Title:
LOW-BACKPRESSURE ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/086396
Kind Code:
A1
Abstract:
A low-backpressure rotary compressor (100) comprises a housing (10), a compression mechanism, an oil separator (18) for performing oil-gas separation on a refrigerant discharged from a cylinder (12), and an oil pool (5) for accommodating lubricating oil separated by the oil separator (18). The compression mechanism comprises a cylinder assembly, a piston (13), a slide sheet (14), a main bearing (11) and an auxiliary bearing (12). The cylinder (12) has a slide-sheet chamber (2), the slide-sheet chamber (2) is provided with an oil supply hole, and when the slide sheet (14) moves in a reciprocating manner, the tail end of the slide sheet (14) stretches into or out of the slide-sheet chamber (2) so that the internal volume of the slide-sheet chamber (2) changes between a maximum volume V2 and a minimum volume V1. The oil pool (5) communicates with the oil supply hole via a slide-sheet oil supply path (3). The ratio of the maximum volume V2 to the minimum volume V1 satisfies the following relationship: 35%≤V1/V2≤85%.
