Essentially this consists of:
- a central body in which a shaft is housed, supported by
bushings, the ends of which are connected to: the
turbine rotor and the compressor rotor;
- a turbine body and a compressor body fitted at the ends
of the centre body;
- an pressure limiter valve fitted on the turbine casing. Its
function is to choke the exhaust gas outlet (detail B),
sending a portion of the exhaust gas directly into the
exhaust pipe when the turbo charging pressure down
from the turbocharger reaches a calibrated value;
