Definitions

  • the invention relates to a flange for supplying coolant to a component that is to be cooled, and to a component equipped with such a flange. It will find notable applications as a coolant supplying flange of a combustion engine air circuit valve.
  • a “combustion engine air circuit” means the circuit between the intake inlet and the exhaust outlet of the combustion engine.
  • the valve may be positioned in the intake circuit, in the exhaust circuit, or in a recirculation loop through which exhaust gases reinjected into the intake side pass (this being more commonly known as an EGR loop).
  • an internal combustion engine exhaust gas recirculation system makes it possible to reduce the amount of nitrogen oxides present in the exhaust gases.
  • a recirculation system comprises a bypass duct on the exhaust gas pipe, this duct being equipped with a flow regulating valve, referred to as an EGR valve, that allows the desired amount of exhaust gas to be returned to the intake side of the engine.
  • Such a valve therefore has passing through it gases which, although sometimes cooled before passing through the valve, are at very high temperatures. It is therefore appropriate to cool said valve and to do so it is known practice to use a coolant passing through a network of ducts that pass through the valve.
  • inlet and/or outlet flanges In order to circulate the liquid through the valve use is made of inlet and/or outlet flanges. These are centered on the ducts of the valve with which they communicate via a barrel that makes it easier to fit and position the flanges on the valve.
  • the invention proposes to address these problems by improving the cooling of the valve near the flange without losing the centering functionality of the flanges of the prior art.
  • the invention thus relates to a flange for supplying coolant to a component that is to be cooled, notably a valve, 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.
  • said barrel has one or more passages allowing the fluid a transverse circulation between said circulation duct of the component and said circulation canal of said flange.
  • the invention also relates to a component that is to be cooled, notably a combustion engine air circuit valve such as an exhaust gas recirculation valve or EGR valve, comprising a coolant circulation duct and a flange as described hereinabove for the passage of said fluid to and/or from said duct.
  • a combustion engine air circuit valve such as an exhaust gas recirculation valve or EGR valve
  • the invention relates to a combustion engine cooling circuit valve comprising a coolant circulation duct and a flange as described hereinabove for the passage of said fluid to and/or from said duct.
  • Said duct advantageously widens in line with said barrel to create a jacket for the circulation of said coolant between said barrel and a wall of said duct.
  • Said wall of the duct may comprise an angular succession of ribs and grooves to limit the area of contact between the barrel and the component.
  • Said ribs and/or grooves are, for example, oriented along the longitudinal extension of the barrel.
  • only the surface of the grooves is machined.
  • FIG. 1 a partial perspective view of one embodiment of a flange according to the invention
  • FIG. 2 a view in longitudinal section of the flange of FIG. 1 mounted in a cooling duct of an EGR valve;
  • FIG. 3 a perspective view of the duct of the valve of FIG. 2 , illustrated without the flange.
  • the invention relates to a coolant supply flange 1 for a component that is to be cooled, notably a motor vehicle component.
  • a coolant supply flange 1 for a component that is to be cooled, notably a motor vehicle component.
  • This may in particular be an exhaust gas recirculation valve.
  • Such a valve is partially illustrated in FIG. 2 .
  • Said component that is to be cooled is made for example from a cast structure or body 2 , notably made of aluminum and/or aluminum alloy.
  • said body 2 comprises a gas circulation duct, not visible.
  • a valve shut-off member such as a valve shutter or flap, is configured to shut off said gas circulation duct to a greater or lesser extent so as to allow the rate of flow of such gases through the valve to be regulated.
  • Said valve may comprise dynamic members, such as a gear set with cogged wheels, for actuating said shut-off member or members from a valve drive motor. It may further comprise instrumentation, notably a position sensor, for monitoring said dynamic and/or shut-off members.
  • said component comprises a network for the passage of a coolant, notably water to which an antifreeze, particularly glycol, has been added, this coolant coming from a vehicle cooling circuit.
  • Said component comprises at least one circulation duct 4 for said coolant, through which duct said coolant enters and/or leaves said component.
  • Said flange 1 comprises a centering barrel 3 for centering it in said coolant circulation duct 4 in said component.
  • Said barrel 3 extends in an axial direction D. It defines a circulation canal 5 for said coolant which extends in said axial direction D.
