Fig. 2 illustrates the second line map structure,
Fig. 3 illustrates the tertiary circuit graph structure,
Fig. 4 illustrates the 4th line map structure,

The specific embodiment
In Fig. 1, schematically illustrate compressor of air conditioner 1, foul particulate filter 3 and foul particle separator 5.These three elements are positioned at the compressor of air conditioner enclosure interior, and this air conditioner compressed engine housing 7 illustrates by a dotted line.Foul particle separator 5 is according to cyclone separator principle work, wherein, on the wall of separator 5 the foul particle separation gone out and is collected in the foul particle collection device 9 by centrifugal force.The cold-producing medium circulation piping 11 of having broken away from the foul particle continues to flow to foul particulate filter 3.In foul particulate filter 3 back, jockey 13 is guided the suction district 15 of compressor 1 into, and wherein, drive chamber's pressure is led back 17 and fed in the jockey 13, and this drive chamber's pressure is led back and drawn self-driven chamber pressure district 19.This class drive chamber pressure is led back in the adjustable compression machine to be known and need not further to explain at this.Importantly foul particle separator 5 is in the layout of the equipment that is used for the separate dirt particle for the present invention, and these foul particles can be collected in the collecting chamber 9 and therefore can not arrive the filter 3 that connects later.In filter 3, can not form the filter cake that obviously works thus, this filter cake otherwise can fall along with running time progress produces gradually increased pressure, the efficient of equipment falls and impairs in this pressure.The device of compressor itself and filter 3 that illustrates previously and foul particle separator 5 is connected with the suction district 21 or the higher-pressure region 23 of air-conditioning equipment in the outlet of housing 7.
Line map among Fig. 2 is compared difference and be that different drive chamber's pressure is led back 25 and is connected between filter 3 and the foul particle separator 5 in swabbing pressure district duct section 27 with the line map among Fig. 1.This causes, and lead back 25 foul particle from drive chamber's pressure and under any circumstance pass through filter 3 now, and additional from the main suction streams in zone 21 through foul particle separator 5.That is, the inner foul particle that produces of drive chamber under any circumstance intercepted and captured by filter 3 and directly delivery give the suction district 15 of compressor of air conditioner 1, as shown in fig. 1.
Line map among Fig. 3 is compared difference and is with the line map among Fig. 1 and 2, different drive chamber's pressure is led back 29 and is connected with duct section 31 in the suction district 21, make this drive chamber's pressure lead back 29 also necessary process foul particle separators 5, thereby make the filter 3 that is connected the back also needn't receive the foul particle again, it is lower better with equipment efficient during running time that this causes pressure to fall.
In another line map in Fig. 4, foul particle separator 5 is in an externally-arranged duct section 33 at air-conditioning equipment of air conditioner compressed engine housing 7.Therefore foul particle separator 5 can be arranged on the equipment position separately like this, makes it irrespectively to touch well with the infield of compressor of air conditioner and can correspondingly manage collection container 9 thus.Lead back 17 at this drive chamber's pressure and also also carry out to the suction district 15 of compressor 1 thus to jockey 13, as having illustrated among Fig. 1 in compressor housing 7 inside.
All be placed in air conditioner compressed engine housing 7 outsides at Fig. 5 apoplexy involving the solid organs composition granule separator 5 and foul particulate filter 3.Additional thus that provide foul particulate filter 3 and the irrelevant layout in compressor of air conditioner infield.Therefore but thereby drive chamber's pressure is led back 17 and must also directly be carried out in the suction district 15 of compressor of air conditioner to jockey 13 in air conditioner compressed engine housing 7 inside.
Be again that only foul particle separator 5 is placed in compressor housing 7 outsides in Fig. 6.Because filter 3 is placed in compressor housing 7 inside again, thus drive chamber's pressure lead back 25 again can be as having illustrated among Fig. 2, in jockey 27, carrying out and through filter 3, feasiblely can in filter 3, be intercepted and captured from the foul particle of drive chamber.
Principle of the present invention is, introduces additional foul particle separator 5 and is used for separating particles, and these particles are collected in the collecting chamber 9 and therefore can arrive the filter 3 that is connected the back.In filter 3, do not form the filter cake that obviously can arouse attention thus, this filter cake otherwise can fall along with running time progress produces gradually increased pressure, the efficient of equipment falls and impairs in this pressure.
Another purpose of the present invention is that drive chamber's discharge currents 25 or 29 is connected on the suction district 15 of compressor 1 by this way, and make can for example not influence the compressor control characteristic owing to the pressure on the filter 3 falls to increase with violating original idea.This especially can be by leading return realization through the jockey 29 among Fig. 3 in foul particle separator 5 fronts with drive chamber's discharge currents.This task for example can not realize by foul separator on the machine exit side and sieve.
