As shown in Fig. 1 to Fig. 4, fixing suction pipe 103 on the seal container 101, suction pipe 103 has the open part 102 of opening mouth at seal container 101.In addition, also be equipped with in the seal container 101 by motor 104 compressor driven structure 105 in addition, and be filled with refrigerant 106.
Be provided with in the compressing mechanism 105: the reciprocating therein cylinder 108 of piston 107, be arranged on the open end of cylinder 108 and have with cylinder 108 in the valve plate 110 and the absorbing silencer 111 of the inlet hole 109 that is connected.
Be provided with the silence space 114 that forms by resin in the absorbing silencer 111, silence space 114 is surrounded by seal container side side 112 and side 113 (see figure 4)s relative with the seal container side etc., is provided with in addition to make the exit portion 115 that silence space 114 is connected with inlet hole 109 and make the suction 116 of silence space 114 at seal container 101 inner openings.
Below operational circumstances in the compressor with above-mentioned formation and effect are described.
During operation, compressing mechanism 105 is driven by motor 104, piston 107 is reciprocating in cylinder 108, and the refrigerant 106 that flows into from freezing loop (not shown) flow in the seal container 101 from the open part 102 of suction pipe 103, and spreads in seal container 101.Afterwards, refrigerant 106 is from sucking
116 are sucked in the absorbing silencer 111, pass silence space 114, flow in the cylinder 108 by inlet hole 109 from exit portion 115 again, are compressed by piston 107 in cylinder 108, and then are discharged in the freezing loop (not shown).
Here, because open part 102 is positioned adjacent to seal container side side 112 in the absorbing silencer 111, and is with it configuration state, therefore, flow into the seal container side side 112 that the refrigerant 106 in the seal container 101 can at first be run into absorbing silencer 111 from the open part 102 of suction pipe 103, in seal container 101, spread then.
In the ordinary course of things, the temperature of the refrigerant 106 that returns from freezing loop (not shown) is near outer temperature degree, and temperature is lower comparatively speaking, begin to be cooled from seal container side side 112 so absorbing silencer 111 is understood.In addition, the refrigerant 106 of diffusion in seal container 101 can be by motor 104 and compressing mechanism 105 heating, and temperature can rise.After refrigerant 106 that temperature has uprised was inhaled in the absorbing silencer 111 from suction port 116, refrigerant 106 can (under the effect of the refrigerant that is returning) obtain cooling in that absorbing silencer 111 is inner, and its temperature will descend again.
The temperature variation of these refrigerant 106 is described below by Fig. 5.Among Fig. 5, the longitudinal axis is the temperature of refrigerant 106, and transverse axis is represented along the measuring point for the temperature of the refrigerant 106 of the path setting of refrigerant 106.Below, the temperature distribution in present embodiment and the existing apparatus is done one relatively.
Each measuring point position in the present embodiment shown in Fig. 5 is: the A point is near open part 102, and the B point is near suction port 116, and the C point is in absorbing silencer 111 inside, and the D point is near the exit portion 115 that is about to be drawn in the cylinder 108.In addition, the each point position in the existing apparatus be in [background technique] part in the existing closed compressor described with present embodiment in the corresponding position of each point.
As shown in Figure 5, near the open part 102 that is on the point of the A shown in Fig. 4, the temperature of the refrigerant 106 in present embodiment and the existing apparatus is consistent mutually.On the other hand, on the point of the B shown in Fig. 3, the temperature of the refrigerant 106 in the present embodiment wants high a lot of compared with existing apparatus.This is because in existing apparatus, be directly to suck refrigerant on A point, and suction in the present embodiment is the refrigerant 106 that has spread, has been heated in seal container 101.
But the temperature of the refrigerant 106 in the present embodiment on the C point will be lower than the temperature that B is ordered.This is because under the effect of the refrigerant 106 that returns from freezing loop (not shown), absorbing silencer 111 is begun to cool down from seal container side side 112, thereby makes the refrigerant 106 in the absorbing silencer 111 obtain cooling.