  • said barrel 3 is, for example, cylindrical, notably of circular cross section.
  • Said circulation canal 5 may likewise be of circular section so that said barrel 3 is formed of an annular wall 17 .
  • Said canal 5 opens in said axial direction D, for example at a distal end 11 of the barrel 3 .
  • Said barrel 3 encourages insertion of the flange 1 into the component that is to be cooled and correct positioning with respect to said component.
  • said flange 1 here comprises a mounting plate 7 for fixing it to said component.
  • Said mounting plate 7 is, for example, perpendicular to said barrel 3 . It may comprise orifices 9 for the passage of fixing screws, not illustrated.
  • said component that is to be cooled comprises, for example, bores 6 for fixing said flange 1 to said component that is to be cooled using said screws.
  • said component that is to be cooled may comprise a seal 8 to seal between said coolant circulation duct 4 and the outside of the component that is to be cooled.
  • Said seal 8 is situated between said flange 1 and said component that is to be cooled and it will be appreciated that sealing is notably dependent on correct positioning of said flange 1 with respect to said component.
  • Said flange 1 may comprise, at the base of the barrel 3 , a shoulder 15 configured to collaborate with the seal 8 .
  • Said flange 1 may furthermore of course comprise one or more connecting orifices, not illustrated, connecting to the cooling circuit supplying said component that is to be cooled.
  • said barrel 3 has one or more passages 13 allowing transverse circulation of the fluid between said circulation duct 4 of the component and said circulation canal 5 of said flange 1 .
  • Transverse here means a direction that is inclined with respect to the longitudinal direction of the barrel 3 .
  • Said coolant is thus directed not only toward the distal end 11 of the barrel 3 but also toward a wall 10 of the circulation duct 4 that lies laterally facing said barrel 3 .
  • Said wall 10 may consequently likewise be cooled. That then avoids the creation of hot spots that experience strong thermal expansion phenomena, stressing the material of the body 2 near the flange 1 and risking impediment of the sealing afforded by said seal 8 and impediment of the good mechanical connection between the flange 1 and the component in the region of said bores 6 .
  • Said passage or passages 13 are situated, for example, between said shoulder 15 and said distal end 11 of the barrel 3 .
  • Said passage or passages 13 here are slits extending in the direction of longitudinal extension of the barrel, said slits 13 being open axially to the distal end 11 of the barrel 3 .
  • Said slit or slits 13 are three in number here, evenly spaced apart.
  • Said slits 13 are separated by branches 19 of said barrel 3 that extend angularly between two adjacent slits 13 of said barrel. In other words, said slits 13 are formed by interruptions in the annular wall 17 of said barrel 3 .
  • Said annular wall 17 here is defined by said branches 19 which are intended to project from the shoulder 15 .
  • the distal end 11 of the barrel 3 is defined by a distal end of said branches 19 .
  • Said barrel 3 is advantageously provided with reinforcing ribs 21 , arranged in said circulation canal 5 of the barrel 3 between the branches 19 .
  • Said reinforcing ribs 21 are oriented, for example, in the direction of longitudinal extension D of said barrel 3 , particularly radially. They are three in number here and arranged in a star shape from the longitudinal direction of said canal 5 . In that way they divide said canal 5 into three sub-canals for the passage of the coolant.
  • said duct 4 for example widens in line with said barrel 3 to create a jacket 12 for the circulation of said coolant between said barrel 3 and the wall 10 of said duct 4 .
  • said wall 10 of the duct 4 comprises, particularly in the region of said jacket 12 , an angular succession of ribs 14 and grooves 16 to limit the area of contact between the barrel 3 and the component that is to be cooled.
  • Said ribs 14 and/or grooves 16 at one of their longitudinal ends have a shoulder 20 that faces the shoulder 15 of the flange 1 , said seal 8 being placed between said shoulders 15 , 20 .
  • Said ribs 14 and/or grooves 16 are oriented, for example, in the longitudinal direction of the barrel 3 . They may have a substantially trapezoidal shape, the long base of the ribs 14 being situated at one and the same axial end of said jacket 12 as the short base of the grooves 16 , and vice versa at the opposite end.
  • said component may comprise a part 18 projecting from the rest of its body 2 in the region of which projecting part a mouth of said circulation duct 4 and/or said bores 6 are formed.
