Definitions

  • the present invention essentially relates to a device for connecting conduits for hot gases leaving, for example, an internal combustion engine.
  • connection thus produced can be carried out by cutting and welding beforehand the ends of the conduits, but the operation is delicate and implies that the conduits deviate near their junction in order to be able to have a weld bead between them.
  • the juxtaposed ends have excessive heating, because they have no contact with the ambient air, so that expansions can occur in the long term causing cracks and even ruptures of the conduits.
  • connection device which comprises the provisions set out in the preamble of claim 1.
  • This device as illustrated in FIG. 10, comprises in particular a flange with openings traversed by conduits which are connected to a nozzle by means of the flange.
  • the use of such a flange provides large spacings between the conduits themselves and between the conduits and the wall of the end piece, and these spacings provide significant bulk and a disturbed flow of gases at the connection.
  • the present invention aims to remedy all the above drawbacks by proposing a connection device which avoids excessive heating and any deterioration of the juxtaposed conduits, even after long use.
  • the subject of the invention is a device for connecting conduits for hot gases in which the ends of the conduits are juxtaposed and shaped so that the assembly thus formed can be fitted into the end of a pipe or the like.
  • an intermediate piece forming a spacer is interposed between the ends of the conduits and remains in contact with them, this intermediate piece forming a spacer being hollow and comprising on the one hand a bottom on the side of the end piece and on the other hand a through end located on the side opposite the endpiece, characterized in that said intermediate part has substantially the shape of a flattened tube with two substantially parallel walls which apply respectively to the flat parts opposite the conduits , or the shape of a star with at least three hollow branches, against and between which apply the ends of the conduits.
  • At least two pipes are provided which open into the aforementioned hollow intermediate piece in order to ensure a forced air flow therein, in which case the end of the hollow piece opposite to that situated on the side of the tip can be optionally closed.
  • the above-mentioned hollow intermediate piece is made of folded and welded sheet metal and is assembled by welding with the exhaust conduits, the ends of which are directly fitted and welded to the end piece.
  • the invention also relates to an internal combustion engine equipped with a connection device meeting one and / or the other of the above characteristics.
  • connection according to this invention is carried out between a plurality of conduits or tubes 1, connected on one side to an engine cylinder head by means of a fixing flange 2 and, from the on the other hand, to a pipe 3 which can be connected to a silencer (not shown) and comprising a nozzle 4.
  • endpiece 4 is fitted on the parallel and juxtaposed ends 1a of the exhaust conduits 1.
  • a hollow intermediate piece 5 forming a spacer is interposed between the juxtaposed and substantially parallel ends 1a of the conduits 1 and remains in contact over its entire extent with said ends, this spacer 5 comprising a bottom 6 on the side of the end piece 4, as seen in particular in FIGS. 2, 4, 7 and 8.
  • the hollow part or spacer 5 is closed at its end situated on the side of the pipe 3 fitted on the ends 1a conduits or tubes 1.
  • the hollow intermediate piece 5 has the shape of a flattened tube with two substantially parallel walls 6a which are applied respectively on the flat portions facing the ends 1a of two tubes 1.
  • the end forming the bottom 6 of the hollow piece or spacer 5 located on the side of the end piece 4 of the pipe 3 is profiled and welded, while the opposite end of this piece opens out at 6b on the side opposite the pipe 3, it that is to say in the interval 7 between the two conduits 1.
  • the hollow part or spacer 5 has, in cross section, the shape of a star with three branches 8 against which the ends 1a of three conduits are applied.
  • the three hollow branches of the part 5 are closed at their end situated on the side of the end piece 4 of the pipe 3.
  • the hollow intermediate part 5 still has substantially, in cross section, the shape of a star with three branches. But here the ends 1a of the conduits 1 have a circular section, so that said ends bear on concave faces 9 forming the three hollow branches of the part 5, whereas, in the case of FIG. 5, the ends 1a of the conduits 1 have flat parts 10 applying to the flat branches of the star constituting the hollow part 5.
  • the hollow intermediate piece 5 has in cross section the shape of a star with four branches, the end 6 of which is located on the side of the end piece 4 of the pipe 3 is closed, as can be seen in FIGS. 7 and 8.
  • conduits 1 are applied against the four branches of the hollow spacer 5.
  • the end 6b can be closed by welding, in which case the pipes 11 and 12 are connected to a system (not shown) causing an air flow, this system using for example the aforementioned dynamic effect or a pulser associated with the motor.
  • the assembly is carried out by fitting and welding the endpiece or nozzle 4 on the ends 1a of the conduits or tubes 1 previously welded on the hollow spacer 5.
  • the various welds can easily performed thanks to good accessibility to the areas to receive a weld bead.
  • connection device with hollow spacer which allows good heat exchange between the respective ends 1a conduits 1 and the ambient air thanks to the recess opening into the interior of this spacer, and possibly, thanks to the flow of air forced into this recess. Consequently, such a connection device does not require the use of expensive metals since it does not undergo excessive heating.
  • the hollow spacer piece on which the ends 1a of the conduits or tubes 1 are applied will advantageously allow free internal radial deformations, materialized by the arrows F, of these ends, which expansions result of course from the temperature of the hot gases. evacuated from the engine by the conduits 1. This means that any cracking or deterioration of the conduits 1 and of their ends 1a will be avoided.
  • Conduits such as 11 and 12 opening into the hollow spacer 5 can be provided on a spacer comprising an end 6b which can be open or not, and that the spacer 5 has the form of a flattened tube or the form d 'a three-pointed star, four or more branches.
