In the above-described embodiments, in the air-conditioning system course of work, the rotor 3 of pump assembly starts to rotate, when 3 turns of rotor
When moving to the first 10 position of sliding vane groove, the first slide plate 9 is slided into the first sliding vane groove 10, the first air supply passage of block 8, this
Although when the first suction inlet 5 and the first air supply passage 8 be connected to compression chamber jointly, the first air supply passage 8 will not be to pressure
Contracting chamber carries out tonifying Qi, therefore compression chamber can will not occur in compression chamber from normal suction at the first suction inlet 5 due to tonifying Qi
It is excessive into causing stress, tonifying Qi to the first suction inlet 5 flow back the problem of.When rotor 3 is along the mistake being rotated further clockwise
Cheng Zhong, rotor 3 cross the first suction inlet 5, are not connected mutually between the first suction inlet 5 and the first air supply passage 8 at this time, first
The continuation of suction inlet 5 is connected with suction muffler carries out air-breathing, and the first air supply passage 8 is connected with discharge chamber.At this time the first slide plate 9 towards
The direction for skidding off the first sliding vane groove 10 is slided, and since sliding distance is too small, the first air supply passage 8 is still blocked, can not
It opens, the first air supply passage 8 still will not provide tonifying Qi to discharge chamber.
After rotor 3 is rotated further certain angle, the first slide plate 9 increases towards the distance that the first sliding vane groove 10 skids off at this time
Add so that the first slide plate 9 skids off the port position of the first air supply passage 8, opens the first air supply passage 8, and the first tonifying Qi is led to
Road 8 is connected with the first tonifying Qi import 7, and tonifying Qi is entered through the first tonifying Qi import 7 and the first air supply passage 8 in discharge chamber, to pressure
Contracting machine carries out tonifying Qi.When rotor 3 is turned at 10 highest distance position of the first sliding vane groove of distance, the first slide plate 9 moves to maximum at this time
Sliding position, the first air supply passage 8 are still opened, and continue to carry out tonifying Qi to discharge chamber.
After rotor 3 continues to be rotated clockwise to certain angle, the pressure in discharge chamber gradually increases at this time, works as discharge chamber
It, can be at this time under the action of the first check valve 11 when interior pressure is increased above the superfeed pressure in the first air supply passage 8
High pressure refrigerant in discharge chamber is effectively prevent to ensure the compression performance of compressor along 8 reverse reflux of the first air supply passage, so as to
The compression efficiency being effectively improved under the conditions of high pressure ratio.
When rotor 3 is continued to rotate between the first air supply passage 8 and first exhaust outlet 6, the first air supply passage 8 at this time
It is separated, and the first air supply passage 8 and the first suction inlet 5 are connected to suction muffler, the first slide plate 9 jointly with first exhaust outlet 6
Slided into the first sliding vane groove 10, block is in the port of the first air supply passage 8 so that the first air supply passage 8 and the first tonifying Qi into
Mouth 7 disconnects connection, and the first air supply passage 8 is no longer to suction muffler tonifying Qi.By above-mentioned cyclic process, can be effectively ensured when the
When one air supply passage 8 and the first suction inlet 5 are connected to suction muffler jointly, the first air supply passage 8 is closed；When the first air supply passage
8 with first exhaust outlet 6 be connected to discharge chamber jointly when, the first air supply passage 8 superfeed pressure be greater than or equal to discharge chamber in
It opens during pressure, is closed when superfeed pressure is less than pressure in discharge chamber, improve the tonifying Qi efficiency of compressor 1, and effectively anti-
When only pressure is excessive in discharge chamber, gaseous coolant is out of compression chamber along 8 reverse flow of the first air supply passage to the first tonifying Qi
Tonifying Qi reflux occurs for import 7, reduces tonifying Qi resistance, enhances tonifying Qi effect.
Certainly, in practical work process, the first check valve 11 can also be saved, by rationally designing the first air supply passage
8 avoid being vented cavity pressure with the communicating position of compression chamber and the communicating position of the first air supply passage 8 and the first sliding vane groove 10
The tonifying Qi reflux problem of excessive generation.
