Abstract

A compressor which has a pipe coupling structure capable of fluid-tightly connecting a refrigerant pipe to a pipe coupling port, without needing any welding process to connect the pipe to the pipe coupling port, and a method of connecting the refrigerant pipe to the pipe coupling port of the compressor. The compressor includes a pipe to form a refrigerant path through which a refrigerant flows, a pipe coupling port connected to the pipe, and a hollow bushing having an inner surface to define a hole to receive an end of the pipe, and an outer surface to come into contact with the pipe coupling port, when the hollow bushing is thrust at an end thereof, at which the end of the refrigerant pipe is placed, so as to be compression-fitted into the pipe coupling port. The method includes inserting the hollow bushing into the pipe coupling port, inserting the end of the pipe into the hole of the hollow bushing, and thrusting the hollow bushing at the end of the bushing, at which the end of the refrigerant pipe is placed, so as to compression-fit the bushing into the pipe coupling port. The present invention simplifies a pipe connecting process, reduces the number of pipe coupling elements to improve productivity during the pipe connecting process, and accomplishes a firm pipe coupling structure and a desired sealing effect at a junction of the pipe and the port.
