Abstract

A condenser cartridge, in particular of an air-conditioning unit for vehicles, which can be inserted axially in an end of a cylindrical collector tube ( 11 ), comprises a cylindrical cap ( 12 ), suitable for making the seal inside the collector tube ( 11 ), and a casing ( 13 ) for a drying means that carries a filtering element ( 15 ) at one end, in which the cap ( 12 ) and the casing ( 13 ) are coupled through a ball-and-socket joint ( 16 ).

1 . Condenser cartridge, in particular of an air-conditioning unit for vehicles, which can be inserted axially in an end of a cylindrical collector tube ( 11 ), comprising a cylindrical cap ( 12 ), suitable for making the seal inside said collector tube ( 11 ), and a casing ( 13 ) for a drying means that carries a filtering element ( 15 ) at one end, characterized in that said cap ( 12 ) and said casing ( 13 ) are coupled through a ball-and-socket joint ( 16 ).  
   
   
       2 . Cartridge according to  claim 1 , characterised in that said ball-and-socket joint ( 16 ) comprises a first portion ( 17 ), or spherical element, made integrally at one end of said casing ( 13 ) and a second portion ( 18 ), or matching socket, made integrally on the inner surface of said cap ( 12 ).  
   
   
       3 . Cartridge according to  claim 1 , characterised in that said ball-and-socket joint ( 16 ) is made on said casing ( 13 ) close to said end carrying the filtering element ( 15 ).  
   
   
       4 . Cartridge according to  claim 1 , characterised in that said casing ( 13 ) comprises a rigid containment element integral with said filtering element ( 15 ) provided with a plurality of holes or openings ( 14 ).  
   
   
       5 . Cartridge according to  claim 4 , characterised in that a portion of said casing ( 13 ) provided with openings ( 14 ) is separated with respect to said filtering element ( 15 ) by a perimetric ring ( 23 ).  
   
   
       6 . Cartridge according to  claim 1 , characterised in that said casing ( 13 ) comprises a bag that is permeable to the cooling fluid connected to said filtering element ( 15 ).  
   
   
       7 . Cartridge according to  claim 6 , characterised in that said permeable bag is separated with respect to said filtering element ( 15 ) by a perimetric ring ( 23 ).  
   
   
       8 . Cartridge according to claims  5  or  7 , characterised in that said perimetric ring ( 23 ) is formed integrally on the outer wall of said casing ( 13 ).
