<P>PROBLEM TO BE SOLVED: To provide a suction muffler for a compressor, which is configured to prevent the suction of oil from the suction muffler. <P>SOLUTION: A suction muffler 7 is provided within a compressor casing at a position on a refrigerant path upstream side of an inlet of a compression chamber and is disposed at a position at which the suction muffler receives oil sprayed from the upper part of the inside of the casing. The suction muffler 7 comprises an upper lid member 71 which is open at the bottom and a lower lid member 72 which is open at the top and which has a bottom wall having connected thereto both a refrigerant introduction pipe 8 and a refrigerant delivery pipe 72d. The upper lid member 71 and the lower lid member 72 are fitted and affixed to each other in such a manner that the inner surface of the sidewall of the upper lid member 71 is in close contact with the outer surface of the sidewall of the lower lid member 72. A protrusion section 72f surrounding the connection section between the refrigerant introduction pipe 8 and the refrigerant delivery pipe 72d is formed by causing the lower end of the sidewall of the upper lid member 71 to protrude further downward than the lower surface of the bottom wall of the lower lid member 72. <P>COPYRIGHT: (C)2013,JPO&INPIT |
