In refrigerative circle system, compressor be for future from evaporator drier gasified refrigerant be collapsed into the device of High Temperature High Pressure, in vaporizer, liquefied refrigerant is vaporized by removing heat around and cools.
But the flutter component produced when gaseous refrigerant is from compressor discharge to condenser impacts the pipeline of refrigeration cycle, thus the noise produced in refrigeration cycle and vibrations.
In order to reduce the problems referred to above, vent silencer is arranged on cylinder body to reduce the noise in the discharge passage of compressor.
Vent silencer is suitable for reducing the pulsation from the refrigeration agent of compressor discharge, and is divided into the first chamber and the second chamber that are connected to each other by connecting passage.
In addition, the first chamber by expanding channels to cylinder head, the space that the high-pressure refrigerant that cylinder head has to be provided by cylinder enters, and the second chamber is connected to discharge pipe.
In conventional practice, the noise caused by the pulsation of refrigeration agent is reduced by the vent silencer with said structure, if but the connecting passage in connection the first chamber and the second chamber provides by means of only casting technique, then and the length of connecting passage is limited, and pulsation reduction effect is also limited.
In order to overcome the problems referred to above, recently, proposed the technology that there is given inner diameter and be connected the first chamber and the second chamber with the pipeline of length, thus reduced the flutter component of refrigeration agent more.
But in this case, pipeline is exposed to the outside of cylinder body, and the inwall of the shell of victim compression machine, therefore, the installation of pipeline should be considered when designed enclosures.Especially, if Pipe installing is inner in chamber, then the size in chamber should be increased to hold pipeline wherein, thus makes the size of cylinder body become heavy undesirably.
Therefore, the space availability ratio of compressor and output are lowered.

Embodiment
Specifically describe below with reference to accompanying drawing 1 to 7, according to of the present invention, there is the example that the exhaust pulse be arranged on wherein reduces the hermetic compressor of parts.
According to the present invention, as illustrated in fig. 1 and 2, there is the hermetic compressor that the exhaust pulse be arranged on wherein reduces parts, be arranged in the machine chamber of refrigerator, and be connected to condenser (not shown) and gas refrigerant be compressed into high pressure and the refrigeration agent of compression is provided to condenser, hermetic compressor generally includes housing 1; Cylinder body 100, arranges within the case 1; And vent silencer 200 is arranged in the top of cylinder body 100 to reduce the flutter component of refrigerant emission.
The second chamber 220 that vent silencer 200 has the first chamber 210 and separates, and the first chamber 210 is connected each other by connecting passage 10 with the second chamber 220.
In addition, the first chamber 210 is connected to cylinder cap 211 by passage 212, and cylinder cap has the space of the high-pressure refrigerant held from cylinder discharge in its side, and the second chamber 220 is connected to discharge pipe 221.
In this case, connecting passage 10 for being connected to each other in the first chamber 210 and the second chamber 220, and controls the flutter component of refrigeration agent further.
Namely, after the high temperature and high pressure refrigeration agent introducing vent silencer 200 flows into the first chamber 210, it is by connecting passage 10 and be sent to the second chamber 220, thus the flow velocity of refrigeration agent is lowered, and has the refrigeration agent reducing flow velocity and be provided to condenser by discharge pipe 221.
According to the present invention, as shown in Figure 3, exhaust pulse reduces parts 20, there is similar bar shaped to add the passage length of refrigeration agent, be fixed and insert connecting passage 10, when not changing the size and shape of vent silencer 200, reducing the flutter component of refrigeration agent, namely reducing vibrations and noise.
As shown in Figures 4 to 6, reduce parts 20 according to exhaust pulse according to the present invention to comprise the groove type pulsation formed along its outer surface and reduce passage 21, and the entrance 22 communicated with each other on the longitudinal direction reducing passage 21 in pulsation on its opposite end and outlet 23.
Connecting passage 10 is fixedly secured in order to the exhaust pulse with said structure is reduced parts 20, the outer surface reducing parts 20 along exhaust pulse forms screw thread, and along connecting passage 10 formed correspond to exhaust pulse reduce screw thread on parts 20 by fastened screw thread, thus exhaust pulse reduces together with parts 20 are screwed in each other with connecting passage 10.Alternatively, exhaust pulse reduction parts 20 are tapered in their longitudinal direction and are fixed to connecting passage 10 by interference fit.
Therefore, pulsation reduces passage 21 and form the passage being used for refrigeration agent together with connecting passage 10.
When exhaust pulse reduction parts 20 are screwed in connecting passage 10, ideally, the position of the screw thread of connecting passage 10 is fixed to and length is properly adjusted according to ease of processing for exhaust pulse being reduced parts 20, and be easy to use instrument to be connected to connecting passage 10, the head 24 that exhaust pulse reduces parts 20 preferably can have one of various shape.
In addition to a circular cross-sectional shape, exhaust pulse reduction parts 20 can have multi-sided cross-sectional shape.
Therefore, pulsation reduces passage 21 and to be formed thereon or exhaust pulse wherein reduces parts 20 and installs along the inner peripheral surface connecting the first chamber 210 of vent silencer 200 and the connecting passage 10 in the second chamber 220, thus the entrance 22 that the refrigeration agent introducing the first chamber 210 reduces parts 20 through exhaust pulse reduces passage 21 with pulsation, and be sent to the second chamber 220 by outlet 23.
Namely, the length of connecting passage 10 can extend through exhaust pulse to reduce on parts 20 or in pulsation reduce passage 21, thus the flow velocity of the refrigeration agent provided to the second chamber 220 by connecting passage 10 from the first chamber 210 can be lowered, significantly to suppress the noise that produces in compressor or vibrations.
Preferably, pulsation reduces passage 21 length and sectional area and can regulate and correspond to flutter component and carry out ripple control, and therefore, pulsation reduces the length of passage 21 and sectional area suitably can regulate according to the frequency of control flutter component.
That is, the pulsation be formed in exhaust pulse reduction parts 20 reduces passage 21 and can have various shape, and such as spirality channel etc. regulate its length.
Fig. 7 shows the curve of the exhaust pulse between the present invention and comparative example.According to the present invention, curve shows the frequency band reducing the refrigeration agent measured when parts 20 are arranged in the connecting passage 10 be formed between the first chamber 210 and the second chamber 220 at exhaust pulse, but according to comparative example, curve shows the frequency band of the refrigeration agent measured when not having exhaust pulse to reduce parts 20.
As shown in Figure 7, be appreciated that the low frequency component in the frequency band between 100Hz and 300Hz can reduce by installing exhaust pulse reduction parts 20.
According to the present invention, exhaust pulse reduces in the connecting passage 10 of parts 20 between the first chamber 210 and the second chamber 220, but need not be confined to this.That is, as long as exhaust pulse reduces parts 20 and can reduce the vibrations and noise that produce in refrigerative circle system, any position can be arranged in.Such as, if there is sufficient space in the valve seat surface 213 of cylinder body 100, then exhaust pulse to reduce on passage 212 that parts 20 can be placed on the first chamber 210 of valve seat surface 213 and vent silencer 200 or in.
