto-ignition material.
