ABSTRACT:
In a vane type compressor, in which a plurality of radial vanes are supported on a compressor shaft and extended through a rotary piston, each vane is formed of two wall portions spaced from each other and two ring portions receiving bearings for supporting the vanes on the shaft. The wall portions and the ring portions of each vane are formed as a one-piece element which may be produced by stamping-out and bending a sheet metal. A supporting structure of kernels of aluminum disposed in a honeycomb manner is inserted between two wall portions of each vane.
