Abstract
A sealed compressor has a sealed casing in which a motor section and a compression section are both accommodated, and also has a pipe connector including at least one sleeve. The sleeve has a first end and a second end opposite to each other. The first end is inserted into a sleeve insertion hole defined in the compression section to allow a refrigerant to flow therethrough, while the second end is hermetically brazed to a copper pipe disposed outside the sealed casing. The sleeve is formed by deep-drawing a copper-plated steel plate into a generally cylindrical shape.
