Compression efficiency is caused to reduce, while the utilization rate of lubricating oil is not high and noise is big, during the work time, gas generates a large amount of
Noise, lubricating oil are largely taken out of along air-flow, and the loss of lubricating oil in compression chamber causes to occur lacking lubricating oil in compression chamber
The case where, accelerate the inner body abrasion of compressor.
Utility model content
A kind of in order to overcome the deficiencies of the prior art, the utility model provides scroll compressor.
The technical solution of the utility model is as follows:
A kind of scroll compressor, including shell, base, eccentric shaft and compression assembly, the eccentric shaft are rotatably set
In on the base, the eccentric end of the eccentric shaft is connect with the compression assembly, the other end of the eccentric shaft and described outer
Shell connection, the compression assembly includes quiet disk and Moving plate, the Moving plate and the eccentric axis connection, the quiet disk and the Moving plate
Connection, the quiet disk and the cage connection form sealing cavity, are equipped with air inlet, gas vent, drainback passage in the quiet disk
And air cavity, the drainback passage, the air inlet and gas vent are connect with the air cavity respectively, and noise reduction is equipped in the air cavity
Part.
Further, the acoustic element is silencing cotton.
Further, the Moving plate and the quiet disk are tightly connected to form compression chamber.
Further, one end of the drainback passage connects the air cavity, described in the other end connection of the drainback passage
Compression chamber.
It further, further include screw, the quiet disk is fixedly connected with the shell through the screw.
Further, sealing ring is additionally provided between the quiet disk and the shell.
Beneficial effect, when the scroll compressor operates, the Moving plate and the quiet disk are in compressed gas, the gas
After the active force that lubricating oil in chamber generates it by air pressure, the lubricating oil enters the compression chamber by drainback passage,
Oil return efficiency is improved, increases lubricant effect and cooling effect, while high pressure gas enters the air cavity and causes gas and produce
Raw pneumatic noise greatly reduces noise after the effect of the acoustic element, improves service performance and service life.

Specific embodiment
In order to make the purpose of this utility model, technical solution and technical effect are more clearly understood, below with reference to specific reality
Mode is applied to be described further the utility model.It should be understood that specific embodiment described herein, be only used for explaining this reality
With novel, it is not used to limit the utility model.
Shown in a kind of scroll compressor of the utility model preferred embodiment, Fig. 1 and Fig. 2, including shell 1, base 2,
Eccentric shaft 3 and compression assembly, the eccentric shaft 3 is rotatably set on the base 2, for transmitting power, the eccentric shaft 3
Eccentric end connect with the compression assembly, the other end of the eccentric shaft 3 is connect with the shell 1, the compression assembly packet
Quiet disk 10 and Moving plate 11 are included, the Moving plate 11 is connect with the eccentric shaft 3, and the quiet disk 10 is connect with the Moving plate 11, described
Quiet disk 10 connect to form sealing cavity with the shell 1, and the sealing cavity is low pressure chamber at work, sets in the quiet disk 10
There are air inlet 101, gas vent 102, drainback passage 103 and air cavity 104, the air cavity 104 is height when scroll compressor works
Pressure area, the drainback passage 103, the gas vent 102 and the air inlet 101 are connect with the air cavity 104 respectively, the gas
Acoustic element 105 is equipped in chamber 104, gas first passes around the air inlet 101, subsequently enters the air cavity 104, the acoustic element
105 can effectively reduce the noise of gas generation, while enter the air cavity 104 by the air inlet 101 along air-flow
Lubricating oil, return in the screw compressor under the action of pressure difference by the drainback passage 103, adequately utilize compression
Machine inner space, designs the screw compressor drainback passage 103 of reasonably optimizing, therefore compressor can be prevented because lubricating oil stream
