    The invention relates to a connection adapter for a turbine. The invention also relates to a turbine with a connection adapter.
    From practice it is known to clean the turbine and the turbine nozzle of an exhaust gas turbocharger during operation, namely the turbine rotor of the turbine, at defined time intervals. In principle, two different methods are known for this, namely wet cleaning with liquid, in particular with water, and dry cleaning with granules. For this purpose it is necessary to supply the cleaning agent to the turbine, namely the turbine housing, in order to be able to direct the respective cleaning agent for cleaning the turbine in a defined manner, in particular at the turbine rotor and turbine guide apparatus of the turbine.
    It is also known from practice that a turbine housing of a turbine consists of a turbine inflow housing and a turbine outflow housing, with the turbine inflow housing and turbine outflow housing being able to be installed in different angular positions to one another. This then also has an influence on the supply of the respective cleaning agent to the turbine housing, for which purpose it is necessary with turbines known from practice to have different variants of pipes or cleaning agent feed lines available for different relative positions between the turbine inflow housing and the turbine outflow housing. This is a disadvantage.
    Proceeding from this, the invention is based on the object of creating a novel connection adapter for a turbine and a turbine with such a connection adapter.
    This object is achieved by a connection adapter according to claim 1. The connection adapter according to the invention has a base body. The base body has a first axial end section for connecting the connection adapter to the turbine housing and an opposite, second axial end section for connecting a dry cleaning agent feed line to the connection adapter, the connection adapter being connectable to the turbine housing via the first axial end section in such a way that one of the second axial end section in the direction of the first axial end section extending dry cleaning agent guide channel of the base body coaxially to a turbine rotor of the turbine. The base body furthermore has a radial section for connecting a liquid cleaning agent feed line to the connection adapter, a liquid cleaning agent guide channel of the base body being formed in this radial section, which is separated from the dry cleaning agent guide channel via at least one longitudinal channel extending in the axial direction, radially outwardly adjoining the dry cleaning agent guide channel a groove formed on the first axial end section and extending in the circumferential direction around the dry cleaning agent guide channel is coupled.
    With the connection adapter according to the invention, it is possible to supply both dry cleaning agent and liquid cleaning agent to a turbine in a defined manner, without the need to have different variants of pipes or cleaning agent feed lines available for different relative positions between the turbine inflow housing and turbine outflow housing.
    Regardless of the selected relative position between the turbine inflow housing and turbine outflow housing, the connection adapter according to the invention can always be mounted on the turbine housing that the alignment of the same to pipes or cleaning agent feed lines remains unchanged.
    The connection of supply lines for cleaning agents is independent of the relative position between the turbine inflow housing and turbine outflow housing by the connection adapter.
    The turbine according to the invention is defined in claim 5.
    Preferred developments of the invention emerge from the subclaims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being restricted thereto. 1 shows a section from a turbine together with a connection adapter according to a first exemplary embodiment of the invention; Fig. 2 shows a cross section through Fig. 1; FIG. 3 shows a further partial cross-section through FIG. 1; FIG. 4 shows a section from a turbine together with a connection adapter according to a second exemplary embodiment of the invention; 5 shows a section from a turbine together with a connection adapter according to a third exemplary embodiment of the invention; FIG. 6 shows a partial cross section through FIG. 5; FIG. FIG. 7 shows an alternative to FIG. 6.
    Fig. 1 shows a perspective section of a turbine 10 according to the invention in the area of a turbine inflow housing 11 of the turbine 10, wherein a connecting flange 12 is formed on the turbine inflow housing 11, on which a connection adapter 13 according to the invention is mounted.
    The connection adapter 13 has a base body 14 with a first axial section 15 for connecting the connection adapter 13 to the connection flange 12 of the turbine housing 11 and a second, opposite axial section 16 for connecting a dry cleaning agent supply line, not shown, to the connection adapter 13 The two axial sections 15, 16 can also be referred to as axial end sections. They are positioned at opposite axial ends of the base body 14.
    The connection adapter 13 is connected via the first axial section 15 of the base body 13 to the connection flange 12 and thus to the turbine housing 11 in such a way that a dry cleaning agent duct 17 of the base body extending from the second axial section 16 in the direction of the first axial section 15 16 runs coaxially to a non-visible turbine rotor of the turbine. A longitudinal center axis of the dry cleaning agent guide channel 17 of the base body 14 of the connection adapter 13 accordingly coincides with an axis about which the turbine rotor rotates. Then, when a dry cleaning agent feed line is connected to the second axial section 16, the dry cleaning agent provided by the dry cleaning agent feed line can be conducted via the dry cleaning agent guide channel 17 of the base body 14 of the connection adapter 13 in the direction of the turbine housing 11.
    As can best be seen from Fig. 2, a dry cleaning agent introduction channel 18 is introduced into the connection flange 12 of the turbine housing 11, which is aligned with the dry cleaning agent guide channel 17 of the connection adapter 13 and via which the dry cleaning agent is ultimately introduced into the turbine or not shown turbine rotor and turbine nozzle can be directed.
    Viewed in the axial direction of the base body 13, a radial section 19 for connecting a liquid cleaning agent feed line, not shown, to the connection adapter 13 is formed between the two axial sections 15 and 16 of the base body 13. In this radial section 19, a liquid cleaning agent guide channel 20 of the base body 13 is formed, which is coupled to a groove 22 via at least one longitudinal channel 21 extending in the axial direction and radially outwardly adjoining the dry cleaning agent guide channel 17, which is formed on the first axial section 15 of the base body 13 and which extends in the circumferential direction like a ring around the dry cleaning agent guide channel 17 of the base body 13. The groove 22 can also be referred to as an annular channel.
