Housing for a radical compressor

Abstract

A housing for a radial compressor is comprised of at least two housing parts manufactured of plastic material for receiving a compressor wheel and for forming a spiral-shaped compressor passage, wherein into the housing between compressor wheel receptacle and compressor passage an annular space is introduced that annularly surrounds the compressor wheel and into which a stabilization element is introduced.

1 . A housing for a radial compressor, comprised of at least two housing parts ( 2 ,  3 ,  4 ) manufactured of plastic material for receiving a compressor wheel ( 7 ) and for forming a spiral-shaped compressor passage ( 8 ), wherein in the housing ( 1 ) between a compressor wheel receptacle ( 5 ) and the spiral-shaped compressor passage ( 8 ) a hollow space is introduced, the hollow space being an annular space ( 10 ) that surrounds the compressor wheel ( 7 ) with at least one stabilization element disposed in the annular space ( 10 ). 
     
     
         2 . The housing according to  claim 1 , wherein the annular space ( 10 ) is delimited by two housing parts ( 3 ,  4 ). 
     
     
         3 . The housing according to  claim 2 , wherein the housing parts that delimit the annular space ( 10 ) are embodied as inwardly positioned bearing shell ( 4 ) forming the compressor wheel receptacle ( 5 ) and as compressor front part ( 3 ). 
     
     
         4 . The housing according to  claim 3 , wherein the bearing shell ( 4 ), on the side facing away from the compressor wheel receptacle ( 5 ), forms an annular groove ( 16 ) that forms a part of the annular space ( 10 ). 
     
     
         5 . The housing according to  claim 1 , wherein the housing is of a three-part configuration and comprises the compressor front part ( 3 ), a compressor rear wall ( 2 ), and the inwardly positioned bearing shell ( 4 ). 
     
     
         6 . The housing according to  claim 5 , wherein the compressor front part ( 3 ) has a contact area ( 15 ) with the bearing shell ( 4 ) and a further contact area ( 14 ) with the compressor rear wall ( 2 ). 
     
     
         7 . The housing according to  claim 1 , wherein the contact areas ( 14 ,  15 ) between the housing parts ( 2 ,  3 ,  4 ) are arranged at a spacing to the spiral-shaped compressor passage ( 8 ). 
     
     
         8 . The housing according to  claim 7 , wherein the contact areas ( 14 ,  15 ) are positioned adjacent to the intake opening ( 6 ) of the housing ( 1 ). 
     
     
         9 . The housing according to  claim 1 , wherein the housing parts ( 2 ,  3 ,  4 ) are welded to one another, in particular by ultrasonic welding. 
     
     
         10 . The housing according to  claim 1 , wherein a stabilization element in the annular space ( 10 ) is embodied as fill material. 
     
     
         11 . The housing according to  claim 10 , wherein the fill material is comprised of plastic material. 
     
     
         12 . The housing according to  claim 1 , wherein the stabilization element in the annular space ( 10 ) is embodied as a separate component, for example, as a fill hose ( 11 ). 
     
     
         13 . The housing according to  claim 1 , wherein the housing parts ( 2 ,  3 ,  4 ) are manufactured of thermoplastic material and in particular producible by injection molding. 
     
     
         14 . The housing according to  claim 13 , wherein the housing parts are comprised of polyphenylene sulfide (PPS).
