Compressor, and method of manufacturing same including a press-fit inlet tube

A method of manufacturing a compressor in which a compression element having a cylinder with a refrigerant suction opening formed therethrough is built-in to a casing which has a connecting opening at a position corresponding to a position of said refrigerant suction opening, a connecting cylinder is formed integrally with said casing such that said connecting opening outwardly of said casing, and a refrigerant pipe is connected to said compression element through an inlet tube press-fitted into said refrigerant suction opening and said connecting cylinder, said method comprising the steps of:

• setting said compression element in said casing with said refrigerant suction opening held so as to confront said connecting cylinder such that said compression element is prevented from being displaced vertically;
• press-fitting said inlet tube into said refrigerant suction opening and said connecting cylinder such that said compression element is prevented from being displaced with respect to said casing and such that said inlet tube closely contacts said cylinder of the compression element having said refrigerant sucking hole formed therethrough and said connecting cylinder;
• fixing said casing and said compression element by spot welding;
• welding fixedly said inlet tube to said connecting cylinder;
• and
• connecting said inlet tube to said refrigerant pipe such that said inlet tube has a portion closely contacting said refrigerant pipe.
