Sealing ring to be applied to connection holes of cells of an accumulator

Abstract

The finding realises a sealing ring ( 1, 100, 101 ) to be applied to frusto-conical connection holes ( 5 ) of the cells (L) of an accumulator (A) which comprises a plate ( 2, 2 a ) equipped with a through hole ( 3, 31 ) axially to which is arranged the base ( 7 ) of a sheath ( 4, 4 a, 4 b ) suitable for coupling in the connection hole ( 5 ). A portion of the cross-section of the sheath ( 4, 4 a, 4 b ) has a diameter ( 8 ) greater than the diameter ( 9 ) of the base ( 7 ) of the sheath ( 4, 4 a, 4 b ).

1 . A sealing ring to be applied to frusto-conical connection holes of the cells of an accumulator comprising a plate equipped with a through hole axially to which is arranged the base of a sheath suitable for coupling in said connection hole wherein at least a portion of the cross-section of said sheath has a diameter greater than the diameter of the base of said sheath.  
   
   
       2 . A sealing ring according to  claim 1)  wherein at least a portion of the profile of the outer surface of said sheath is substantially frustoconical.  
   
   
       3 . A sealing ring according to  claim 2)  wherein the taper of said at least a part diverges moving away from said plate).  
   
   
       4 . A sealing ring according to  claim 1  wherein at least a portion of the profile of the inner surface of said sheath is frusto-conical.  
   
   
       5 . A seaing ring according to wherein the angle defined by said outer surface and said plate is less than 90 degrees.  
   
   
       6 . A sealing ring according to  claim 1  wherein the profile of the outer surface of said sheath substantially matches the profile of said hole.  
   
   
       7 . A sealing ring according to  claim 1  wherein said plate is substantially circular.  
   
   
       8 . A sealing ring according to  claim 1  wherein said sheath has a length equal to the thickness of the divider walls of said accumulator.  
   
   
       9 . A sealing ring according to  claim 1  wherein said sheath has a length less than the thickness of the divider walls of said accumulator.
