Title:
COUNTERWEIGHT, COUNTERWEIGHT ASSEMBLY AND SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/083312
Kind Code:
A1
Abstract:
A counterweight assembly for a scroll compressor and the scroll compressor (10). The counterweight assembly comprises a bushing (200) and counterweights (100, 400) mounted on the bushing. A driving shaft (30) of the scroll compressor (10) drives a moving scroll (160) of the scroll compressor (10) by means of the bushing (200). The counterweights (100, 400) comprise counterweight portions (300, 500), and the counterweight portions (300, 500) comprise front end portions (310, 510) and tail end portions (320, 520) relative to the rotation direction of the counterweight assembly. The counterweight portions (300, 500) are configured so that the radial distances from outer peripheral edges of the counterweight portions (300, 500) to the center of the counterweight assembly are variable from the front end portions (310, 510) to the tail end portions (320, 520). The present structure may flexibly change the shape of the counterweight and the location of the center of mass so as to reduce gas power consumption and improve oil circulation.
