In the housing 1 of compressor 100, temperature and suction and discharge pressure differential deltap P of compressor 100 have larger relation.Work as compressor
When 100 suction and discharge pressure differential deltap P are less, the temperature in housing 1 is relatively low.Conversely, the temperature in housing 1 is higher.
In compressor 100 initial start stage, or when compressor 100 suction and discharge pressure differential deltap P is relatively low, the temperature in housing 1
Relatively low, now, the coefficient of elasticity of extension spring 35 is relatively low, therefore stage clip 34 and extension spring 35 to the collective effect of slide plate 2 based on pressure,
Can ensure that compressor 100 normally starts, and no slide plate 2 sound when compressor 100 works under relatively low suction draught head.
With the increase of compressor 100 suction and discharge pressure differential deltap P, the temperature in housing 1 increases, and the coefficient of elasticity of extension spring 35 shows
Write and increase, lead to stage clip 34 and extension spring 35 suitable to the active force of slide plate 2, the power slide plate 2 being produced is less, compressor 100
Efficiency can be lifted by a small margin.
With the increase further of compressor 100 suction and discharge pressure differential deltap P, the temperature in housing 1 also increases further, extension spring
35 coefficient of elasticity increases further so that extension spring 35 is significantly greater than the pressure to slide plate 2 for the stage clip 34 to the pulling force of slide plate 2, this
When stage clip 34 and extension spring 35 to the collective effect of slide plate 2 based on pulling force, the inner contact force with piston of slide plate 2, fall can be reduced
Low compression machine 100 power, improves compressor 100 efficiency.
According to yet another alternative embodiment of the invention, as shown in figure 4, elastic parts includes：Receiving member 36, air bag 37 with
And second spring 38, receiving member 36 is located on housing 1, has accommodating chamber 361, inside accommodating chamber 361 and housing 1 in receiving member 36

(for example, the lower end in Fig. 4) is connected away from one end (i.e. outer end) of cylinder axis with slide plate 2, wherein when suction draught head becomes
During change, the Volume Changes of air bag 37 to be to drive slide plate 2 to move in vane slot by second spring 38.
Specifically, referring to Fig. 4, compressor 100 housing 1 has one for accommodating the accommodating chamber 361 of air bag 37,
One air bag 37 is installed in accommodating chamber 361, one end of second spring 38 is connected with air bag 37, the other end of second spring 38 and slide plate
2 outer ends connect.
Pressure in compressor 100 housing 1 is the pressure at expulsion of compressor 100 it is contemplated that compressing in actual moving process
Machine 100 pressure of inspiration(Pi) scope is less, therefore when compressor 100 suction and discharge pressure differential deltap P is larger, the pressure in compressor 100 housing 1
Power is also higher.
In compressor 100 initial start stage, or when compressor 100 suction and discharge pressure differential deltap P is relatively low, the pressure in housing 1
Relatively low, now the volume of air bag 37 is larger, and one end away from cylinder of therefore second spring 38 is shorter with cylinder relative distance, the
Two springs 38 are applied to the larger pressure of slide plate 2 it is ensured that compressor 100 normally starts or is compressor 100 suction air pressure
No slide plate 2 sound when difference Δ P is relatively low.
With the increase of compressor 100 suction and discharge pressure differential deltap P, the pressure in housing 1 increases, and the volume of air bag 37 reduces,
Therefore one end away from cylinder of second spring 38 and cylinder relative distance relative increase, second spring 38 is applied to slide plate 2
Power significantly declines, and compressor 100 efficiency is lifted.
With the increase further of compressor 100 suction and discharge pressure differential deltap P, the pressure in housing 1 also increases further, air bag
37 volume reduces further, and therefore one end away from cylinder of second spring 38 and cylinder relative distance increase further, phase
To for, second spring 38 is changed into extension spring 35 from stage clip 34, and the power being applied to slide plate 2 becomes pulling force, can reduce slide plate 2 inner with
The contact force of piston, thus reducing the power of compressor 100, improves the efficiency of compressor 100.
Compressor 100 such as rotary compressor according to embodiments of the present invention, is applied to slide plate 2 by changing elastic parts
Plus the size of power and/or direction, to ensure that compressor 100 is starting moment, or in compressor 100 suction draught head relatively
Hour, elastic parts is applied to the enough pressure of slide plate 2, thus ensureing that in compressor 100 running, slide plate 2 is close to work
Plug, it is to avoid compressor 100 starts the anomaly such as exception or slide plate 2 sound, simultaneously larger in compressor 100 suction and discharge pressure ratio
When, the direction of the power that elastic parts applies to slide plate 2 can change, and elastic parts applies pulling force to slide plate 2, can reduce slide plate 2
Contact force between tip and piston, reduces frictional force herein further, reduces compressor 100 power such that it is able to play,
Improve the effect of compressor 100 efficiency.
