Title:
複数圧縮機の均油システム
Document Type and Number:
Japanese Patent JP4173784
Kind Code:
B2
Abstract:
An oil equalizing system for multiple compressors (11, 12, 13) which does not require a particular machining process for shells (11a, 12a, 13a) of the compressors (11, 12, 13), thereby being capable of preventing an increase in costs, while maintaining oil in each compressor (11, 12, 13) in a proper amount. In a refrigerant circuit, in which at least three compressors (11, 12, 13) are connected in parallel, the oil equalizing system includes an oil equalizing tube (17) adapted to communicate shells (11a, 12a, 13a) of the compressors (11, 12, 13) with one another, and a bypass tube (19) adapted to connect the oil equalizing tube (17) to a discharge side refrigerant line (15) for the compressors (11, 12, 13). The shell (11a, 12a, 13a) of each compressor (11, 12, 13) is directly communicated with the shell (11a, 12a, 13a) of each of the remaining compressors (11, 12, 13) by the oil equalizing tube (17).
