PURPOSE:To obtain large output by a structure wherein a working member made of configuration memory alloy is attached parallel to a fixed block and a moving block and the moving block is encircledly provided with a water guide frame for warm and cool waters and at the same time jointed to the piston of a hydraulic cylinder. CONSTITUTION:The plate type working member 11 made of configuration memory alloy is stationarily attached to the fixed block 13 at one end and to the moving block 14 at the other end thereof. The water guide frame 15 for supplying hot water and cold water to the member 11 is provided at the exposed part of the member 11 laying between both the blocks 13 and 14. The moving block 14 is coupled to the piston 17 in a cylinder block 16. When the hot water is supplied to the water guide frame 15, the working member 11 contracts itself, resulting in moving the piston 17 leftward and generating high pressure within the cylinder 18 and yet storing said high pressure within a pressure accumulator 21. On the other hand, when the cold water is supplied to the water guide frame 15, the working member 11 extends itself, resulting in moving the piston 18 rightward and introducing the oil within a tank 19 into the cylinder 18. |
