Meanwhile medium pressure grade refrigerant gas is pressed into pressure gas anechoic room (31) during tracheae (34) enters in, with first order pressure
Contracting gas is sufficiently mixed；Then, it via middle pressure air intake duct (35), is drawn into upper cylinder (20), and passes through upper piston (22) rotation
Transhipment is moved and medium pressure gas is compressed to high pressure by the reciprocating motion of upper slide plate (24), is then discharged into high pressure from upper bearing (metal) (26)
In exhausting silencer room (29)；The high pressure gas come out from high pressure gas anechoic room (29), by determining for outer rotor motor (12)
The gap of runner and rotor (17) between sub (16), rises to housing (11) inner top, in the process to outer rotor motor (12)
There is certain cooling effect；Then refrigerant gas and mist lubrication oil are detached at top, and mist lubrication oil condenses into liquid
Drop is flowed into along housing (11) side inner walls in the oil sump of compression motor spindle；The refrigerant gas of high pressure passes through external rotor electric simultaneously
Runner on the outside of the rotor (17) of motivation (12) between housing (11) inner wall flows to the middle part of compressor, via exhaust pipe (14)
Discharge；
Meanwhile by the rotation of bent axle (18), the lubricating oil in housing (11) bottom, via the Vertical Square at bent axle (18) center
To oilhole (39) rise, by be located at midway lateral feed bore flow out, be supplied to the bearing of bent axle (18) and each compression chamber
It is interior, each moving component of compressor is made to obtain effectively lubricating.
