Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/124111
Kind Code:
A1
Abstract:
A scroll compressor (100, 200), comprising: a compression mechanism (CM), comprising a fixed scroll member (20, 220) and an orbiting scroll member (30, 230), the orbiting scroll member (30, 230) being capable of axially shifting between an engagement position and a disengagement position, the orbiting scroll member (30, 230) and the fixed scroll member (20, 220) being axially engaged with each other at the engagement position so as to form a series of compression chambers (C1, C2, C3) for compressing fluid, and the orbiting scroll member (30, 230) and the fixed scroll member (20, 220) being axially disengaged from each other at the disengagement position; a main bearing seat (50, 250), suitable for supporting the compression mechanism (CM); a back pressure chamber (B), formed between the orbiting scroll member (30, 230) and the main bearing seat (50, 250), communicated with at least one compression chamber (C2) via a communication channel (35, 235) provided in the orbiting scroll member (30, 230) or the fixed scroll member (20, 220), and suitable for exerting a back pressure on the orbiting scroll member (30, 230) so as to bias the orbiting scroll member (30, 230) to the engagement position; and a first sealing apparatus (180, 180a, 180b, 280), provided between the back pressure chamber (B) and a gas suction area of the compression mechanism (CM), and capable of keeping sealed when the orbiting scroll member (30, 230) axially shifts. The scroll compressor can improve the efficiency and reduce the power consumption.
