What is claimed is: 1. A compressor and turbine wheel for a secondary air feed device, comprising a single common component (1) which forms a combined compressor wheel and turbine wheel, the common component being designed in the form of a rotor (1) which carries compressor blades (3) on one side (12) and turbine blades (4) on an opposite side (11) of the rotor, the rotor (1) consisting of at least two materials, a metallic material and a plastic, wherein the metallic material is an alloy based on at least one of Al, Mg, Ti, Fe, Ni, in the form of one of a metal sheet, foil or casting, and the plastic is one of PEEK, PA, PFA, PPS and foams of plastic materials, and wherein the rotor (1) comprises two spaced blade discs (15) with a blade disc carrier (16) of a plastic material being disposed in the space between the two blade discs (15). 2. The compressor and turbine wheel as claimed in claim 1, wherein a sleeve (20) for attachment of the rotor to the shaft (6) is provided and connected to the rotor (1). 3. The compressor and turbine wheel as claimed in claim 1, wherein a seal (23; 28; 33; 35) is provided between a housing (26) of the secondary air feed device and the rotor (1). 4. The compressor and turbine wheel as claimed in claim 3, wherein the seal is a ring seal (23). 5. The compressor and turbine wheel as claimed in claim 3, wherein the seal is a brush seal (28). 6. The compressor and turbine wheel as claimed in claim 3, wherein the seal is a labyrinth seal (33). 7. The compressor and turbine wheel as claimed in claim 3, wherein the seal is provided with a grind-in lining (35) which is formed between the rotor (1) and a stationary guide cascade ring (40). 8. The compressor and turbine wheel as claimed in claim 1, wherein the rotor (1) is accommodated in a housing (26) of the secondary air feed device, supported on one side of the rotor (1). 9. The compressor and turbine wheel as claimed in claim 1, wherein for the rotationally fixed connection of rotor (1) and shaft (6), the rotor (1) is shrink-fitted onto the shaft (6). 10. The compressor and turbine wheel as claimed in claim 1, wherein the blades of the compressor (3) and of the turbine (4) have airfoil profiles. 11. The compressor and turbine wheel as claimed in claim 1, wherein the blade carrier (16) is formed from plastic injected between the blade discs (15) by one of injection molding and foaming.
