Title:
SCROLL-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/137002
Kind Code:
A1
Abstract:
A scroll-type compressor (10) is provided with compression-chamber-forming members (35, 40), a housing (50), an injection passage (44), and an auxiliary introduction mechanism (80). The compression-chamber-forming members form a compression chamber (31). The housing (50) forms an intermediate-pressure-side back pressure chamber (56) which stores refrigerant that exerts back pressure on the compression-chamber-forming members. The injection passage (44) is formed in the compression-chamber-forming members (35, 40) and/or in separate members (50, 90) disposed around the periphery thereof, and is linked to the compression chamber (31). The auxiliary introduction mechanism (80), which is provided to the compression-chamber-forming members, communicates the compression chamber (31) and the intermediate-pressure-side back pressure chamber (56) when the injection pressure, which is the pressure of refrigerant flowing from the injection passage (44) to the compression chamber (31), is higher than the pressure of the back pressure chamber.
