The objective of the present invention is to improve the degree of freedom with respect to the arrangement of an oil separation unit without increasing the physical size of a variable capacitor compressor. Within an arc-shaped upper region of a discharge chamber (142), the two ends (in the direction of the arc) of one space that is defined by a partition member (150) are defined by a first partition wall (104h) and a second partition wall (104i), and a first passage (104f1) is formed partitioned from the other, discharge-chamber-side space. In addition, the central part (in the direction of the arc) of the first passage (104f1) is partitioned by a third partition wall (104j) so as to form a refrigerant flow path having a prescribed opening area. The upstream-side passage part of the first passage (104f1) between the first partition wall (104h) and the third partition wall (104j) communicates with the discharge chamber (142) by means of a second passage (104f2) and functions as an oil separation chamber, and the downstream-side passage part between the second partition wall (104i) and the third partition wall (104j) functions as a connecting passage that communicates with a third passage (104f3), thereby connecting the oil separation chamber and the third passage.
