Connector for hermetic compressors

Abstract

The present invention relates to a connecting tube ( 2 ) for hermetic compressors, which is responsible for connecting the housing ( 1 ) of a hermetic compressor to the tube ( 3 )—which may be the process valve tube or evaporation, condensation system—which comprises at least two portions composed of materials that are different from each other, which are associated by means of a suitable joining process—preferably welding, soldering or mechanical fastening. In the preferred embodiment of the invention, the connecting tube ( 2 ) comprises a first portion ( 5 ) comprising a first material and a second portion ( 6 ) composed of a second material, wherein the second portion ( 6 ) of the connecting tube ( 2 ) can join the first portion of the connecting tube ( 5 ) and the system tube ( 3 ).

1 . Connector for hermetic compressors, of the type comprising a tube ( 2 ) for interconnection between a housing ( 1 ) of a compressor and an any system tube ( 3 ) such as, for example, of the evaporation, condensation system or process valve tube process CHARACTERIZED in that such connector comprises:
 a tube ( 2 ) as a single part containing at least two portion ( 5  and  6 ) composed of different materials, the portions ( 5 ,  6 ) being associated by means of a suitable joining process; and   means for allowing the connecting tube ( 2 ) to comprise at least two portions ( 5  and  6 ) consisting of different materials bound together by means of a suitable joining process.   
     
     
         2 . Connector according to  claim 1 , CHARACTERIZED in that said tube ( 2 ) in single part comprises:
 a first portion ( 5 ) composed of a first material and   one second portion ( 6 ) composed of a second material,   the first portion ( 5 ) of the connecting tube ( 2 ) being able to join the connecting tube ( 2 ) and the housing ( 1 ) of the compressor, and the second portion ( 6 ) of the connecting tube ( 2 ) being able to join the connecting tube ( 2 ) to the system tube ( 3 ).   
     
     
         3 . Connector according to  claims 1  and  2 , CHARACTERIZED in that the first portion ( 5 ) of the connecting tube ( 2 ) is made of a material pertaining to the group comprised of steel, aluminum and metals of appropriate characteristics. 
     
     
         4 . Connector according to  claims 1  and  2 , CHARACTERIZED in that the second portion ( 6 ) of the connecting tube ( 2 ) is made of copper. 
     
     
         5 . Connector according to any one of  claims 1  to  4 , CHARACTERIZED in that the first portion ( 5 ) of the connecting tube ( 2 ) is associated with the second portion ( 6 ) of the connecting tube ( 2 ) by means of a fastening process belonging the group comprised of brazing, welding or mechanical fastening.
