Most of the compressors used in turbochargers today are radial compressors.
The air is suctioned axially by the rotation of the compressor wheel and accelerated in the wheel to high speeds. The accelerated air leaves the compressor wheel radially toward the diffusor.
In the diffusor, this kinetic energy is converted into pressure energy. In addition, the flow is delayed, pressure and temperature rise nearly without losses. This is achieved by the constant expansion of the flow cross-section within the spiral housing, in which the air is collected and the speed is reduced up to the compressor outlet.
BAHMÜLLER offers various concepts and combination processing for the efficient complete machining of turbocharger rotors and shafts. What's more, there are various configuration options for conversion flexibility or single variant mass production.
