Embodiment Construction
[0028] like Figure 1-2 As shown, the present invention provides a balance weight 1 of a rotary compressor, which includes a balance weight bottom plate 11 in the shape of a flat disk and having upper and lower circular surfaces. The center of circle of the disc-shaped balance weight bottom plate 11 is oppositely arranged (preferably in 180 ° of rotation or arranged symmetrically to the center) of the balance weight main eccentric portion 12 and the balance weight secondary eccentric portion 13 (that is, the balance weight is set on the upper circular surface During the main eccentric part, the balance weight secondary eccentric part is set on the lower circular surface; when the balance weight secondary eccentric part is set on the upper circular surface, the balance weight main eccentric part is set on the lower circular surface), and the balance weight bottom plate 11. The main eccentric portion 12 of the balance weight and the auxiliary eccentric portion 13 of the balance ...
