Abstract

THE PRESENT INVENTION PROVIDES AN OIL-COOLED TWO-STAGE COMPRESSOR AND A HEAT PUMP CAPABLE OF ENSURING THE CIRCULATION OF OIL AND PREVENTING A DROP IN PERFORMANCE EVEN IF AN INTAKE PRESSURE AND A DISCHARGE PRESSURE FLUCTUATE. THE OIL-COOLED TWO-STAGE COMPRESSOR ACCORDING TO THE PRESENT INVENTION INCLUDES: A FIRST STAGE COMPRESSION SECTION (8) THAT SUCKS A GAS FROM AN INTAKE CHANNEL (12), COMPRESSES THE GAS ALONG WITH OIL, AND DISCHARGES THE COMPRESSED GAS AND OIL TO AN INTERMEDIATE PRESSURE SPACE (14); A SECOND STAGE COMPRESSION SECTION THAT SUCKS A GAS FROM THE INTERMEDIATE PRESSURE SPACE, COMPRESSES THE GAS ALONG WITH OIL, AND DISCHARGES THE COMPRESSED GAS AND OIL TO A DISCHARGE CHANNEL (18); AN OIL SUPPLY CHANNEL (27) THAT SUPPLIES OIL TO A SHAFT BEARING (24) ON A DISCHARGE SIDE OF THE SECOND STAGE COMPRESSION SECTION; AND AN OIL CIRCULATION CHANNEL (28) THAT CIRCULATES OIL FLOWING OUT FROM THE SHAFT BEARING (24) ON THE DISCHARGE SIDE OF THE SECOND STAGE COMPRESSION SECTION (9) TO A CONFINING SPACE THAT IS A SPACE PARTIALLY COMPRESSED IN THE FIRST STAGE COMPRESSION SECTION.
