The overlooking the structure diagram for the spinning rollers compressor middle pump body that Fig. 3 is provided by the embodiment of the present invention.
Wherein, 100 it is upper flange, 200 be cylinder, 201 be the second dilatation hole, 300 is lower flange, 301
It is bottom silencer for the first dilatation hole, 400,500 is that exhaust structure, A are lower muffler chamber.
Embodiment
The core of the present invention is to disclose a kind of pump housing, to increase the cavity volume of lower silencing cavity；The present invention
Another core be to disclose a kind of spinning rollers compressor, to improve the compression performance of compressor.
Hereinafter, embodiment is illustrated referring to the drawings.In addition, embodiments illustrated below is not to right
It is required that the described content of the invention plays any restriction effect.In addition, composition represented by example below
Full content is not limited to necessary to the solution as the invention described in claim.
Fig. 2 to Fig. 3 is referred to, the spinning rollers compressor middle pump body that Fig. 2 is provided by the embodiment of the present invention
Main structure diagram；The vertical view for the spinning rollers compressor middle pump body that Fig. 3 is provided by the embodiment of the present invention
Structural representation.
The pump housing in the embodiment of the present invention, including upper flange 100, cylinder 200, lower flange 300 and lower noise reduction
Device 400, upper flange 100 and lower flange 300 are arranged on the two ends of cylinder 200, upper flange 100 and lower flange 300
Exhaust structure 500 is provided with, bottom silencer 400 is arranged on drop-down flange, and bottom silencer 400 is with
Surround lower muffler chamber A between flange 300, lower flange 300 by bottom silencer 400 wrap up in the range of also set up
There is the first dilatation hole 301, the first dilatation hole 301 is connected with lower muffler chamber A.
