Preferably, exhaust passage is arranged on the outer surface of axle journal.
Preferably, exhaust passage includes the one or more oblique straight troughs extended obliquely out along the outer surface of axle journal.
Preferably, exhaust passage includes the helicla flute extended spirally along the outer surface of axle journal.
Preferably, meeting D-d between the diameter d of axle journal and the diameter D of axle sleeve<=0.03~0.1mm.
Preferably, the lead angle of helicla flute is 10 to 40 degree.
Preferably, the section of exhaust passage is semicircle, triangle or rectangle.
According to another aspect of the present utility model there is provided a kind of pump assembly, including upper flange, the upper flange is above-mentioned
Upper flange.
According to another further aspect of the present utility model there is provided a kind of compressor, including pump assembly, the pump assembly is upper
The pump assembly stated.
Using the technical solution of the utility model, upper flange includes flange body and muffler, and flange body includes axle journal,
Muffler includes axle sleeve, and axle sleeve is set in outside axle journal, and axle sleeve coordinates with journal packing, and forms connection exhaust outlet and exterior space
Exhaust passage, exhaust passage is extended obliquely out along the axial direction of axle sleeve.Because exhaust passage is located between axle sleeve and axle journal, and it is edge
The axial direction of axle sleeve is extended obliquely out, therefore during refrigerant flows, exhaust passage diagonally direction deflecting always, hence in so that
Oil gas can be separated using the difference of respective movement inertia, so that the oil mass discharged with refrigerant is reduced, reduction compression
Machine oil spitting amount, improves the service behaviour of compressor.
Brief description of the drawings

Fig. 2 is the cross section structure diagram of the upper flange of the utility model embodiment.
Description of reference numerals：1st, flange body；2nd, muffler；3rd, axle journal；4th, axle sleeve；5th, exhaust outlet；6th, exhaust passage.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as to this practicality
New restriction.
Found by research, compressor tells oily big, when mainly also coming from pump housing exhaust, a large amount of vaporific oil gas of discharge are mixed
Compound, such mist is just flooded with inside whole compressor, as compressor is discharged, into air-conditioning system pipeline.Therefore,
If it is intended to the oil spitting amount of reduction compressor, it may be considered that the oil content in reducing the refrigerant discharged from compressor.
With reference to shown in referring to Fig. 1 and Fig. 2, according to embodiment of the present utility model, upper flange includes flange body 1 and noise reduction
Device 2, flange body 1 includes axle journal 3, and muffler 2 includes axle sleeve 4, and axle sleeve 4 is set in outside axle journal 3, and axle sleeve 4 is matched somebody with somebody with the sealing of axle journal 3
Close, and form the exhaust passage 6 of connection exhaust outlet 5 and exterior space, axial direction of the exhaust passage 6 along axle sleeve 4 is extended obliquely out.
Because exhaust passage 6 is located between axle sleeve 4 and axle journal 3, and extended obliquely out along the axial direction of axle sleeve 4, therefore cold
During matchmaker is flowed, exhaust passage diagonally direction deflecting always, hence in so that oil gas utilizes the difference of respective movement inertia
It can separate, so as to reduce the oil mass discharged with refrigerant, reduce oil spitting amount of compressor, improve the workability of compressor
Energy.
Preferably, the discharge chamber connected with the exhaust outlet 5 of flange body 1 is formed between muffler 2 and flange body 1, should
Discharge chamber is located between exhaust passage 6 and exhaust outlet 5, and together with exhaust passage 6 and exhaust outlet 5.Discharge chamber can provide larger
Exhaust space so that from exhaust outlet 5 discharge compressed gas can more easily enter in exhaust passage 6, can also
The quality of fit between exhaust outlet 5 and exhaust passage 6 is reduced, exhaust efficiency is improved.
Exhaust passage 6 can be arranged on axle journal 3 and/or axle sleeve 4, namely exhaust passage 6 can be arranged on the outer of axle journal 3
On perisporium, on the internal perisporium that axle sleeve 4 can also be arranged on, or the periphery wall and axle sleeve 4 of axle journal 3 are correspondingly arranged at simultaneously
On internal perisporium, it can specifically be configured as needed, it is necessary to ensure the capacity of compressor.
In the present embodiment, exhaust passage 6 is arranged on the outer surface of axle journal 3, is on the one hand the fairly simple convenience of processing, energy
Technology difficulty is enough reduced, processing cost is reduced, is on the other hand due to that the thickness of axle journal 3 is thicker, the thinner thickness of axle sleeve 4, therefore will
Exhaust passage 6 is arranged on the outer surface of axle journal 3, will not be caused excessive influence to the overall construction intensity of axle journal 3, is effectively ensured
The structural strength of axle journal 3, while can also be that the size design of exhaust passage 6 can meet requirement.
In wherein one embodiment, exhaust passage 6 can include one or many extended obliquely out along the outer surface of axle journal 3
Individual oblique straight trough.Oblique straight trough shows as the outer surface curve deflecting around axle journal 3 on the outer surface of axle journal 3, therefore when refrigerant is in row
During being flowed in gas passage 6, it can produce and especially separate due to the circumferential deflecting of oblique straight trough so that lubricating oil can be more
Ground is flowed back in upper flange along oblique straight trough, continues to be lubricated each part of compressor so that enter the cavity of compressor
The oil mass for being inside then discharged out compressor is greatly reduced, so as to effectively reduce the oil spitting amount of compressor, improves the work of compressor
Performance.
Preferably, in the present embodiment, exhaust passage 6 includes the helicla flute extended spirally along the outer surface of axle journal 3, due to
The deflecting angle of helicla flute it is larger, it is necessary to around axle journal 3 outer Monday it is all or it is many week after can just flow out outside exhaust passage 6,
Therefore it can be more prone to realize the separation of the lubricating oil in refrigerant, preferably lubricating oil can be retained in compressor, drop
The oil spitting amount of low compressor.
Preferably, D-d is met between the diameter d of axle journal 3 and the diameter D of axle sleeve 4<=0.03~0.1mm, can form envelope
The spiral exhaust passage closed, while so that the gap between axle journal 3 and axle sleeve 4 will not be excessive, it is ensured that gas is from closed spiral
Passage flows so that helical duct can effectively reduce the oil spitting amount of compressor.
Preferably, the lead angle of helicla flute is 10 to 40 degree, by increasing capacitance it is possible to increase the distance that refrigerant flows in exhaust passage 6,
Improve oil gas separation so that Oil-gas Separation is more thorough, further the oil spitting amount of reduction compressor.
The section of exhaust passage 6 is semicircle, triangle or rectangle, or other shapes, it is preferable that in this reality
Apply in example, the section of exhaust passage 6 is semicircle.
According to embodiment of the present utility model, pump assembly includes upper flange, and the upper flange is above-mentioned upper flange.
According to embodiment of the present utility model, compressor includes pump assembly, and the pump assembly is above-mentioned pump assembly.
Certainly, above is preferred embodiment of the present utility model.It should be pointed out that for the ordinary skill of the art
For personnel, on the premise of the utility model general principle is not departed from, some improvements and modifications can also be made, these improvement
Protection domain of the present utility model is also considered as with retouching.
