Definitions
- the present invention relates to a compressor having a gas-bearing piston, in particular for use as a refrigerant compressor in a domestic refrigerator.
- Compressors with rotary-driven lifting pistons and oil lubrication are conventionally used in domestic appliances. Owing to the rotary drive, during the course of its lifting movement in a working chamber the piston in such a compressor is also exposed to forces transverse to the lifting direction which push the piston against the wall of the working chamber. To protect the compressor against frictional wear there must be a continuous film of oil between piston and chamber wall. The viscosity of the oil must be high enough to prevent the oil from being displaced between wall and piston under the influence of a transverse force. The greater the transverse forces are, the more viscous the oil must be and the friction losses are all the greater owing to the viscosity of the oil.
- a linear motor of this kind exerts smaller transverse forces on the piston so lower viscosity lubricants can be used, through to bearing of the piston by the gas that is itself to be compressed.
- openings are formed in a wall of the working chamber covered by the piston and communicate with an outlet connection of the compressor, so a small portion of the compressed medium can flow from the outlet connection, via the openings and back into the working chamber and in the process generates a gas cushion between piston and wall which ideally allows movement of the piston without any contact with the wall at all and therefore without any frictional wear either.
- a compressor comprising an inlet connection and an outlet connection for a gas to be compressed, and a working chamber in which a piston for compressing the gas can be displaced, openings communicating with the outlet connection being configured in a wall of the working chamber covered by the piston, said compressor being characterized by a particle filter arranged in a flow path of the gas through the compressor between the inlet connection and the outlet connection.
- the inventive particle filter remedies this by preventing these foreign bodies from reaching the wall openings.
- a particle filter of this kind may be provided at various sites in the compressor. According to a first configuration the particle filter is arranged between the inlet connection and the working chamber.
- a particle filter of this kind has the advantage that foreign bodies can be prevented from reaching the working chamber from the outset. This is particularly desirable in the case of coarse foreign bodies which can cause damage solely by virtue of their presence in the working chamber.
- the particle filter is arranged in a pipe, connecting an egress of the working chamber to the outlet connection, between the egress and a branch pipe leading to the openings.
- This arrangement of the filter does not lead to an undesirable increase in pressure at the inlet connection of the compressor.
- a greater drop in pressure can be built up at such a filter arranged on the pressure side of the compressor than at the inlet-side filter described above, so sufficient throughput can also be achieved in a compact filter although such a high drop in pressure does in turn affect the efficiency of the compressor.
- a branch pipe leading to the openings branches off from a pressure pipe connecting an egress of the working chamber to the outlet connection, and the particle filter is arranged in the branch pipe.
- the filter arranged in the branch pipe does not prevent foreign bodies from passing through the compressor from the start, it does collect them during the course of compressor operation as soon as they pass into the branch pipe.
- the branch pipe comprises a distribution chamber and a hole connecting the distribution chamber to the pressure pipe, the wall covered by the piston forming a partition between the working chamber and the distribution chamber.
- the particle filter can be small and compactly arranged in the hole, or it can be arranged in the distribution chamber so as to cover the partition.
- the distribution chamber is preferably a hollow cylinder that extends around the cylindrical working chamber.
- FIG. 1 shows a schematic section through a compressor according to the invention with suction-side particle filter
- FIG. 2 shows a section analogous to FIG. 1 through an inventive compressor with pressure-side particle filter
- FIG. 3 shows a section analogous to FIG. 1 through an inventive compressor with particle filter arranged in a branch pipe, and
- FIG. 4 shows a section through a modification of the compressor with particle filter arranged in a branch pipe.
- FIG. 1 shows a schematic section through a compressor according to a first embodiment of the invention.
- the compressor is part of a refrigerating machine of a domestic refrigerator which is not shown as its remaining components are known.
- a piston 2 can be reciprocated by a driving unit, likewise known per se and not shown, in a cylindrical working chamber 1 of the compressor.
