Document Type and Number:
Japanese Patent JP2015068262
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary compressor capable of solving a problem that oil is excessively supplied to a second rotary compression element, by a simple structure.SOLUTION: A rotary compressor includes: an intermediate partitioning plate 36 for partitioning rotary compression elements 32 and 34; an oil hole 13 formed on a rotary shaft 16; a through-hole 131 formed on the intermediate partitioning plate 36, and opening to the oil hole 13 side on the inner side and on a sealed container 12 side on the outer side; and a communication hole 133 for communicating the through-hole 131 and a suction side of the second rotary compression element 34. The through-hole 131 is composed of a small diameter hole portion 131A on the oil hole 13 side, and a large diameter hole portion 131B having a diameter larger than that of the small diameter hole portion 131A on the sealed container 12 side.
