Title:
ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/017281
Kind Code:
A1
Abstract:
The rotary compressor of an embodiment has: a pair of cylinders having cylinder chambers; a plurality of annular partition plates (42, 43); and a rotating shaft. The rotating shaft has a pair of crank eccentric sections (32, 34) and a connection section (33). The plurality of annular partition plates are arranged between the pair of cylinders. The crank eccentric sections are arranged in the cylinder chambers, respectively, of the pair of cylinders. The connection section connects the pair of crank eccentric sections and is disposed inside the plurality of annular partition plates. If the outer diameter of the crank eccentric sections is Dc, the inner diameter of the annular partition plates is Dp, the amount of eccentricity of the crank eccentric sections is e, and the radius of the connection section is Rj, then the relationship of Dp - Dc/2 - e < Rj < Dp/2 is satisfied. Clearances (101, 102) are formed at the ends of the connection section, which face the crank eccentric sections, and the clearances (101, 102) are recessed so as not to protrude further toward the outside radially than the crank eccentric sections. If the axial length of each of the clearances is K and the thickness of the annular partition plate having the greatest thickness among the annular partition plates is T, then the relationship of K < T ≤ K + √(Dp2 - Dc2) is satisfied.
