Suction Muffler

Abstract

Provide a suction muffler capable of enhancing the reliability of compressor, by preventing production of molten resin (slag) which solidifies in the suction muffler. Fit or put in contact with each other bonding portion ( 140 ) of a plurality of resin members ( 105 ), ( 120 ) formed in advance by injection molding, and bond bonding portion ( 140 ) with a resin belt formed with secondary injection molding. Because the bonding is made with the heat of the molten resin itself, it becomes possible to provide a suction muffler capable ( 101 ) of enhancing the reliability of compressor, by preventing production of slag due to pressing of bonding portion ( 140 ).

1 . A suction muffler formed by either fitting or putting in contact with each other the bonding portion of a plurality of resin members formed in advance by injection molding, and bonding the bonding portion with a resin belt formed with secondary injection molding.  
     
     
         2 . A suction muffler according to  claim 1 , wherein the shape of bonded face of the fitting portion is bent, at the cross section of the bonding portion.  
     
     
         3 . A suction muffler according to  claim 1 , wherein a plurality of projections or ribs are provided on the outer circumference of the bonding portion.  
     
     
         4 . A suction muffler according to  claim 1 , wherein a flange is formed in the state in contact with the contacts of the bonding portion.  
     
     
         5 . A suction muffler according to  claim 1 , wherein a tail pipe is formed separately inside the suction muffler, a through hole communicating with the tail pipe is provided at the bonding portion, and the resin member and the tail pipe are bonded to each other with the resin belt.
