Title:
TWO-STAGE COMPRESSION TYPE COMPRESSOR AND REFRIGERATING DEVICE USING IT
Document Type and Number:
Japanese Patent JP3594570
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a two-stage compression type compressor and a refrigerating device using such a compressor whereby it is possible to adjust the oil mixing ratio to the discharge refrigerant.
SOLUTION: The two-stage compression type compressor 1 is equipped with first passages 19 and 23 to lead the refrigerant compressed at the first stage 15 to the intermediate pressure directly to a suction port 17A at the second stage 17 and second passages 21 and 23 to discharge the intermediately compressed refrigerant into a shell case 11 and lead to the suction port 17A of the second stage 17 through inside the shell case 11, wherein the refrigerant with the intermediate pressure led to the second stage suction port is discharged upon compressing to a higher pressure at the second stage. A regulator valve 25 to adjust the amount of the refrigerant led directly to the second stage suction port 17A is installed in the first passage 19.
