Shown in 2, central pressure gas supplementing opening 81 with system pressure connect when, the cold-producing medium through one stage of compression for entering in middle pressure chamber 8 with
The gas for being entered in middle pressure chamber 8 by middle pressure gas supplementing opening 81 is entered in the second compression cylinder jointly, by two-stage compression cylinder
72 carry out two-stage compression, are discharged to two grades of pressures through the condenser of two-stage compression by the second exhaust port of two-stage compression cylinder 72
Outside contracting cylinder 72, and compressor is discharged by connecting the gas outlet 31 of condenser, in Fig. 1, arrow a, b, d, e are the stream of cold-producing medium
Dynamic direction, arrow c is the direction of middle pressure QI invigorating, and in Fig. 2, arrow b, f, g, d are the flow direction of cold-producing medium, and arrow c is mended for middle pressure
The direction of gas.
The present embodiment is by air inlet 21 is arranged on motor side body 2, and air inlet 21 and vaporizer are directly connected
Logical so as to be directly entered 1 side of motor from the cold-producing medium of vaporizer gas-liquid mixed state out, and in the rotation acting heating of motor 1
In the presence of make the cold-producing medium of liquid be evaporated to gaseous state, final cause the cold-producing medium for entering into pump assembly after motor 1 complete
Portion is gaseous state, can be prevented effectively from the cold-producing medium for entering in pump assembly and be mixed with liquid and affect the performance of compressor, therefore may be used
To save for carrying out gas-liquid separation to evaporator outlet cold-producing medium, to prevent the cold-producing medium for entering in pump assembly to be mixed with liquid
Liquor separator, and then liquor separator can be connected outside compressor, so as to reduce volume and the car air-conditioner system of compressor
The integral installation space of system.Further, the present embodiment is set by directly not connected aerofluxuss side body 3 with motor side body 2
Put, on the one hand space in space in motor side body 2 and aerofluxuss side body 3 can be separated so that space in aerofluxuss side body 3
Discharging in cylinder becomes high pressure chest under gases at high pressure effect, and in motor side body 2, space becomes low pressure chamber relatively, is easy to from steaming
Sending out device cold-producing medium out 1 side of motor is sucked from the air inlet 21 of motor side body 2；On the other hand can make through 1 side of motor
And be all evaporated to gaseous cold-producing medium enter in pump assembly by cylinder suck and be compressed into high-pressure gaseous refrigerant discharge.
The automobile-used rotary compressor of the present embodiment, by the flange arrangement of pump assembly cover plate by motor side body 2
In space and aerofluxuss side body 3, space separates, can between flange arrangement of the flange arrangement of motor side body 2 with cover plate with
Sealing gasket 6 is respectively provided between the flange arrangement of aerofluxuss side body 3 and the flange arrangement of cover plate, is realized in motor side body 2
In space and aerofluxuss side body 3, space sealing separates, and effectively prevents the high pressure gas body drain that in aerofluxuss side body 3, space cylinder is discharged
To in motor side body 2 in space, enable space in motor side body 2 that the state of relatively low pressure is maintained at, be easy to motor side
Air inlet 21 on housing 2 is from vaporizer efficiently inspiration cold-producing medium.
As disposable embodiment, the present embodiment on the basis of above-described embodiment, space and electricity in aerofluxuss side body 3
In pusher side housing 2, space replaces with direct connection.At this moment in aerofluxuss side body 3 in space and motor side body 2, outside pump assembly
Space interconnect and with identical pressure, directly the air inlet 21 of connection vaporizer is arranged on motor side body 2, with
Sample can be realized the cold-producing medium of the gas-liquid mixed state from vaporizer out and be directly entered 1 side of motor, and send out in the rotation acting of motor 1
The cold-producing medium of liquid is made to be evaporated to gaseous state in the presence of heat, the final cold-producing medium for causing to enter into pump assembly after motor 1
All gaseous states, can be prevented effectively from the cold-producing medium for entering in pump assembly and be mixed with liquid and affect the performance of compressor, so
Liquor separator equally can be connected outside compressor, so as to realize reducing the whole of the volume of compressor and air conditioning system for vehicle
Body installing space.
