Abstract
A temperature activated valve is provided comprising a trigger for effecting actuation of the valve. The trigger includes a temperature responsive trigger portion including a plurality of constituent trigger segments connected to one another in series. The constituent trigger segments include a plurality of temperature responsive trigger segments. Each one of the temperature responsive trigger segments, independently, includes a composite material, the composite material including: (a) a shape changing material-comprising component configured to assume a change in shape in response to receiving of heat energy by the temperature responsive trigger segment, and (b) a relatively inelastic material-comprising component having a modulus of elasticity that is greater than the modulus of elasticity of the shape changing material-comprising component.
