Middle pressure chamber) in Fluid pressure when being more than predetermined pressure, under the action of high pressure draught, two arms 222 will upwards (perpendicular to
Plane where Fig. 6 is upward) overturning.However, as previously mentioned, two the first apertures 1551 are diametrically opposed ground each other
Arrangement, two the second apertures 1552 are also to arrange with being diametrically opposed each other.Therefore, with the revolution of dynamic vortex component,
These pairs of apertures will undergo opening pressure successively.It is analyzed with reference to plan view shown in fig. 6, it is assumed that according to dynamic vortex component
Gyratory directions, the first aperture 1551 reaches opening pressure first, and the second aperture 1552 reaches opening pressure later.Then, it is located at
The part for being closer to its free end of the arm 222 in left side is in the work of the high pressure draught from following the first aperture 1551 outflow
It can be flipped up first under, followed by second aperture of the part far from its free end of the arm 222 on the downside of it
It is flipped up under the action of 1552.However, for the arm on right side, due to the first aperture 1551 and second on the downside of it
It is exactly the opposite in the location arrangements in aperture 1552 and the arm 222 in left side, therefore, the air-flow that the arm 222 on right side is subject to
Effect is also opposite so that the part far from its free end of the arm 222 on right side can be first pushed upwardly, followed by by
It is bordering on the part of free end.Specifically, for the arm on right side 222, pressure is opened when the first aperture 1551 reaches preset
During power, due to the first aperture 1551 farther away from the free end of the arm 222 on right side (in other words, similarly open pressure under,
First aperture 1551 on right side and the arm of force of the pivoting portions of right side arm 222 are less than first aperture 1551 and left side in left side
The arm of force of the pivoting portions of arm 222), so the arm 222 on actually right side can not be opened at this time.With dynamic vortex component
Revolution, when the second aperture 1552 closer to the free end of right side arm 222 reach it is preset opening pressure when, right side arm
222 are opened, however, the actual pressure in the first aperture 1551 corresponding to the arm of right side is with dynamic vortex component at this time
Revolution is further increased, so as to cause the capacity loss of part.As a result, due to the first aperture 1551 and the second aperture
The 1552 different location arrangement in two through holes 211, in contrast, the arm 222 in left side can be more first than the arm 222 on right side
It is flipped up and realizes exhaust, cause two arms 222 that cannot be synchronously carried out exhaust.In this way, not only it is easy to cause valve block structure
The torsional deformation of part 22, and the displacement of valve block component 22 is easily led to, so as to influence the exhaust performance of valve module.So,
It is different from the exhaust resistance of the compression chamber of valve module V20 two roughly the same pressure being in fluid communication, so as to affect scroll compression
The stability and exhaust performance of contracting machine.
In addition, it can see the stressing conditions of valve module structure shown in Fig. 4 with reference to Fig. 7.As shown in fig. 7, when by described in

21 three of plate is bonded together by pin 25, and its junction angle shown in Fig. 7 is located at the left side (reference chart of holding member
C in 7).In joint place, holding member 23 is acted on by upward supporting force F2.Since valve block component 22 not covers
It covers entire substrate 21 and sets, so that not by the part that valve block component 22 covers and the first table of holding member on substrate 21
There are certain gap g between face (to depend on the thickness of valve block component, the gap is substantially in the range of 0.004-0.154mm
It is interior).In addition, the presence of the inclined-plane section 2311 on holding member 23 causes the corresponding portion in inclined-plane section 2311 and substrate 21
Between there is also larger gaps.Such structure is arranged such that holding member 23 is formed as cantilever beam structure, so as to cause stress
The phenomenon that concentration.From the schematic diagram of Fig. 7 the inclined of 23 top of holding member is evenly applied to it can also be seen that comparing and comparing
Pressure F1, the bottom of holding member 23 are only supported the effect of power F2 in part (left side in Fig. 7).Therefore, holding member
23 easy run-off the straights, so as to cause contacted between holding member 23 and valve block component 22 by face become line contact (be generally in
At D shown in fig. 7) so that serious abrasion is generated on valve block component 22 at corresponding line contact position (with reference in figure 8
D at) or even be easy to cause valve block component 22 arm 222 fracture, so as to reduce the service life of valve module.
