A partition, to advantageously ensure that the normal use of middle baffle assembly 10.
For double-cylinder compressor shown in fig. 6, first order high pressure forces second partition 2 to deform, second level high pressure
Force first partition 1 deform, since first partition 1 and the middle part interdigit of second partition 2 separate, first partition 1 and second every
The deformation of plate 2 is independent of each other, and is thus conducive to the deflection for reducing first partition 1 and second partition 2, prevents from excessively becoming because of partition
Screen failure caused by shape.
In the specific example of Fig. 3-Fig. 4, it is only necessary to open up the circle being recessed to the left on the right side of first partition 1
Connected in star can guarantee exist between first partition 1 and second partition 2 when contacting first partition 1 and second partition 2
Gap.It is of course also possible to open up the circular groove being recessed to the right on the left side of second partition 2, or simultaneously
Groove is opened up on one partition 1 and the end face of second partition 2, can equally be guaranteed between existing between first partition 1 and second partition 2
Gap.
The first bolt hole 15 is offered in first partition 1, the second bolt hole 25 is offered on second partition 2, bolt is worn
First partition 1 and second partition 2, can be fixed together by the first bolt hole 15 and the second bolt hole 25.Optionally, the first bolt
The quantity of hole 15 and the second bolt hole 25 can be multiple, thus be conducive to increase consolidating between first partition 1 and second partition 2
Determine reliability.In the specific example of Fig. 1-Fig. 2, the first bolt hole 15 and the second bolt hole 25 are five and one a pair of position
It answers.
