+ Guarantee of low compression ratio at every state, smaller host engine leakage, higher volume efficiency.
+ The two-segment rotors are directly driven by a beyel wheel so that each rotor obtains the best line speed and the
compression transfer efficiency is the highest.
It drops oil mist spray cooling at stage intervals, so as to make the
entire compression process close to the compression, thus
improvingthe compression adiabatic efficiency.
+ The rotor and bearing have small load; the constant operation of the host engine ensures long life.
