- the swirl generator has an annular, radial outer area, which may also be the same as mentioned Fastening flange forms, with internal guide vanes and the guide vanes are rigidly arranged, according to one particular preferred embodiment, the guide vanes adjustable and / or are deformable so that an adjustment according to the Mass throughput can take place.
- An embodiment of the guide vanes of the Swirl generator viewed from an elastically deformable plastic.
- the swirl generator is according to a preferred embodiment of axially flows through a flow medium, the extend Guide vanes of the swirl generator starting from a fixed leading edge, which is connected to the annular, radially outer region, in Flow direction and have a curvature in the radial direction on, so that a flow swirl can be generated.
- the guide vanes of the swirl generator expediently overlap in areas with little or no flow, areas totaling 20-30%, in particular of approx. 25% of the flow area. "Flown area” the swirl generator is present in the sense of an axial projection understand.
- the Swirl generator four guide vanes, which in little or no flow State each one over an angle of 35-45 °, in particular of approx. 40 °, the circular segment-like area of the flow Cover area.
- Embodiment of the invention opposes the guide vanes of the swirl generator their radial curvature deformed so that a lower flow swirl is produced.
- a preferred embodiment of the swirl generator with four According to guide vanes cover the upper and the maximum Operating range of the compressor or the pump each one over an angle of 1 - 11 °, in particular of about 6 °, Area of the flow area in the shape of a segment of a circle.
- a radial compressor 1 is not shown here Exhaust gas turbocharger of an internal combustion engine with an intake side Swirl generating device 2 shown.
- the compressor includes an in a housing 3 arranged impeller 5 with impeller blades, which is driven by means of an exhaust gas turbine via a shaft. Doing so according to arrow direction A charge air via a charge air suction line 6 sucked in and via a diffuser channel 17 and a spiral channel 4 into a Boost air pressure line promoted; if necessary, the charge air recirculated exhaust gas mixed.
- the swirl generator 7 has a cylindrical, tubular section-shaped base body 11 with internal guide vanes 18 on and is inserted into the charge air line 6, so that the outside of the base body 11 bears against the inside of the charge air line 6.
- this includes a flange 12, the charge air line side Surface rests on a shoulder 13 of the charge air line 6, whereas the surface of the flange 12 on the compressor side with the end face of a seal 8 communicates.
- the diameter of the flange 12 corresponds approximately the inner diameter of the widened end 15 of the charge air line 6, so that there is also a definition in the radial direction.
- the compressor housing 3 is in the form of a pipe socket on the charge air inlet side formed, the end portion 10 of the socket 16 on the outside has reduced diameter on which the rubber elastic Seal 8 is pushed on.
- the seal 8 is in the direction of Flange 12 of the swirl generator 7 over the end 14 of the socket 16 over, so that the swirl generator 7 is decoupled from the compressor housing 3.
- the seal 8 has circumferential fins 9, which are allow easy pushing on the charge air line 6, but a prevent unintentional loosening of the connection; is also on the Flange 12 is held with a certain preload in the axial direction.
- the swirl generator 7 comprises four to nine blades 18, the outlet angle corresponding to the Charge air mass flow can be selected between 15 ° and 75 °.
- the blades 18 of the swirl generator 7 depending on Mass throughput adjustable or deformable expediently one Adjustment or deformation is caused by the gas force itself.
- the swirl generator 7 consists of a plastic such as, for example glass fiber reinforced polyamide, where appropriate - especially if backflow of hot charge air from the compressor is not effective can be prevented - a metal version is preferred. Due to the high temperatures that occur during charge air compression the compressor housing 3 is made of cast aluminum; the Charge air intake pipe is made of glass fiber reinforced polyamide.
- the swirl generator 7 with blades 18 is without Center bar is shown, however, according to another embodiment a design with a central central web is also expedient considered.
- FIG. 2 shows a four-bladed swirl generator in different views.
- the swirl generator 200 is one-piece in an injection molding process from a relative soft, thermoplastic with a hardness of approx. 45 Shore D made so that the wings 202 have the required flexibility.
- the areas that require greater stability - like the ring-shaped, radially outer region 204, the leading edges 206 of the wing 202 and the Central area 208 - are constructive, in particular by means of saponification ribs or material reinforcements designed accordingly.
- the wings 202 are on their radially inner side in the central region 208 their half length is connected axially straight to each other, so that each a free, particularly deformable wing end 216 remains. On the outside, can the wing curvature from the wing end 216 to the area of Continue leading edge 202, since wing 202 is not axially straight here are set.
- the leading edges 206 and those in FIG Flow direction a extending wing 202 recognizable.
- the swirl generator in the area between the suction line and the pump or Compressor housing (see FIG. 1) by means of the annular, radially outer one Area 204 set so that this area 204 in the axial direction outstanding areas, such as leading edges 206 and wings 202, for A reduced intake in the intake manifold or in the intake manifold Have diameter.
- the central region 208 is conical on the inflow side, which Wing edges 218 are smaller in the direction of flow a Diameter withdrawn, the ends are rounded.
- the annular, radially outer region 204 of the swirl generator 200 lip 220 on the outside.
- the lip has a slightly larger one Diameter than the clear diameter of the insertion area, see above that the swirl generator 200 only with the leading edges 206 forward can be inserted.
- the curvature of the guide vanes 202 causes a swirl to be applied to the flowing in direction a.
- the swirl generation depends on the curvature of the guide vanes 202
- the Guide vane curvature dependent on mass flow.
