Title:
SCROLL FLUID MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/163628
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a scroll fluid machine that can reliably introduce an intermediate-pressure refrigerant during a compression step and thus can improve compressor efficiency. In the present invention, a scroll compressor (1) is provided with a fixed scroll (18) and a rotating scroll, and has an end plate in which a first bypass port (31) is provided more forward than an injection port (26) when viewed in the direction in which the pressure chamber moves as a result of an orbital rotating movement. The first bypass port discharges, to the outside of a pressure chamber, a refrigerant compressed in the pressure chamber and having at least a prescribed pressure.
