Estimating the term…
A compression element located inside an enclosed compressor is disclosed for receiving a connection pipe from outside the compressor. The compressor has an opening one in one of its walls. The compression element has a bore running through it. An inlet end of the compression element is joined to the wall of the compressor at the opening. The inlet end of said bore is tapered in the form of a curved shape that spreads smoothly toward the opening. A guide pipe has one of its ends installed into the opening from outside the compressor. A connection pipe having a cooper plated exterior surface is inserted through the guide pipe, press-fitted into the inlet end of the compression element and joined to the compression element. The connection pipe has another end connected to a suction pipe for circulating a refrigerant within the compressor via the compression element.
An enclosed type compressor comprising:
A method of manufacturing an enclosed type compressor, which comprises an enclosed container having an opening in a wall thereof, a compression element located in said enclosed container, which compression element has a bore having an inlet end in communication with said opening, and a connection pipe having one end for insertion into said bore inlet end in a press-fitted manner and having another end for connection to a suction pipe for circulating a refrigerant within said enclosed container via said compression element,
