Abstract

IN A ROTATING COMPRESSOR, AN OUTER PERIPHERAL SURFACE (40) OF A PARTITION MEMBER (23) WHICH IS SECURED FIRMLY TO A CASING (10) SO AS TO DIVIDE THE INSIDE OF THE CASING (10) INTO A HIGH-LEVEL PRESSURE SPACE AND A LOW-LEVEL PRESSURE SPACE, IS PROVIDED WITH A PERIPHERAL GROOVE (42) FOR ALLOWING FOR SHRINKAGE OF THE CASING (10) AT A WELD AREA WHERE A TRUNK PART (11) AND END PLATE (12) OF THE CASING (10) ARE WELDED TOGETHER. AS A RESULT OF SUCH ARRANGEMENT, THE PARTITION MEMBER (23) IS STRONGLY TIGHTENED BY MAKING UTILIZATION OF SUCH SHRINKAGE , THEREBY NOT ONLY ENHANCING SEALABILITY BETWEEN THE HIGH-LEVEL PRESSURE SPACE AND THE LOW-LEVEL PRESSURE SPACE IN THE INSIDE OF THE CASING (10) BUT ALSO PREVENTING A DROP IN WORKABILITY DURING ASSEMBLING AND AN INCREASE IN COST.(FIG 1)
