It is located in cylinder chamber, slide plate 200 is located in vane slot 414 and the tip 204 of slide plate is only supported on the piston 42, and slide plate 200 is root
According to the slide plate 200 of the above embodiment of the present invention.It is understood that being provided with eccentric part 432 on bent axle 43, it is enclosed on outside piston 42
On eccentric part 432.So as to constitute the compression chamber of refrigerant after being assembled by piston 42, slide plate 200 and cylinder 41.
When rotary compressor 100 works, bent axle 43 motor 3 turning effort lower band piston 42 around the axle center of cylinder 41
Eccentric motion is done in rotation, and slide plate 200 is in the presence of the tail part exhaust high pressure of slide plate 200 only to piston 42 and with the bias of piston
Cycle linear reciprocating motion is done in rotation, and the volume ultimately formed in cylinder 41 periodically changes, and then realizes cylinder 41
To the compression process of refrigerant.
Rotary compressor 100 according to embodiments of the present invention, by setting slide plate according to the above embodiment of the present invention
200, so as to ensure that the wear resistance of slide plate 200 can meet the use requirement and slide plate 200 of engineering technology and be moved through
The close property in side in journey, and then reduce the manufacturing cost of rotary compressor 100 and the difficulty of technique productions.
According to some embodiments of the present invention, rotary compressor 100 also includes demarcation strip 2, and demarcation strip 2 is located on housing 1
Will be separated into high pressure chest a and low pressure chamber b in housing 1, air intake duct 12 is connected with low pressure chamber b, and blast pipe 11 and high pressure chest a connects
Logical, demarcation strip 2 is located in low pressure chamber b provided with assembling through hole, motor 3, and pump assembly 4 is located in high pressure chest a, one end of bent axle 43
Coordinate through assembling through hole with rotor 32, assembling through hole coordinates with bent axle 43 or the sealing of base bearing 44, and air entry 413 passes through air-breathing
Passage 22 is connected with low pressure chamber b.It follows that refrigerant is entered in low pressure chamber b from the air intake duct 12 on housing 1, sent out in motor 3
In the presence of the heat gone out, refrigerant is exchanged heat in low pressure chamber b, so as to can not only reduce the temperature of motor 3, can also be made
Liquid refrigerant evaporation into gaseous state.And then compared with prior art, the rotary compressor 100 of the embodiment of the present invention can be cancelled
Reservoir structure, reduces the volume and weight of rotary compressor 100, while ensure that the reliability of motor 3, and improves electricity
The performance of machine 3, increases the rotary speed of motor 3, improves the reliability and operating efficiency of rotary compressor 100.Again due to logical
Cross demarcation strip 2 and be separated out high pressure chest a and low pressure chamber b, therefore base bearing 44 can be avoided to be deformed due to pressure differential, it is to avoid
Cylinder 41 is deformed because being deformed base bearing 44, improves the reliability of operation of rotary compressor 100.The setting of other demarcation strip 2, makes
Pump assembly 4 drainback passage is shorter, distance is closer to reducing the volume of rotary compressor 100, it is achieved thereby that rotation pressure
The miniaturization of contracting machine 100.Improve the reliability and operating efficiency of rotary compressor 100.It is understood that in high pressure chest a
Provided with lubricating oil to be lubricated to pump assembly 4.
The course of work of rotary compressor 100 is：Refrigerant outside rotary compressor 100 is entered low by air intake duct 12
After pressing in chamber b, exchanged heat to reduce the temperature of motor 3 in low pressure chamber b, while making liquid refrigerants absorb heat and flash to gas
State, gaseous refrigerant is entered in the air entry 413 of cylinder 41 by air intake passage 22, and refrigerant is compressed into height in cylinder 41
