Or valve block baffle and valve block on cylinder 1.
As shown in Figure 1, the second air entry 311 is that length direction is stretched out along slide plate 31 or the strip of retracted orientation setting is long
Slot.When designing the maximum length of the second air entry 311 exposing slide plate accommodating cavity side, setting is held when slide plate 31 stretches out slide plate first
When setting chamber longest, the size along the stretching of slide plate 31 or retracted orientation that the second air entry 311 exposes slide plate accommodating cavity side is H, and
The eccentricity of eccentric rotary component is set as e, the distance between head to head of slide plate 31 of the second air entry 311 is X, then
H=2e-X.According to the needs of practical operation, the value range of H can be set as 0.1~0.2mm.The size of H cannot be excessive
Cannot be too small, need reasonably to set the size range of its exposing.
On the basis of the above, the second air entry 311 is further described from slide plate accommodating cavity will be stretched out to i.e. will be complete
The process of full reduced time slide plate accommodating cavity.Slide plate is compressed to completely to rotate origin in slide plate accommodating cavity with eccentric rotary component,
When eccentric rotary component turns to 128 ° by origin, the second air entry 311 starts to stretch out slide plate accommodating cavity, eccentric rotary component
128 ° of corners be exactly air intake passage opening angle.When eccentric rotary component continues to rotate to 180 °, slide plate 31 stretches out slide plate
Accommodating cavity apart from longest, the second air entry 311 exposes the distance of slide plate accommodating cavity also longest, the size preferably 0.1~
Between 0.2mm, specific size is determined according to design requirement.When eccentric rotary component continues to rotate, slide plate starts to bounce back, thus
The distance for driving the second air entry to expose slide plate accommodating cavity is also gradually reduced, until when continuing to rotate to 232 °, the second air entry
311 closings, 232 ° of corners of eccentric rotary component are exactly the closing angle of air intake passage.So far, slide plate accommodating can be calculated
- 128 °=104 ° of air-breathing angular range area α=232 ° of chamber.Above-mentioned is only the air-breathing angle of distance the second air intake passage of explanation
Degree, is not limited to that, the opening angle and closing angle of air intake passage can be changed according to design requirement.

Converge in the return line of dispenser inlet, two sets of air-conditioning systems share a liquid separator of compressor.
Air-conditioning system at work, enters the first air-conditioning system by the compressed gas that main vent 81 is discharged in the present embodiment
9 first exhaust access is entered the second exhaust access of the second air-conditioning system 10 by the compressed gas that auxiliary exhaust port 82 is discharged.
Two temperature air-conditioning system provided in this embodiment, the original suction airway dysfunction of compressor is constant, keeps another way row
Gas is discharged from the exhaust pipe of shell upper end, connect with the second servo loop of refrigeration system after shell, and it is logical to form second exhaust
Road.
Existing compressor only has the function of one air-breathing parameter of output and an exhaust parameter, if desired realizes multiple suctions
The output of gas parameter or exhaust parameter then needs multiple compressors to combine to realize, two temperature in the prior art such as shown in Figure 4
Air-conditioning system, two groups of air-conditioning systems are independent of one another, realized respectively by two groups of compressors, while cost performance is not high, to installation
Space is also more demanding.The utility model makes a compressor have the double function of single suction, can effectively substitute former needs two
Compressor is just able to achieve the two temperature air-conditioning system of the double-exhaust parameter of driving.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
