Material or fluid expansion utilization device for series expansion motor, has base parts mounted in head to foot manner and with respective shapes to obtain displacement, where each part is displaced with respect to one of other base parts

摘要

The device has base parts that are mounted in a head to foot manner and have respective shapes for obtaining a displacement, where each base part is displaced with respect to one of other base parts. The total displacement of the device is the sum of the displacements of each base part. The base parts (2, 3) are supplied from hot and cold sources (8, 9) respectively, so that displacement of the device occurs in same direction. Heating and cooling functions of the sources (8, 9) are inverted, so that the device is displaced in opposite direction.
