Definitions
- the invention relates to the field of exhaust gas turbochargers for supercharged internal combustion engines. It relates to a compressor of such an exhaust gas turbocharger.
- Exhaust gas turbochargers are used to increase the performance of internal combustion engines, in particular reciprocating engines.
- an exhaust gas turbocharger usually has a centrifugal compressor and a radial or axial turbine.
- bypass mass flows result, which allow a shift towards smaller or larger volume flows in the region of the surge line, ie in the area of minimum volumetric flow promotion and in the area of the intake limit, ie in the region of maximum volumetric flow promotion with identical machines without bypass.
- the stabilizer space is formed as an elongate, narrow channel.
- the object of the invention is to improve a compressor by a new structural design of the stabilizer space.
- the inner compressor housing that is, the part inside the outer spiral housing is formed in one piece. This is the flow channel from the axial
- Compressor wheel limiting housing part is formed as a component. The deflected from the axial to the radial direction flow channel is on this
- the stabilizer space In the interior of the one-piece housing of the stabilizer space is arranged, which expands according to the invention via a variable in the axial direction, large radial height. This results in an optimal turbulence of the recirculation flow through the stabilizer space.
- the stabilizer space is opened via two openings to the flow channel. Upstream of the compressor wheel is arranged a radial inlet opening and downstream of the leading edge of the compressor wheel and in the overlap area to the inlet of a radial contour groove.
- the arranged between the circumferential openings ring land forms a part of the Strömungsungsanalwand and is connected via a plurality of retaining ribs with the inner compressor housing.
- the holding ribs can be provided with vibration-reducing measures.
- the holding ribs can be arranged obliquely with respect to the radial direction. Or they can be profiled and / or arranged twisted around their own axis. Several holding ribs can be arranged obliquely opposite one another in order to increase the rigidity and thus to achieve a high natural frequency of the intake geometry.
- this variant allows for different compressor stages implement a variable spiral cross-section.
- thermal insulation may be applied to the housing wall which separates the stabilizer space from the flow channel. Thereby, the heat input can be reduced to the air circulating in the stabilizer room.
- sound-absorbing means can be arranged in the stabilizer room without additional structural measures.
- Fig. 1 shows a compressor housing with an integrated insert wall
- Fig. 2 shows the opposite inclined position of the holding ribs against the center without misalignment of the stiffening ribs.
- Fig. 1 shows a section of an inventively designed radial compressor, as it is used for example in exhaust gas turbochargers.
- the outer compressor housing 20 and the inner compressor housing 10 are divided in the region of the spiral housing.
- the outer compressor housing 20 is fixed to the right of the bearing housing, not shown, on the back of the compressor wheel 40.
- the inner compressor housing 10 comprises a part of the spiral and the housing parts forming the flow channel upstream of the spiral, the insert wall 12 and, upstream of the compressor wheel 40, the compressor inlet.
- the stabilizer chamber 60 is opened via two openings to the flow channel.
- a radial inlet groove 14 is arranged, which is bounded by a housing part in the intake, for example, a housing part of a muffler or intake, and the compressor inlet.
- the cross section of the stabilizer space 60 is due the spiral is not constant along the circumference.
- the average radial height of the stabilizer space is at least approximately two-thirds of the axial distance between inlet groove 14 and contour groove 13. Thanks to the uneven and large radial height of the stabilizer space, an optimal turbulence of the recirculation flow through the stabilizer chamber results, which has a positive effect on the generated Noise affects.
- the not constant along the circumference cross-sectional profile provides additional acoustic improvement.
- the inner compressor housing 10 with axially extending
- Stiffening ribs 15 are selectively reinforced. As a result, any loads can be counteracted, which due to the distribution of the spiral geometry to two
- Housing parts in the inner compressor housing may arise.
- Stiffening ribs can be selected according to the expected load.
- the stiffening ribs may optionally be formed twisted around the loader axis.
- the stiffening ribs may optionally be arranged obliquely to the radial direction.
- the edge of the stiffening ribs can optionally be rotationally symmetrical.
- the stiffening ribs may optionally have a conical shape.
- the separation of the wall insert geometry in the compressor inlet through the contour groove requires a separate attachment of the annular web 11.
- This attachment is realized by radially outwardly directed retaining ribs 16.
- vibration-reducing measures can be implemented.
- the retaining ribs can optionally be formed rotated about its axis.
- the holding ribs can optionally be inclined against the radial direction.
- the retaining ribs may have different deviations from the radial direction.
- the holding ribs can also be arranged skewed in opposite directions.
- the holding ribs can optionally be equipped with a round, conical or elliptical profile or with a flow profile.
- the design of the retaining ribs allows the installation of optional sound-absorbing measures in the stabilizer space with little additional constructive auxiliary measures.
- the overall very soft structure of the integrated inner compressor housing has a positive effect on the behavior in the event of bursting of the compressor wheel.
- the long housing parts can be easily deformed and absorb a large part of the energy stored in the compressor wheel.
- guide vanes 25 of the diffuser are optionally arranged on the integrated housing wall 10.
- the profiles are provided as a ring during casting of the integrated inner compressor housing and milled to the required mass during finishing.
