Compressor having a guide vane assembly with a radially variable outflow

Abstract

A compressor is disclosed. The compressor has at least one guide vane assembly which can be adjusted to change the outflow angle, and a rotor which is connected downstream of the guide vane assembly. The guide vane assembly and rotor are arranged between a housing and a hub of the compressor. The guide vane assembly is divided in the direction of extension from the housing to the hub into two or more sections which can be radially adjusted relative to one another, or has a clearance radially in the direction of extension, the clearance allowing a substantial amount of flow to pass.

         14 . A compressor, comprising:
 a hub;   a housing;   a guide vane assembly, wherein the guide vane assembly is adjustable to change an outflow angle; and   a rotor which is disposed downstream of the guide vane assembly in a flow direction;   wherein the guide vane assembly and the rotor are arranged between the housing and the hub;   and wherein the guide vane assembly is divided in a direction of extension from the housing to the hub into two or more sections which are radially adjustable relative to one another.   
     
     
         15 . The compressor according to  claim 14 , further comprising a second guide vane assembly arranged essentially in succession from the guide vane assembly in the flow direction, wherein the second guide vane assembly is divided in a direction of extension from the housing to the hub into two or more sections which are radially adjustable relative to one another, and wherein at least one of the guide vane assembly and the second guide vane assembly is adjustable independently of the other guide vane assembly and the second guide vane assembly to change the outflow angle. 
     
     
         16 . The compressor according to  claim 14 , wherein the two or more sections are rotatable relative to one another. 
     
     
         17 . The compressor according to  claim 14 , wherein the two or more sections each have an outer shape that is changeable relative to one another. 
     
     
         18 . The compressor according to  claim 14 , further comprising an adjusting drive and wherein a first guide vane assembly section has a transmission device, wherein energy is passable from the adjusting drive through the transmission device to radially adjust a second guide vane assembly section relative to the first guide vane assembly section. 
     
     
         19 . The compressor according to  claim 14 , wherein the guide vane assembly leaves a clearance in the compressor radially in the direction of extension and wherein the clearance allows a substantial amount of flow to pass. 
     
     
         20 . The compressor according to  claim 15 , wherein at least one of the guide vane assembly and the second guide vane assembly leaves a clearance in the compressor radially in the direction of extension and wherein the clearance allows a substantial amount of flow to pass. 
     
     
         21 . The compressor according to  claim 19 , wherein the clearance is disposed on a side of the hub. 
     
     
         22 . The compressor according to  claim 20 , wherein the clearance is disposed on a side of the hub. 
     
     
         23 . The compressor according to  claim 19 , wherein the clearance is disposed on a side of the housing. 
     
     
         24 . The compressor according to  claim 20 , wherein the clearance is disposed on a side of the housing. 
     
     
         25 . The compressor according to  claim 14 , wherein the guide vane assembly is an inlet guide vane assembly. 
     
     
         26 . The compressor according to  claim 14 , further comprising a drive device attached to the housing, wherein the guide vane assembly is adjustable by the drive device. 
     
     
         27 . The compressor according to  claim 14 , further comprising a drive device attached to the hub, wherein the guide vane assembly is adjustable by the drive device. 
     
     
         28 . An engine comprising a compressor according to  claim 14 .
