  • the invention relates to an exhaust-gas turbocharger according to the preamble of claim 1.
  • An exhaust-gas turbocharger of said type is known from DE 10 2007 060 415 Al .
  • Said known exhaust-gas turbocharger has a shut-off device with first and second guide grate elements, wherein the second guide grate element is guided in a transiatorially movable fashion in a sleeve or bush which must be inserted into the turbine housing.
  • the shut-off device has a shut-off sleeve which is inserted into a groove of the turbine housing and which is guided therein in a transiatorially movable fashion, it is no longer necessary for a separate sleeve or bush to be produced and arranged in the turbine housing.
  • the groove in which the shut-off sleeve is guided is formed directly into the material of the turbine housing itself proceeding from the bearing housing side.
  • the groove has only a depth which is selected to be as small as possible. Said groove depth corresponds to the width of the shut-off sleeve.
  • the outer diameter of the shut-off sleeve is smaller than the diameter of the turbine housing on the bearing housing side, such that after the groove is formed into the material of the turbine housing, the shut-off sleeve can be inserted into the groove proceeding from the bearing housing side.
  • shut-off device into the turbine housing upstream of the turbine inlet, in order for example to realize a so-called "turbo engine brake” with the capability to allow the exhaust-gas recirculation rate to be increased by means of regulated shut-off or throttling of the turbine channel or of the turbine channels.
  • the subclaims relate to advantageous embodiments of the invent ion.
  • the shut-off sleeve preferably has two webs which are arranged diametrically opposite one another and whose free ends are connected to an actuating device which effects the translatory movement of the shut-off sleeve within the groove.
  • the groove which is integrated into the turbine housing above the turbine wheel contour has housing apertures through the turbine housing.
  • the number of housing apertures corresponds to the number of webs, which means that at least one housing aperture is provided whose position can be freely selected, or in the case of two webs, whose positions should be selected so as to be approximately diametrically opposite one another.
  • shut- off sleeve When the sleeve is inserted into the groove, an air bearing arrangement is formed, and the webs are guided through the housing apertures so as to project out of the turbine housing on the side of the turbine outlet. It is therefore possible for the shut- off sleeve to be connected to the actuating device via a suitable lever arrangement and a fork connected thereto, wherein the fork is connected at one side to the lever arrangement and at the other side to the free ends of the webs projecti g from the turbine housing.
  • the design of the shut-off device according to the invention has the further advantage that it can be integrated into already existing turbine housings by reworking, since it is necessary merely to form the discussed groove for the shut-off sleeve into the turbine housing and to provide a number of housing apertures corresponding to the number of webs of the shut-off sleeve.

  • the exhaust-gas turbocharger 1 has a turbme 2 with a turbine wheel 3 which is arranged in a turbine housing 4.
  • the turbine housing 4 has a turbine channel 5, though it is preferable for normally two separate turbine channels to be provided, which will be described in more detail below on the basis of Figure 2.
  • the turbine channel 5 has a passage opening 6 which, as viewed in the exhaust-gas flow direction, is provided in the turbine housing 4 upstream of the turbine wheel 3.
  • shut-off device 7 which is provided downstream of the turbine channel 5 and upstream of the turbine wheel 3, for opening and closing the passage opening 6.
  • the exhaust-gas turbocharger 1 also has the other conventional parts, in particular a compressor 8 with a compressor wheel 9 in a compressor housing 10 and a shaft 1 1 on which the turbine wheel 3 and the compressor wheel 9 are arranged in the conventional way.
  • all the other parts of conventional exhaust- gas turbochargers are of course also provided, such as a bearing housing with a bearing arrangement for the shaft 11, but said parts are neither illustrated nor described because they need not be described for the explanation of the principles of the present invention.
  • Figure 2 shows a schematically simplified sectional illustration of a part of the turbine housing 4 in the region of the shut-off device 7.
  • the embodiment according to Figure 2 shows a turbine housing 4 with two adjacent channels 5, 5' separated from one another by a web 20.

The number of housing apertures 21 is dependent on the number of webs with which the shut-off sleeve 12 is provided.
  • the housing aperture 21 through the turbine housing 4 allows the webs, in the case of the illustration of Figure 2 the web 14, to extend through into the region of the turbine outlet A, such that the free end 16 of the web 14 can be connected to a fork 19 which will be described in detail below.

  • the double arrows Bl, B2 and B3 indicate the movements of the lever arrangement 18 and of the fork 19, which ultimately lead to the translatory movement T within the groove 13.
