Document Type and Number:
WIPO Patent Application WO/2017/146167
Kind Code:
A1
Abstract:
In the present invention, two compressors (41, 51) are configured such that respective pistons (45, 55) thereof are in opposite phase to each other. Each piston (45, 55) has a non-circular outer circumferential shape, while each cylinder chamber (60, 70) has an inner circumferential shape determined on the basis of an envelope curve of the outer circumferential surface of the pistons (45, 55) when rotating. The compressor is provided with introduction units (67, 68, 163a, 164a) that introduce an intermediate pressure coolant to the compression chambers (75) of the respective compressors (41, 51).
