Outlet carries out Oil-gas Separation with the through hole 221 on base bearing 22 and in entrance oil-gas separation chamber 400.Oil structure 4 and compressor
It is convenient to coordinate between structure 2, thus enormously simplify the internal structure of compressor 100, facilitates the production and manufacture of compressor 100.
In another specific example, as depicted in figs. 1 and 2, compression mechanism 2 further includes demarcation strip 26, demarcation strip 26 with
Housing 1 coordinates so that accommodating chamber is separated into high pressure chest 11 and low pressure chamber 12, and cylinder assembly 21, base bearing 22 and supplementary bearing 23 are all provided with
In in high pressure chest 11, base bearing 22 is arranged on one end of the adjacent divider 26 of cylinder assembly 21, and motor 3 is arranged in low pressure chamber 12.
Accommodating chamber is separated into high pressure chest 11 and low pressure chamber 12 by using demarcation strip 26, can to avoid base bearing 22 due to pressure differential and
Deform, avoid cylinder assembly 21 from being deformed because deforming base bearing 22, thus improve 100 reliability of operation of compressor.Into
One step, air-fuel mixture chamber 261, air-fuel mixture chamber 261 and at least one cylinder are limited between base bearing 22 and demarcation strip 26
211 air exit 2111 connects, and air-fuel mixture chamber 261 passes through the through hole 221 on base bearing 22 and oil and gas import 401
Connection.
Specifically, low-pressure gas is entered in cylinder chamber by the Suction gas inlet of cylinder 211, and height is compressed into cylinder chamber
The gas of pressure, gases at high pressure are discharged into air-fuel mixture chamber 261 by air exit 2111, and gases at high pressure enter air-fuel mixture chamber
The through hole 221 on base bearing 22 is passed sequentially through after in 261 and oil and gas import 401 enters in oil-gas separation chamber 400, carries out oil
Qi leel from.It is convenient to coordinate between oil structure 4 and compression mechanism 2, thus enormously simplify the internal structure of compressor 100, side
Just the production and manufacture of compressor 100.
Further, the side of the adjacent divider 26 of base bearing 22 is equipped with muffler 5, and muffler 5 has silencing cavity 51
And the inlet and outlet connected with silencing cavity 51, import are connected with the air exit 2111 of at least one cylinder 211, outlet with
Air-fuel mixture chamber 261 connects.The gases at high pressure discharged by the air exit 2111 of cylinder 211, which are initially entered in muffler 5, to disappear
After sound, then it is discharged into air-fuel mixture chamber 261, oil-gas separation chamber 400 is finally entered by air-fuel mixture chamber 261 again.Disappeared by setting
Sound device 5 can reduce the exhaust noise of compressor 100, thus improve the riding quality of compressor 100.
In the specific example shown in Fig. 1-Fig. 2, the cylinder assembly 21 of compressor 100 includes two cylinders 211, and this two
A cylinder 211 independently works, and two cylinders 211 are set in left-right direction, and the exhaust of the cylinder 211 of neighbouring supplementary bearing 23 goes out
Mouth 2111 is arranged on supplementary bearing 23, and the air exit 2111 of the cylinder 211 of neighbouring base bearing 22 is arranged on base bearing 22, base bearing
The side of 22 adjacent divider 26 is equipped with muffler 5, and the side of the remote demarcation strip 26 of supplementary bearing 23 also is provided with muffler 5,
Connected positioned at the outlet of the muffler 5 on right side with air-fuel mixture chamber 261, the high pressure gas being compressed to form in right cylinder 211
Body is discharged into the muffler 5 on right side by the air exit 2111 on base bearing 22 and carries out noise reduction, is pressed in left hand cylinder 211
The gases at high pressure formed that contract are discharged into the muffler 5 in left side by the air exit 2111 on supplementary bearing 23 carries out noise reduction, left side
The silencing cavity 51 of muffler 5 disappear by communicating passage (not shown) with air-fuel mixture chamber 261 or with the muffler 5 on right side
Sound chamber 51 connects, so that the air exit 2111 of cylinder assembly 21 is connected with air-fuel mixture chamber 261, so that by gas
The gases at high pressure that cylinder component 21 is discharged, which will fully enter, carries out Oil-gas Separation in oil structure 4, thus further reduce compressor
100 oil spitting amount.In addition, coordinate conveniently, thus greatly between the oil structure 4 and compression mechanism 2 of the compressor 100 of the present embodiment
The big internal structure for simplifying compressor 100, facilitates the production and manufacture of compressor 100.
According to the refrigeration system of the utility model second aspect embodiment, including according to the above-mentioned first aspect of the utility model
