Abstract

PURPOSE: To form low strain state and obtain long life of a belt by installing the means for reducing the stress applied onto the martensite phase of the belt formed of shape memorizing alloy element, in the captioned engine which heats and cools the shape memorizing alloy efficiently.
CONSTITUTION: The loop shaped memorizing belt 20 formed of shape memorizing alloy is bridged and immersed in the hot water 12 in a hot water tank 11 between pulleys 16 and 18 and heated, then cooled by the cold water 14 in a cold water tank 13 between pulleys 17 and 19. The memorizing belt 20 is bridged in two level crossing state between pulleys 17 and 18 and between oulleys 16 and 19, and in parallel between pulleys 16 and 18 and between pulleys 17 and 19. The conventional belt 21 other than memorizing belt is bridged between pulleys 22 and 23. Thus, the stress applied onto the low temperature phase (martensite phase) of the memorizing belt 20 can be reduced, and generation of strain can be reduced.
