Working Fluid Unit Containing A Temperature-Sensitive Vehicle Working Fluid

Abstract

A working fluid unit, comprising a container having a temperature-sensitive vehicle working fluid contained therein, in particular for exhaust gas after-treatment, a container mantle which is open at least on one side and in which the vehicle working fluid is introduced and the opening of which is closed by a container lid, wherein the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding, or magnetic pulse crimping, wherein the connecting seam is spaced a distance from the vehicle working fluid that is present.

1 . An operating fluid unit, comprising a container with a temperature-sensitive vehicle operating fluid contained therein, a container mantle open at least on one side, into which the vehicle operating fluid is introduced, and the opening of which is closed by means of a container lid, wherein the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding or magnetic pulse crimping, thereby forming a connecting seam. 
     
     
         2 . The operating fluid unit according to  claim 1 , wherein the connecting seam is spaced a distance from the contained vehicle operating fluid. 
     
     
         3 . The operating fluid unit according to  claim 1 , wherein the container lid is connected to the container mantle by magnetic pulse crimping with the interposition of a gasket ring into a groove of the container mantle and/or container lid. 
     
     
         4 . The operating fluid unit according to  claim 1 , wherein the connecting seam is disposed with a distance from the interior of the container at an edge of the container lid facing outwards from the container opening. 
     
     
         5 . The operating fluid unit according to  claim 4 , wherein the edge is profiled on the external peripheral side, preferably tapered. 
     
     
         6 . The operating fluid unit according to  claim 4 , wherein the container lid is manufactured from sheet metal and the edge is manufactured by reshaping or beading. 
     
     
         7 . The operating fluid unit according to  claim 4 , wherein the container lid is manufactured from cast synthetic material or cast metal, and the edge is manufactured by moulding. 
     
     
         8 . A method for manufacturing a container containing a temperature-sensitive vehicle operating fluid, comprising the steps of: providing a container mantle open on at least one side; introducing the vehicle operating fluid into the container mantle; and, closing the container mantle opening by means of a container lid, wherein the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding or magnetic pulse crimping, thereby forming a connecting seam. 
     
     
         9 . The method according to  claim 8 , wherein the connecting seam is spaced a distance from the vehicle operating fluid. 
     
     
         10 . The method according to  claim 8 , wherein the container lid is connected to the container mantle by magnetic pulse crimping with the interposition of a gasket ring into a groove of the container mantle and/or container lid. 
     
     
         11 . The method according to  claim 8 , wherein the connecting seam is disposed at an edge of the container lid facing outwards away from the container opening. 
     
     
         12 . The method according to  claim 11 , wherein the edge is embodied in a profiled manner on the external peripheral side, preferably in a tapered manner. 
     
     
         13 . The method according to  claim 11 , wherein the container lid is manufactured from sheet metal, and the edge is manufactured by reshaping or beading. 
     
     
         14 . The method according to  claim 11 , wherein the container lid is manufactured from cast synthetic material or cast metal, and the edge is manufactured by moulding or milling.
