Roller seating space space when going to inlet end wall opening, its space is maximum, and now rotor roller seating space space and air inlet are communicated, because
The gas of roller seating space is fully drained during exhaust, when exhaust is completed, and roller seating space is in vacuum state, when going to air inlet, extraneous gas
Body is to be inhaled into, in the roller seating space for entering axially into negative and positive rotor.When gas is filled with whole roller seating space, rotor air inlet side end face turns
Disembark shell air inlet, be to be closed in the gas of roller seating space.2）Compression process：Negative and positive rotor at the end of air-breathing, its female rotor 6,
The crown of male rotor 7 can be closed with body, and now gas no longer outflows in roller seating space.Its field of conjugate action is gradually moved to exhaust end.Nibble
Gradually part is small in roller seating space space between conjunction face and exhaust outlet, and the gas in roller seating space is improved by compression pressure.3）Exhaust process：When turn
The engagement end face of son is gone to when being communicated with body exhaust outlet, and gas compressed starts discharge, until crown and roller seating space are engaged
Face moves to exhaust end face, and now the roller seating space space of female rotor 6, the field of conjugate action of male rotor 7 and body exhaust outlet is 0, that is, the row of completion
Gas process, at the same time the roller seating space length between the field of conjugate action of rotor and body air inlet reach again it is most long, intake process again again
Carry out.As female rotor 6, male rotor 7 can not stall, the intermeshing tooth of each pair is successively performed identical working cycles.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modifications, equivalent substitutions and improvements made etc. should be included within the scope of the present invention.
