PROBLEM TO BE SOLVED: To make the target machinery make motions proportionally in response to the temperature change by utilizing expansion/contraction of a motive liquid with a large coefficient of thermal expansion with a small and simple transmission mechanism or without using the mechanism. SOLUTION: A first chamber 4 in a housing 1 divided by a movable partition member 3 is filled with the motive liquid M with a large coefficient of thermal expansion, and a second chamber 5 is filled with an operation liquid W with lubricity. The second chamber 5 is made to communicate with an operation chamber 16 of a cylinder 11. The partition member 3 is compressed with the expansion force of the motive liquid M generated from the temperature rise and the operating liquid W in the second chamber 5 is moved to the operation chamber 16 to push a piston 14, so that the target machinery is made to move linearly according to the temperature change. The stroke and force applied to the piston 14 can be arbitrarily set based on the ratio of the effective area of the partition member 3 to that of the piston 14. COPYRIGHT: (C)2003,JPO
