Definitions
- Supercharging device of an internal combustion engine comprising a pulsation damping chamber
- the present invention relates to a supercharging device of an internal combustion engine comprising a damping chamber pulsations generated at the output of the compressor.
- a first damping chamber is located midway on the air intake duct which connects the output of the compressor to the intake manifold of the engine.
- one or two other damping chambers are arranged on ducts connected to the section of the intake duct between the compressor and the first damping chamber.
- FIGS. 1 and 2 attached illustrate the state of the art closest to the invention.
- the reference 1 designates a turbocharger comprising a turbine 2 driven by the gases flowing in the exhaust duct 3 of the heat engine 4.
- the turbine 2 drives the wheel 5 of the compressor 6 which sends the compressed air into the intake duct 7 connected to the intake manifold 8 of the engine 4.
- the intake duct 7 comprises on its path a chamber 9 whose structure is detailed in FIG.
- the end 11 of the duct 7 is fixed around the nozzle 10 by latching means comprising a retaining clip 19.
- the damping chamber 9 comprises a cylindrical outer wall 12 which surrounds a cylindrical inner wall 13 whose diameter is substantially equal to that of the intake duct 7. Between the cylindrical walls 12 and 13 are created two annular spaces 14 and 15 separated from each other by a partition 16. Each space 14, 15 opens into the interior of the duct 7 by an annular slot 17, 18.
- the entire damping chamber is made by several elements welded together.
- FIG. 2 shows in detail the snap-fitting arrangement of the end 11 of the intake duct 7 around the outlet endpiece 10 of the compressor 6.
- the end 11 of the duct 7 has a flared shape towards the compressor comprising an annular shoulder 24 which is supported on the end of a sleeve 23 which surrounds the outlet nozzle 10 of the compressor.
- the flared end 11 of the duct 7 is fixed to the sleeve 23 by snap-fastening by means of a retaining clip 19. Between the end 11 and the sleeve 23, seals 20, 21 are inserted.
- the object of the present invention is to make improvements to the device known above by simplifying its construction while improving the efficiency of the damping chamber.
- the supercharging device of an internal combustion engine comprising a turbocharger whose turbine is driven by the engine exhaust gas and whose compressor driven by this turbine compresses the intake air of the engine, the air intake duct connecting the outlet of the compressor to the air intake manifold to the engine, comprising a damping chamber of the pulsations generated at the outlet of the compressor, is characterized in that said damping chamber is connected directly to the compressor output.
- said damping chamber partially surrounds a tubular nozzle connected to the outlet of the compressor.
- said damping chamber comprises an outer cylindrical wall and an inner wall between which two contiguous annular spaces are formed and the inner wall of one of the annular spaces surrounds said outlet end of the compressor.
- This inner wall thus forms the end of the intake duct which fits around the outlet end of the compressor, which simplifies the construction of the device.
- said damping chamber comprises, in a radial plane located substantially in the middle, a partition having a circular central opening whose diameter is substantially equal to the diameter of the tubular endpiece connected to the compressor output;
- said central opening is extended in a direction opposite to said mouthpiece by a tubular duct defining, with the outer wall of said damping chamber, an annular space which opens towards the air intake duct through an annular opening formed between the free end of said tubular duct and the connection zone of said chamber with the air intake duct;
- said damping chamber has another annular space in a zone extending between said annular partition and the zone of connection of said damping chamber with the outlet of the compressor;
- said other annular space opens radially towards the axis of the outlet end of the compressor by a circular slot adjacent to the edge of said circular opening;
- the compressor outlet nozzle is annularly surrounded by a sleeve fixed around the outlet of the compressor, the end of the outer wall of the chamber opposite the air intake duct being fixed by snapping around said sleeve; said sleeve is surrounded by a tubular element, one end of which has a rim bearing on the output edge of said outlet nozzle and the other end of which is inserted between said outlet nozzle and the adjacent end of the outer wall of the chamber and is fixed to said sleeve by the means for snap-fitting the end of the outer wall of the chamber to said sleeve.
- FIG. 1 is a diagrammatic view in longitudinal section of a supercharging device comprising a known damping chamber
- FIG. 2 is a partial view of the device according to FIG. 1, showing the detailed structure of the damping chamber and the connection of the intake duct at the outlet of the compressor;
- FIG. 3 is a view similar to FIG. 1 illustrating the device according to the invention
- FIG. 4 is a view similar to Figure 2, showing the damping chamber of the device according to the invention and its direct connection to the output of the compressor.
- the supercharging device of an internal combustion engine 4 comprises a turbocharger 1 whose turbine 2 is driven by the exhaust gases 3 of the engine 4 and whose wheel 5 of the compressor 6 driven by this turbine 2 compresses the intake air of the engine.
- the air intake duct 7 connecting the outlet 10 of the compressor 6 to the air intake manifold 8 to the engine 4 comprises a damping chamber 9a of the pulsations generated at the outlet of the compressor 6.
- this damping chamber 9a is connected directly to the outlet 10 of the compressor 6.
- the damping chamber 9a partially surrounds the tubular nozzle 10 connected to the outlet of the compressor 6.
- the damping chamber 9a comprises a outer cylindrical wall 12a and an inner wall 13a, 13b between which are formed two contiguous annular spaces 14a, 15a.
- the damping chamber 9a comprises, in a radial plane located substantially in the middle, a partition 16a having a circular central opening 20a whose diameter is substantially equal to the diameter of the tubular nozzle 10 connected to the outlet of the compressor.
- This central opening 20a is extended in a direction opposite to the tip 10 by a tubular conduit 13b defining, with the outer wall 12a of the damping chamber 9a, an annular space 15a.
- This annular space 15a opens towards the air intake duct 7 via an annular opening 18a formed between the free end of the tubular duct 13b and the zone 21 for connecting the chamber 9a with the air intake duct 7 .
- Figure 4 shows that the tubular conduit 13b has a flared shape in the opposite direction to its central inlet opening 20a. Moreover, the damping chamber 9a has an annular space
- the annular space 14a opens radially towards the axis of the outlet nozzle 10 of the compressor by a circular slot 17a adjacent to the edge of the circular opening 20a of the partition 16a.
- Figure 4 shows on the other hand that the outlet nozzle 10 of the compressor is surrounded annularly by a sleeve 23a fixed around the nozzle of the outlet 10 of the compressor.
- end 22 of the outer wall 12a of the chamber 9a opposite the air intake duct 7 is fixed by snapping around the sleeve 23a.
- the sleeve 23a is surrounded by a tubular element which is constituted by the inner wall 13a of the inner space 14a of the chamber 9a.
- this wall 13a has a flange 24a resting on the output edge of the outlet tip 10.
- the other end of this wall 13a is inserted between the sleeve 23a and the adjacent end 22 of the outer wall 12a of the chamber 9a and is fixed to the sleeve 23a by the means comprising a clip 19a for snap-fitting the end of the outer wall 12a of the chamber 9a to said sleeve 23a.
- several seals are inserted between the wall 13a defining the space 14a and the sleeve 23a.
- the inner wall 13a thus has a dual function, since it replaces the two walls 13 and 11 of the device shown in FIGS. 1 and 2.
- the other inner wall 13b of the chamber 9a can be made in one piece (as shown in Figure 4) with the partition 16a, which makes it possible to save a weld.
- damping chamber 9a is located closer to the compressor, there is an improvement in its efficiency and a reduction of the space between the compressor and the intake manifold of the engine.
