Actuating device

摘要

The actuator has a cylinder (5) in which there is a piston (3) with a projecting arm (7) that couples to the load element. Springs on both sides (2) are in contact with end plates (4). The end plates are integral with temperature sensitive elements (1,1') and these are located in regions where the temperatures are different. The position of the coupling arm is therefore dependent upon the temperature difference.
