2) Compressor
The compressor, which is connected to the turbine over the one and same shaft to form a rotat-
ing body, takes in and compresses ambient air with rotating force transmitted from the turbine
shaft. Then, the compressed air is delivered to the intake stake. This is the operating principle
of the compressor.
3) Bearings
(1) Thrust bearing
The turbine wheel creates thrust force. Therefore, exercise care so that the shaft is not devi-
ated from its the original position due to this thrust.
(2) Journal bearing
This journal bearing of floating type forms a dual oil film on both the inside and outside of
the bearing so that the bearing can rotate independently. As the dual oil film plays a role as
a damper, the sliding speed of the bearing surface becomes lower than the rotating speed
of the shaft, resulting in assurance of stability in its movement.
4) Sealing-Compressor shaft
The compressor is of a dual construction type composed of seal plate and seal ring to prevent
the leak of compressed air or lubricating oil.
