ABSTRACT:
A thermal actuator has a pair of means for containing a vaporizable liquid which communicate with each other, and means within one of the containing means effects only the transfer therefrom of vapor toward the other of the containing means upon the vaporization of at least a portion of the liquid in the one containing means under preselected conditions.
Another thermal actuator has a pair of means for containing a vaporizable liquid which communicate with each other. Means within one of the containing means permits displacement of only a portion of the liquid in its liquid state therefrom to the other of the containing means and effects transfer of at least a portion of vapor vaporized from the remaining liquid in the one containing means under other preselected conditions toward the other containing means.
Methods of controlling the thermal actuators and actuating systems including the thermal actuators are also disclosed.
