Coolant-supplying flange for a component to be cooled and component provided with such a flange

Abstract

The invention relates to a coolant-supplying flange for a component to be cooled, especially an exhaust gas recirculation valve, said flange comprising a centring drum ( 3 ) in a duct ( 4 ) for the circulation of said coolant in said component, said drum ( 3 ) extending in an axial direction, said drum ( 3 ) being crossed by a channel ( 6 ) for the circulation of said coolant, extending in said axial direction, said drum ( 3 ) having at least one passage ( 13 ) allowing a transverse circulation of the fluid between said circulation duct ( 4 ) of the component and said circulation channel ( 6 ) of said flange.

1 . A flange for supplying coolant to an exhaust gas recirculation valve to be cooled, said flange comprising:
 a centering barrel for centering in a duct for the circulation of said coolant in said component,
 said barrel extending in an axial direction, 
 said barrel having passing through it a canal for the circulation of said coolant extending in said axial direction, and 
 said barrel having one or more passages allowing the fluid a transverse circulation between said circulation duct of the component and said circulation canal of said flange. 
   
     
     
         2 . The flange as claimed in  claim 1 , further comprising, at the base of the barrel, a shoulder configured to collaborate with a seal intended to afford sealing between said circulation duct of the component and the outside of the component. 
     
     
         3 . The flange as claimed in  claim 2 , said passage or passages being situated between said shoulder and a distal end of the barrel. 
     
     
         4 . The flange as claimed in  claim 1 , said barrel being cylindrical. 
     
     
         5 . The flange as claimed in  claim 1 , said barrel being of circular cross section. 
     
     
         6 . The flange as claimed in  claim 1 , said passage or passages being slits extending in the direction of longitudinal extension of the barrel. 
     
     
         7 . The flange as claimed in  claim 1 , said passage or passages being open axially at the distal end of the barrel. 
     
     
         8 . The flange as claimed in  claim 1 , said passage or passages being three in number. 
     
     
         9 . The flange as claimed in  claim 1 , said barrel further comprising an annular wall extending around the axial direction in which the passages are made, two consecutive passages between them defining a branch. 
     
     
         10 . The flange as claimed in  claim 9 , said barrel being provided with reinforcing ribs, each rib extending between the center of the canal and a branch. 
     
     
         11 . The flange as claimed in  claim 10 , said reinforcing ribs being oriented in the direction of longitudinal extension of said barrel. 
     
     
         12 . A component that is to be cooled comprising:
 a coolant circulation duct; and a flange as claimed in  claim 1  for the passage of said fluid to and/or from said duct.   
     
     
         13 . The component as claimed in  claim 12 , said duct being widened in line with said barrel to create a jacket for the circulation of said coolant between said barrel and a wall of said duct. 
     
     
         14 . The component as claimed in  claim 13 , said wall of the duct comprising an angular succession of ribs and grooves to limit the area of contact between the barrel and the component. 
     
     
         15 . A valve for a combustion engine air circuit or for a combustion engine cooling circuit, comprising a component as claimed in  claim 12 .