- the driving unit can for example be a linear motor as described for instance in DE 10 2004 010 849 AG, but in general any desired driving unit which is capable of generating a driving force, and whose transverse components are small enough that frictional contact between the walls of the working chamber 1 and the piston 2 can be reliably avoided, may be considered.
- a suction valve 3 and a pressure valve 4 which connect the working chamber 1 to a suction pipe 5 and a pressure pipe 6 respectively and via these to an inlet connection 12 and an outlet connection 13 respectively are located at one end face of the working chamber.
- a particle filter 7 is provided in the suction pipe 5 .
- a hole 8 leads from the pressure pipe 6 to a distribution chamber 9 with a hollow cylindrical shape and which surrounds the working chamber 1 , so the wall 10 of the working chamber 1 covered by the piston 2 as it moves is a partition between the working chamber 1 and the distribution chamber 9 . A large number of narrow openings 11 is distributed in this wall 10 .
- the piston 2 when moved to the right, sucks in refrigerant from the inlet connection 12 via the suction pipe 5 , the particle filter 7 and the suction valve 3 into the working chamber 1 .
- the contents of the working chamber 1 are firstly compressed at the pressure prevailing in the pressure pipe 6 before the pressure valve 4 opens and the compressed gas runs off into the pressure pipe 6 .
- a small portion of the gas flowing in the pressure pipe 6 passes through the hole 8 and into the distribution chamber 9 and from there via the openings 11 in the wall 10 back into the working chamber 1 where it forms a gas cushion between the piston 2 and the wall 10 .
- the embodiment shown in FIG. 2 differs from that in FIG. 1 in that the particle filter 7 is arranged in the pressure pipe 6 , between the pressure valve 4 and the hole 8 , and not in the suction pipe 5 . As in the embodiment of FIG. 1 all of the refrigerant passing through the compressor passes through the particle filter 7 . Owing to the arrangement of the particle filter 7 in the pressure pipe 6 a greater drop in pressure can be built up at the particle filter 7 than in the case of the embodiment of FIG. 1 , so sufficient throughput can be achieved even with a compact filter.
- FIG. 3 differs from the two described above in the placement of the particle filter 7 in the distribution chamber 9 .
- the particle filter 7 rests on the wall 10 , so it is pressed against the wall 10 as a result of the pressure difference between its outer and inner sides.
- the increased demand for power owing to filtering is only a fraction of the increased demand of the first two embodiments.
- the provision of the particle filter 7 in the distribution chamber 9 has the advantage that refrigerant can flow through the particle filter 7 over a very large cross-sectional area, so even when using a very porous filter a throughput sufficient to maintain the gas cushion can be attained.
- the particle filter 7 preferably has a layered structure here with a fine-pored outer layer 7 a and a coarse-pored, easily permeable inner layer whose function is substantially to maintain a spacing between the fine-pored layer 7 a and the wall 10 in which the gas can uniformly distribute itself among the openings 11 .
- FIG. 4 shows the currently preferred embodiment of the invention. This embodiment differs from those described above in that the hole 8 , which connects the distribution chamber 9 to the pressure pipe 6 , is long enough and wide enough to receive the particle filter 7 in the form of a filter cartridge 14 .
- the filter cartridge is introduced into the hole 8 from its end that faces the pressure pipe 6 .
- a pressure-side flange 15 of the filter cartridge rests on a shoulder 16 formed at the entrance to the hole 8 , so the filter cartridge 14 is pressed against the shoulder 16 by the drop in pressure which it generates on the refrigerant flowing through.
- the suction-side particle filter 7 from the embodiment of FIG. 1 can also be combined with the particle filter according to FIG. 3 or 4 that is arranged on the route of the refrigerant from the pressure pipe 6 to the openings 11 .
- the suction-side particle filter can be a coarse-pored filter with low flow resistance which is used solely to keep coarse contaminants away from the working chamber 1 while finer contaminants are caught by the pressure-side particle filter.
