Pipe connection structure of a compressor

摘要

A closed type compressor has a casing, a compression mechanism section housed in the casing, an intake pipe member which extends through a burring hole in the casing and which is connected to an intake port of the compression mechanism section, an annular pipe insertion member airtightly bonded to a peripheral edge of the burring hole, and a tubular member fitted into an inner peripheral surface of the pipe insertion member and airtightly bonded to this inner peripheral surface by brazing. The intake pipe member extends through the tubular member to the intake port and is airtightly connected to the tubular member by welding. A plurality of grooves are formed in the outer peripheral surface of the tubular member or in the inner peripheral surface of the pipe insertion member over the entire circumference of the surface. The brazing material is received in the grooves.
