Abstract

A thermally responsive actuator comprises a barrel (2) which is disposed in an atmosphere in which temperature changes take place. There is a slidable piston (6) within the barrel (2), and a thermally expansive material (6) sealed in the barrel (2), which causes the piston (6) to slide by thermal expansion and thermal contraction due to temperature changes. An extension rod (8) is secured to the piston (6) which slides together with the piston (6). Spring means (10) between relative slide members within the barrel (2) act to cancel the starting frictional force created on the sliding faces.
