Title:
SCROLL COMPRESSOR
Document Type and Number:
Japanese Patent JP2014234784
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that only a small amount of oil is supplied to compression chambers and thus the sealability between the compression chambers partitioned by a lap is lowered to increase refrigerant leakage and deteriorate the performance.SOLUTION: In a scroll compressor, a compression mechanism part 4 and a motor part 5 are stored in a closed vessel 1. The compression mechanism part 4 includes: a fixed scroll 10; a revolving scroll 11; a driving shaft 13; a main frame 12 which supports the driving shaft 13; and an autorotation restraining mechanism 15. The scroll compressor includes: a first passage 12a for discharging an oil in an oil reservoir space 12d, in which a cylindrical boss part of the revolving scroll 11 of a main bearing member 12m revolves, along an inner wall of the closed vessel; and a second passage 12b for discharging the oil to a rotor upper space 21.
