Title:
SEALED ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/065706
Kind Code:
A1
Abstract:
With a sealed rotary compressor of an embodiment of the present invention, when the total cross-sectional area of connecting passages that are provided from an auxiliary bearing to a main bearing and that enable high-pressure gas within a second muffler to converge with high-pressure gas within a first muffler is S1 [mm2], and the total surface area of a sealed-case-internal discharge part which is provided on the first muffler is S2 [mm2], S2 is set so as to be greater than S1 (S1 < S2), and when the distance from one end surface of the stator in an electric motor unit to one end surface of the sealed case is A and the distance from the other end of the stator to the other end of a member (for example, a first cylinder) which fastens a compression mechanism unit to the sealed case is B, then 0.5 < B/A < 1 . . . (1).