    When a liquid cleaning agent feed line is connected to the radial section 19, the liquid cleaning agent provided by the liquid cleaning agent feed line can be passed through the liquid cleaning agent guide channel 20 of the base body 14 of the connection adapter 13, the at least one longitudinal channel 21 and the groove 22 in the direction of the turbine housing 11 become.
    The liquid cleaning agent guide and dry cleaning agent guide in the base body 14 of the connection adapter 13 are separated from one another.
    In the direction of the first axial end 15 of the base body 13, both dry cleaning agent and liquid cleaning agent can therefore be performed independently of one another, namely the dry cleaning agent exclusively in the axial direction via the dry cleaning agent guide channel 17, which extends from the second axial section 16 in the direction of the first axial section 15 extends, and the liquid cleaning agent extends in the radial direction and also in the axial direction starting from the radial section 19 in the direction of the first axial section 15 via the liquid cleaning agent guide channel 20 of the radial section 19 and the at least one longitudinal channel 21 into the groove 22 on the first axial section 15th
    In order to guide the liquid cleaning agent into the interior of the turbine housing in a defined manner and to direct it towards the turbine rotor to be cleaned, at least one liquid cleaning agent injection channel 23 is introduced into the connection flange 12 of the turbine housing 11, which is connected to the groove 22 on the first axial section 15 of the connection adapter 13 communicates. Liquid cleaning agent, which accordingly enters the groove 22 from the at least one longitudinal channel 21, can be introduced into the interior of the turbine housing from the groove 22 via the at least one liquid cleaning agent injection channel 23 and sprayed onto the turbine rotor and turbine nozzle, not shown.
    The connection adapter 13 is inserted with the first axial end 15 in a recess 24 of the connection flange 12 of the turbine housing 11 at least partially sealed. In order to mount and fix the connection adapter 13 on the turbine housing 11, a flange 25 is used in the exemplary embodiment of FIGS. 1 to 3, which engages the second axial end 16 of the base body 14 on the base body 13 and through which the fastening screws 26 extend into the connection flange 12 of the turbine housing 11 extend into it.
    A clamping force can be applied to the connection adapter 13 via the fastening screws 26, with which the connection adapter 13 is pressed against the connection flange 12 of the turbine housing 11. The flange 25 engaging the second axial section 16 is supported on a projection 27 formed on the second section 16 of the base body 14.
    Then, when the fastening screws 26 are loosened in the embodiment of FIGS. 1 to 3, the connection adapter 13 can be rotated continuously in the circumferential direction. The flange 25 can also be rotated accordingly in order to clamp or fix the connection adapter 13 on the turbine housing 11 without the fastening screws 26 colliding with the radial section 19 of the connection adapter 13.
    Regardless of the orientation of the connection flange 12 of the turbine housing 11 in the circumferential direction, the same orientation can therefore always be guaranteed for the connection adapter 13 by rotating the connection adapter 13 in the opposite direction by an angle of the same amount when the connection flange 12 is rotated. In this respect, cleaning agent feed lines can remain unchanged. The orientation of the second axial section 16 and of the radial section 19, to which cleaning agent feed lines can be connected, can be kept unchanged regardless of the orientation of the turbine housing 11.
    4 shows a modification of the embodiment of FIGS. 1 to 3, in which the flange 25 through which the fastening screws 26 extend is an integral part of the second axial section 16 of the base body 14 of the connection adapter 13. In the exemplary embodiment in FIG. 4, the connection flange 25 and the base body 14 of the connection adapter 13 are therefore not formed in two parts, but in one piece and thus in one piece.
    With additional bores in the connection flange 25 of FIG. 4, through which the fastening screws 26 can extend, the connection adapter 13 of FIG. 4 can be rotated and mounted in defined angular steps to the connection flange 12 of the turbine housing 11, namely in the one shown Embodiment by angular steps of preferably 15 °. While fastening bores on the connection flange 12 of the turbine housing 11 have an angular division of 30 °, the multiple through bores on the flange 25 allow a 15 ° angular division to be provided for the rotatability of the connection adapter 13 relative to the connection flange 12 of the turbine housing 11.
    In FIG. 4, the flange 25 formed integrally on the base body 14 can also be shifted in the axial direction onto the first end 15 in order to realize advantages in terms of installation space.
    Another modification of the connection adapter 10 according to the invention is shown in FIGS. 5, 6 and 7. In FIGS. 5, 6 and 7, a clamping claw 28 is used to fasten the connection adapter 13 to the connection flange 12 of the turbine housing 11, which is attached to the connection flange 12 of the turbine housing 11 and on the other hand on the first axial section 15 of the connection adapter 13. Fastening screws 26 extend through the clamping claw 28 into the connection flange 12 of the turbine housing 11 in order to apply a clamping force for fastening the connection adapter 13 to the turbine housing 11.
    When the fastening screws 26 are loosened, the connection adapter 13 can in turn be rotated relative to the turbine housing 11, namely continuously in the embodiment of FIGS. 1 to 3.
    6 and 7 differ in that in FIG. 6 a shoulder 29 is introduced into the connecting flange 12 of the turbine housing 11, whereas in FIG. 7 a corresponding shoulder 30 is formed on the clamping claw 28. The size or radial extension of this shoulder 29, 30 defines the contact surface of the clamping claw 28 on the connecting flange 12 and thus the surface pressure between these assemblies.
    The seal between the connection adapter 13 and the turbine housing 11 takes place at least via the clamping between these components and the engagement of the first axial section 15 of the connection adapter 13 in the recess 24 made on the connection flange 12 of the turbine housing 11. such as a sealing ring, can be arranged between the first axial section 15 of the connection adapter 13 and the connection flange 12 of the turbine housing 11.
