Abstract
An expander-integrated compressor () includes: a compression mechanism () for compressing a working fluid; an expansion mechanism () for expanding a working fluid; and a shaft () that couples the compression mechanism () and the expansion mechanism (). The expansion mechanism () includes a variable vane mechanism (). The variable vane mechanism () controls the movement of a first vane () so that the ratio of a period Pto a period P(P/P) can be adjusted, where Pdenotes the period during which the first vane () is in contact with a first piston () in the course of one rotation of the shaft (), and Pdenotes the period during which the first vane () is spaced from the first piston () in the course of one rotation of the shaft ().