As a result, can make to be about to be inhaled near temperature in cylinder 108, that the exit portion 115 be the refrigerant 106 at D point place and to be reduced to compared with existing apparatus to come on the high slightly temperature, thereby the refrigerant 106 of low temperature can be provided in cylinder 108.Like this, can compress highdensity refrigerant 106, freezing performance very big decline can not occur, therefore can keep very high efficient.
In addition, the temperature of the refrigerant 106 during owing to compression is lower, and therefore refrigerant 106 temperature after the compression also can keep lower, thereby can suppress the decomposition of refrigerant 106 and refrigeration oil, keep very high reliability.
On the other hand, have at open part 102 under the occasion of liquid refrigerant and cold oil inflow from suction pipe 103, seal container side side 112 in these liquid refrigerants and cold oil meeting elder generation and the absorbing silencer 111 bumps, and drops to then in the seal container 101.Here, because suction port 116 is located on the position away from the seal container side side 112 of absorbing silencer 111, and be positioned at suction pipe 103 tops, court and the contiguous rightabout side opening of seal container 101 walls, therefore, liquid refrigerant and cold oil can directly be sucked from suction port 116 hardly.
And, even on the seal container side side 112 of absorbing silencer 111, adhering under the cooling oil condition, because suction port 116 is located on the position away from the seal container side side 112 of absorbing silencer 111, therefore, such cold oil also can be inhaled into hardly.
Its result can avoid compressing the fault of the compressing mechanism 105 that causes because of liquid refrigerant and cold oil that 107 pairs in piston is drawn in the cylinder 108, thereby a kind of closed compressor of high reliability can be provided.

Because open part 102 is positioned adjacent to the waveform part 219 on the seal container side side 112 that is formed on absorbing silencer 111 and is configuration state, therefore, flow into the waveform part 219 that the refrigerant 106 in the seal container 101 can be run into absorbing silencer 111 earlier from the open part 102 of suction pipe 103, in sunk part 218, stop, and then diffuse in the seal container 101.
On the seal container side side 112 of absorbing silencer 111, form after sunk part 218 and the waveform part 219, compare with the plane, surface area will increase, and therefore, the area of the seal container side side 112 that the cryogenic coolant that is flowed in the absorbing silencer 111 is cooled off also will increase.Like this, the area that is cooled off by refrigerant 106 can increase.In addition, by the refrigerant 106 in open part 102 flow into seal container 101 is stopped sunk part 218, make the cryogenic coolant 106 that flows into from suction pipe 103 be difficult for spreading, thereby can make seal container side side 112 keep low-temperature condition.
In addition, because absorbing silencer 111 is made by the low resin of pyroconductivity, just be difficult to import into wherein from the motor 104 that constitutes thermal source and the heat of compressing mechanism 105.Like this, the refrigerant 106 in the absorbing silencer 111 just is difficult for being heated.Simultaneously, because the thickness that the seal container side side 112 of stop takes place cryogenic coolant 106 waits other side thin than the side 113 relative with the seal container side, carry out heat exchange easily, therefore can make the refrigerant in silence space 114, the refrigerant circuits 217 obtain cooling.
In addition, the refrigerant circuits 217 that is flow through owing to the refrigerant 106 that supply in the cylinder 108 is formed on the inner side surface of seal container side side 112, and also contain waveform part 219, therefore, the temperature of the refrigerant 106 in the refrigerant circuits 217 is descended.
Like this, just can in cylinder 108, provide the refrigerant 106 of low temperature, can compress the high refrigerant of density, thereby freezing performance can not descended, keep very high efficient simultaneously again.In addition,, can make the refrigerant after the compression also keep very low temperature, thereby can suppress the decomposition of refrigerant and cold oil, keep very high reliability because the refrigerant temperature before the compression is low.
