The spacer then ensures that regardless of the position of the control lever always a safe and good power transmission is ensured by the collar on the shovel shaft, and that self-locking of the Diaphragm according to the invention is avoided with certainty.
- Is in the support ring a connectable with a coolant source cooling channel formed, which is guided over the housing passages of the blade shafts in the flow channel, so Be lifetime and reliability of the diffuser according to the invention additionally elevated. At the same time thereby the escape of hot and aggressive exhaust gas from the Flow channel can be avoided with great certainty.
- FIG. 1 is from an exhaust gas turbocharger, only the turbine part with an exhaust gas turbine shown.
- Exhaust gas turbine has a rotatable about an axis 1 rotor 2 with a turbine runner and attached rotor blades 3 and a turbine housing 4 and a nozzle 5 with an axially symmetrical to the turbine axis 1 arranged ring of adjustable Guide vanes 6 and with a pivoting device 7.
- the vanes 6 can each through Turning about a guided in the radial direction axis 8 in any angular positions between two end positions are pivoted.
- the rotor 2 is in gas-tight manner from the turbine housing 4 to a not shown Led bearing point and carries at its left in Fig. 1 end one of the figure 1 no longer visible compressor wheel.
- the turbine housing 4 contains a gas inlet housing 9 with an axisymmetric arranged inlet opening 10 and a gas outlet housing 12 with a radial aligned outlet opening 13. Between inlet opening 10 and outlet opening 13th extends a limited by the turbine housing 4 flow channel 14.
- Inlet opening 10 is symbolized by arrows hot exhaust gas 15 from a not shown exhaust gas source, in particular an internal combustion engine supplied.
- This hot Exhaust gas 15 is first in a direction aligned in the direction of the turbine axis 1 section the flow channel 14 out. In this section, the exhaust gas 15 via the Guides 6 and the blades 3 out. Downstream of the blades 3 occurs that Exhaust gas 15 in a limited by the gas outlet housing 12 section of the Flow channel 14 in which it led away from the axis 1 to the outside and over Finally, the outlet opening 13 is removed from the turbine housing 4.
- the nozzle 5 is at a between the gas inlet 9 and the gas outlet housing 12 by means of screws clamped support ring 16 is held. Between the two housings 9 and 12 is also a clamped by the support ring 16 thermally decoupled relief ring 17, which the Flow channel 14 in the region of the vanes 6 radially outwardly limited and thereby shields the support ring 16 against the direct effect of the hot exhaust gases and thus thermally relieved.
- An attached to each of the vanes 6 blade shank 18 is through acting as a housing wall rings 17 and 16 radially outwardly of the Flow channel 14 out.
- the blade shank 18 is with its outwardly guided part rotatably supported about the pivot axis 8.
- the rotary motion is initiated by a arranged outside the flow channel 14 and rotatable about the turbine axis 1 Adjusting ring 19 and a torque from the adjusting ring 19 on the blade shank 18 each Guide vane transmitting control lever 20.
- the blade shank 18 is attached to the guide blade 6 in such a way that the Swivel axis 8 between the front edge 21 and one of the blade pressure points connecting line 22 of the vane runs. This ensures that the Exhaust gas flow, the guide vane 6 always loaded with a defined torque, thereby undesirable fluttering and swinging of the vane during operation of the vane Exhaust gas turbine can be largely suppressed.
- the outwardly guided part of the blade shaft 18 is at two radially against each other staggered locations 23, 24 stored.
- the two bearings 23, 24 are in the as Section of the housing 4 used support ring 16 is arranged. As between support ring 16 and flow channel 14 of the relief ring 17 is located, the support ring 16 in the radial Direction are large without being concerned that he is undesirably high is exposed to thermal stresses.
- the two bearings 23 and 24 can therefore in be arranged relatively far apart radial direction, whereby of the Lagerstellen23, 24 large bearing forces are kept away.
- the adjusting lever 20 is at its one end by plugging with the blade shank 18th connected.
- the end of the Schaufelschaft 18 two arranged on the type of forks claws, which on two plane-parallel guided holding surfaces of the blade shank 18 are attached.
- the Holding surfaces are arranged between the two bearing points 23, 24. It can be on this Way in the radial direction space can be saved.
- the Adjusting lever 20 is guided in a groove 25 of the adjusting ring 19. This groove 25 is limited by two in essentially radially guided groove walls, which seen in the circumferential direction of the adjusting ring 19 have a distance from each other, which is slightly larger than the diameter of the actuating lever 20.
- the depth of the groove 25 is dimensioned slightly larger than the diameter of the Stellhebels 20. By this dimensioning of the groove 25 is a jam-free leadership of Adjusting lever 20 when executing a caused by turning the adjusting ring 19 Pivoting movement about the pivot axis 8 ensured. By a on the lever 20 attached and supported on the collar 19 spacers 26 ensures that the connector between the lever 20 and blade shank 18 in the execution of Pivoting movement is not affected.
- FIG 3 is a lever 20 of another embodiment of the nozzle 5 after Invention shown. Also, this lever is attached to the blade shank 18. in the Difference to the previously described lever 20 is at this lever 20, however, a fastened from a sheet steel, sheet-shaped fuse element 33 is attached.
- This Securing element 33 has an elastically deformable fork-shaped end 34 on.
- the fork 34 is first spread and engages after completion of the Aufsteckvorganges the blade shank 18 to form a spreading.
- To the Adjusting lever 20 to keep as free of play in the radial direction are in the cylindrical executed blade shank 18 only in the region of the connector with the lever 20 two of Figure 3 apparent plan guided side surfaces molded.
- the Moment transmission from the adjusting ring 19 on the blade shank is characterized by a particularly high level of security, since in contrast to the spacer 26 the Securing element 33 during operation of the diffuser only with relatively small Strain deformation forces is charged.
- the adjusting ring 19 is mounted with its outer surface on Wälzkörpem. As in particular from 4, it can be seen that these rolling elements are pivotally mounted on the support ring 16 one-armed lever 27 executed. At the end remote from the support ring 16 end of each lever 27th a gate is provided into which a guide ring 19 attached to the guide cam 28 engages. Further, in this end of the lever and a recording of a portion of the adjusting ring 19 serving guide groove 29 formed with a on the outer surface of the adjusting ring 19th resting, opposite to the outer surface curved and serving as Wälz Structure Groove base.
- a channel 31 is formed in the support ring 16, a channel 31 is formed.
- This channel can after removal of a cap 32 ( Figure 4) with a coolant source, such as Output of a charge air cooler to be connected.
- the channel 31 is over the Housing passages for the blade shafts 18 guided in the flow channel 14. in the Channel-guided compressed air ensures effective cooling of the nozzle 5 and prevents by overflow into the flow channel 14, the entry of hot exhaust gases in the Diffuser.
