Guide vanes are supported in a two-part or multipart housing (32, 33). Housing separation takes place radially in the region of the bearing point (25) of the vane shaft so that the separating joint (36) between the housing parts (32, 33) leads through the bearing openings (34) which are designed to
Guide vanes are supported in a two-part or multipart housing (32, 33). Housing separation takes place radially in the region of the bearing point (25) of the vane shaft so that the separating joint (36) between the housing parts (32, 33) leads through the bearing openings (34) which are designed to hold the vane shafts. The completely round opening (34) leads to the bearing point of the vane shaft having large-area support in any position. Thus high surface pressures can be avoided.

The invention claimed is: 1. Guide device with adjustable guide vanes, which guide vanes are each connected to a vane shaft pivotally mounted in bearing openings of a housing and can be turned around the vane shaft with an adjusting lever which is connected to the vane shaft and which acts on the vane shaft, the housing comprising: a radially inner housing part; and a radially outer peripheral ring, a separating joint between the radially inner housing part and the radially outer peripheral ring passing through the bearing openings, wherein the vane shaft has at least one bearing point for support in the housing, wherein the housing has a bearing opening in which the bearing point is pivotally mounted, and wherein the vane shaft is configured for insertion into the bearing opening in the radial direction through the insertion opening in the bearing opening, the insertion opening being made narrow such that, when inserted, the vane shaft will snap into the bearing opening as a resistance is overcome. 2. Guide device as claimed in claim 1, wherein each of the bearing openings comprises two partially circular arc-shaped holes, the first of the partially circular arc-shaped holes being inlet into the radially inner housing part, and a second partially circular arc-shaped hole being inlet into the radially outer peripheral ring. 3. Guide device as claimed in claim 1, wherein the radially outer peripheral ring and the radially inner housing part surround a cavity in which the adjusting levers are located. 4. Guide device as claimed in claim 1, wherein to mount the guide device the outer peripheral ring can be pushed in the axial direction over the guide vanes located in the radially inner housing part. 5. Guide device as claimed in claim 1, wherein to mount the guide device, the outer peripheral ring can be pushed in the axial direction over the radially inner housing part together with the guide vanes located in the outer peripheral ring. 6. Guide device as claimed in claim 1, wherein the vane shaft and the adjusting lever are materially connected to one another. 7. Guide device as claimed in claim 1, wherein the guide vane, vane shaft and adjusting lever are materially connected to one another. 8. Guide device as claimed in claim 1, wherein the vane shaft has at least one bearing point for support in the housing, and wherein the bearing point is located between the adjusting lever and the guide vane. 9. Guide device as claimed in claim 1, wherein the vane shaft has a region with a reduced diameter and wherein the vane shaft with the region with reduced diameter can be inserted into the bearing opening in the radial direction through the insertion opening in the bearing opening and then can be moved in the axial direction. 10. Compressor with a diffusor with adjustable diffusor vanes, the diffusor comprising a guide device as claimed in claim 1. 11. Exhaust gas turbocharger with a compressor as claimed in claim 10. 12. Exhaust gas turbine with a guide device as claimed in claim 1. 13. Exhaust gas turbocharger with an exhaust gas turbine as claimed in claim 12. 14. Guide device with adjustable guide vanes, which guide vanes are each connected to a vane shaft pivotally mounted in bearing openings of a housing and can be turned around the vane shaft with an adjusting lever which is connected to the vane shaft and which acts on the vane shaft, the housing comprising: a radially inner housing part; and a radially outer peripheral ring, a separating joint between the radially inner housing part and the radially outer peripheral ring passing through the bearing openings, wherein the outer peripheral ring is made in several parts in a peripheral direction. 15. Guide device with adjustable guide vanes, which guide vanes are each connected to a vane shaft pivotally mounted in bearing openings of a housing and can be turned around the vane shaft with an adjusting lever which is connected to the vane shaft and which acts on the vane shaft, the housing comprising a radially inner housing part and a radially outer housing part, a separating joint between the radially inner housing part and the radially outer housing part passing through the bearing openings, which bearing openings have a round cross section and are composed of two partially circular arc-shaped holes, a first of the partially circular arc-shaped holes being inlet into the radially inner housing part, and a second partially circular arc-shaped hole being inlet into the radially outer housing part, wherein the vane shaft has at least one bearing point for support in the housing, wherein the housing has at least one of the bearing openings in which the bearing point is pivotally mounted, and wherein the vane shaft is configured for insertion into the at least one bearing opening in a radial direction through an insertion opening of the at least one bearing opening, the insertion opening being made narrow such that, when inserted, the vane shaft will snap into the bearing opening as a resistance is overcome. 16. Compressor with a diffusor with adjustable diffusor vanes, the diffusor comprising a guide device as claimed in claim 15. 17. Exhaust gas turbine with a guide device as claimed in claim 12.
