Title:
SCROLL FLUID MACHINE AND REFRIGERATING DEVICE IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2017/043471
Kind Code:
A1
Abstract:
[Problem] To make it possible for a scroll fluid machine that is a single-plate compressor-integrated expander to start easily and reliably and operate stably. [Solution] Coolant compressed in a compressing unit of a scroll fluid machine 1 is suctioned into a compressor on the high-pressure side, and high-pressure coolant compressed by the compressor on the high-pressure side is suctioned into the expander. The invention is provided with: a back pressure chamber 52 formed on a back surface 7c side of a moveable scroll 7, which is the opposite side from a substrate surface 7b; an oil-supply hole 28 and a relief hole 33 by which the back pressure chamber and the discharge side of the compressing unit communicate; a check valve device 66 provided in the supply hole 28, the direction from a compression-side discharge chamber 22 on the discharge side of the compressing unit to a lubricating oil chamber 26 on the rear pressure chamber side is the forward direction; and a relief valve 67 provided in the relief hole 33.
