It is understood that stage portion 23, bending part 24, connection bump 25 and flanging 26 on airway assembly 2 are permissible
Specifications and models combination in any design according to airway assembly 2 and compressor 100, this is not especially limited by the present invention.Optional
Ground, airway 21 is made up of at least one in copper, copper alloy, ferrum, ferroalloy and ferrum copper facing.It is to say, airway assembly 2
In multiple airways 21 can be made up of the one of which in copper, copper alloy, ferrum, ferroalloy and ferrum copper facing, it is also possible to by copper,
Multiple in copper alloy, ferrum, ferroalloy and ferrum copper facing is made.Wherein, two adjacent airways 21 can use same material
Material is made, it would however also be possible to employ two kinds of different materials are made, and this is not construed as limiting by the present invention.
Specifically, can be provided with transition part 27 at least two airway 21 at least one, transition part 27 can be one
Individual or multiple.Wherein, transition part 27 can by the tube wall of airway 21 towards compression chamber 331, in the airway assembly 2
The direction of mandrel line tilts to extend.For example, referring to Fig. 3, Fig. 4, Fig. 6, Fig. 8, Fig. 9 and Figure 10, on two adjacent airways 21
It is equipped with transition part 27, and transition part 27 is formed approximately at the middle part of airway assembly 2.And for example, with reference to Fig. 5, Fig. 7 and Figure 11,
Internal layer airway in two airways 21 being connected is provided with transition part 27, and outer layer airway is formed as straight tube.Thus, just
Coordinate with connecting tube 12 and compression chamber 331 in airway assembly 2.
According to some embodiments of the present invention, compressor 100 can be single cylinder compressor or multicylinder compressor.Wherein, when
When compressor 100 is single cylinder compressor, as it is shown in figure 1, cylinder assembly 33 includes a cylinder, now base bearing 31 is located at this gas
The upper end of cylinder, supplementary bearing 32 is located at the lower end of this cylinder.When compressor 100 is multicylinder compressor (not shown), air cylinder group
Part 33 includes multiple such as two cylinders, can be provided with dividing plate between adjacent two cylinders, and base bearing 31 is located at the gas of the top
The upper end of cylinder, supplementary bearing 32 is located at the lower end of the cylinder of bottom.
Compressor 100 according to embodiments of the present invention, efficiently reduces the heat biography between adjacent two airway 21
Lead, thus efficiently reduce the heating to the gas flowing through airway assembly 2, reduce suction superheat, and then improve
The refrigerating capacity of compressor 100, and improve efficiency and the efficiency of compressor 100.Additionally, also significantly reduce compressor 100
Difficulty of processing, reduce the processing cost of compressor 100.
