Provided with the first chamber and second chamber being serially connected in chamber, the exhaust noise silencing chamber, the first chamber and second chamber point
It is not fixed on by the fixed block of bottom in exhaust noise silencing chamber, the first chamber is connected with the gas outlet of steam vent, described
First chamber is connected by through hole respectively with second chamber, second chamber with exhaust noise silencing chamber.
As a kind of optimal technical scheme of the present utility model, the first chamber and second chamber are all spherical or hemisphere
Shape, the diameter with diameter greater than second chamber of the first chamber.
As a kind of optimal technical scheme of the present utility model, the noise reduction layer is made up of quieter material.
As a kind of optimal technical scheme of the present utility model, the quieter material is mineral wool, mineral wool, felt or wood
Silk etc..
As a kind of optimal technical scheme of the present utility model, the middle part of the pedestal is provided with crankshaft hole.
As a kind of optimal technical scheme of the present utility model, the middle part of the cylinder head is provided with cylinder holes.
The beneficial effects of the utility model are：
The utility model sets one layer of noise reduction layer being made up of quieter material in steam vent, can be by many of its own
Permeability, absorbs to part acoustic energy, noise caused by reduction fraction pulsation；Set and be serially connected in exhaust noise silencing chamber
First chamber and second chamber, and first chamber and second chamber is of different sizes, while multistage noise reduction is reached due to
Chamber of different sizes has the intrinsic frequency of oneself, the audio different therefore, it is possible to eliminate height, disappears so as to substantially increase
Audio is really；The utility model uses single silencing cavity, and the volume of cylinder body can be obviously reduced, so that reduce the volume of compressor,
And then reduce the cost of manufacture of compressor.

Embodiment
The utility model row is further described presently in connection with accompanying drawing.
As shown in Figures 1 to 4, a kind of good refrigeration compressor cylinder body of performance muffler, including pedestal 1, the pedestal 1
Top one end is provided with and the integrally formed cylinder head 2 of pedestal 1, and the middle part of the pedestal 1 is provided with crankshaft hole 9, the cylinder head 2
Portion is provided with cylinder holes 10, and the side of cylinder holes 10 is provided with steam vent 3, and the inwall of the steam vent 3 is bonded with one layer of noise reduction by glue
Layer 4, the noise reduction layer 4 is made up of quieter material, and the quieter material is mineral wool, mineral wool, felt or wood wool etc.；Institute
Air inlet and the gas outlet for stating steam vent 3 are horn-like all for what is expanded outwardly, and the position of the side of cylinder head 2 is located on the pedestal 1
Place is provided with exhaust noise silencing chamber 5, provided with the first chamber 6 and second chamber 7 being serially connected in the exhaust noise silencing chamber 5, and described the
One chamber 6 and second chamber 7 are fixed in exhaust noise silencing chamber 5 by the fixed block 8 of bottom respectively, the two ends of shown fixed block 8
It is connected respectively by way of welding with exhaust noise silencing chamber, first chamber and second chamber, the first chamber 6 and steam vent 3
Gas outlet be connected, the first chamber 6 and second chamber 7, second chamber 7 and exhaust noise silencing chamber 5 pass through through hole phase respectively
Connection.
As shown in figure 4, the first chamber 6 and second chamber 7 are all hemispherical, the first chamber 6 and second chamber 7
Hemispherical cross-section be all open state, the hemispherical cross-section of the first chamber 6 disappeared by way of seamless welding with exhaust
