Abstract
The present disclosure provides a thermal actuator which comprises at least two containers containing a first fluid. The at least two containers define interior portions that are interconnected such that the interior portions of the containers are in fluidal communication with each other. The first fluid comprises a first liquid component and a second gaseous component. The thermal actuator is arranged such that a change in a temperature difference between one container and the or another container and within a predetermined range of temperature difference causes a quantity of a fluid contained in the thermal actuator to be transferred from the one container to the or another container such that a mass distribution of the thermal actuator is altered in response to the change in temperature difference so as to cause actuation.
