Abstract
An inlet port filter plate for attachment between a compressor inlet port and a suction hose assembly. The inlet port filter plate includes a main body and mounting surfaces for attachment between the compressor and the suction hose assembly or between the compressor and the compressor hose block. The main body defines a passage that allows for refrigerant flow through a filter which is positioned in the passage. The filter is adapted to stop debris in the refrigerant flow.
Claims13
An inlet port filter plate for attachment between at least one compressor inlet suction port and a suction hose assembly, the filter plate comprising:
- a main body comprising:
- a first side, said first side comprising a first connection opening, said first connection opening adapted to receive a compressor inlet port connector for attachment of the filter plate to compressor inlet port, said compressor inlet port connector having a compressor inlet port connector internal diameter;
- a second side, the second side comprising a second connection opening, said second connection opening adapted to receive a suction hose assembly connector for attachment of the filter plate to the suction hose assembly, said suction hose assembly connector having an suction hose assembly connector internal diameter;
- a first passage, said first passage adapted to allow a refrigerant flow between said second connection opening and said first connection opening, said first passage comprising a filter receiving section and a outflow section, said filter receiving section having at least one filter receiving section diameter and said outflow section having a outflow section diameter, wherein each said at least one receiving section diameter is greater than said outlet flow section diameter, and wherein said filter receiving section further comprises a filter receiving area for receiving a filter;
- and
- a filter, said filter comprising a mesh portion and an engagement portion, said engagement portion receiving and retaining said mesh portion, said engagement portion defining a filter outer diameter and said mesh portion defining a filter inner diameter, said filter positioned across said filter receiving section of said first passage, and said engagement portion received and retained within said filter receiving area,
- wherein, said outlet flow section diameter is at least as great as said compressor inlet port connector internal diameter,
- wherein, said filter outer diameter is greater than said outlet flow section diameter,
- wherein said filter outer diameter is greater than said suction hose assembly connector internal diameter, and
- wherein, said filter inner diameter is maximized such that refrigerant flow restriction caused by said filter is minimized.
An inlet port filter plate for attachment between at least one compressor inlet suction port and a suction hose assembly, the filter plate comprising:
- a main body defining a first passage, a first side, and a second side, the first and second sides positioned in a non-parallel relationship;
- the first passage adapted to allow a refrigerant flow between the first and the second side;
- the first side adapted to sealably connect to the at least one compressor inlet suction port;
- the second side adapted to sealably connect to the suction hose assembly;
- and
- a filter positioned across the first passage, the filter adapted to stop debris in the refrigerant flow.
