Definitions

  • the present invention relates to a compressor, and more particularly to an oil separator for a compressor adapted to separate lubricating oil from a gaseous medium.
  • Compressors used in refrigeration and air conditioning systems such as swashplate type compressors and scroll compressors, for example, typically include a lubricating oil mist suspended in a gaseous refrigerant medium.
  • Such compressors are often employed in automotive air conditioning systems.
  • the oil-refrigerant mixture enters the compressor through a suction port and is compressed therein.
  • the compressed, high pressure oil-refrigerant mixture exits the compressor through a discharge port to travel through a refrigeration circuit before returning to the suction port to begin another cycle through the compressor and the refrigeration circuit.
  • Oil that remains suspended in the refrigerant as it travels throughout the refrigeration circuit can reduce the performance of the refrigeration circuit.
  • oil that travels through a heat exchanger in the refrigeration circuit is known to wet internal surfaces of the heat exchanger. Oil disposed on the internal surfaces of the heat exchanger reduces the heat transfer rate between the heat exchanger an the refrigerant. Accordingly, the compressor and other components of the refrigeration or the air conditioning system must have additional capacity to overcome the reduced heat transfer rate caused by oil flowing throughout the refrigeration circuit.
  • oil that remains suspended in the refrigerant flowing through the refrigeration circuit is not available to lubricate the moving parts of the compressor.
  • the compressor is susceptible to increased wear and seizure potential as a result of the reduced amount of available lubricating oil.
  • an oil separator can be added to the compressor.
  • Such an oil separator is typically positioned between the discharge port and a condenser inlet.
  • the oil separator functions to separate the suspended oil from the gaseous refrigerant and militate against the oil from exiting the compressor and circulating through the refrigeration circuit.
  • prior art oil separators such as U.S. Pat. No. 6,551,072 to Ota et al. and U.S. Pat. No. 7,281,913 to Oiwake typically increase the overall size of the compressor, limit the available positions for mounting the compressor, and do not significantly reduce the amount of oil required to adequately lubricate the compressor.
  • an oil separator for a fluid compressor wherein a space requirement is minimized, and an oil separation efficiency and available mounting positions of the compressor are maximized, has surprisingly been discovered.
  • an oil separator for a fluid compressor comprises a housing having a cavity formed therein; a wall disposed in the cavity to divide the cavity into an inlet side and an outlet side, the inlet side including a fluid inlet channel and at least one fluid drain channel, and the outlet side including a fluid outlet channel, wherein the inlet side of the cavity facilitates the separation of an oil from a fluid; and a conduit extending through the wall providing a fluid communication path between the inlet side and the outlet side of the cavity.
  • a fluid compressor comprises a housing having a discharge port and at least one oil reservoir formed therein; a generally cylindrical cavity formed in the housing forming an oil separator, the oil separator further comprising: a wall disposed in the cavity to divide the cavity into an inlet side and an outlet side, the inlet side including a fluid inlet channel providing fluid communication between the discharge port and the inlet side, and at least one fluid drain channel providing fluid communication between the at least one oil reservoir and the inlet side, the outlet side including a fluid outlet channel adapted to provide fluid communication between the outlet side and a refrigeration circuit, wherein the inlet side of the cavity facilitates the separation of an oil from a fluid; and a conduit extending through the wall providing a fluid communication path between the inlet side and the outlet side of the cavity.
  • a method for separating a lubricant from a refrigerant in a fluid compressor comprising the steps providing a housing for the compressor having a generally cylindrical cavity, a discharge port, and at least one oil reservoir formed therein; providing a wall to divide the cavity into an inlet side and an outlet side, the inlet side including a fluid inlet channel providing fluid communication between the discharge port and the inlet side of the cavity, and at least one fluid drain channel providing fluid communication between the at least one oil reservoir and the inlet side of the cavity, the outlet side including a fluid outlet channel providing fluid communication between the outlet side of the cavity and an associated refrigeration circuit; providing a conduit extending through the wall providing a fluid communication path between the inlet side and the outlet side of the cavity; causing a refrigerant-oil fluid mixture to flow from the discharge port, through the fluid inlet channel, and into the inlet side of the cavity, wherein the fluid inlet channel is formed to facilitate a rotational flow of the refrigerant-oil fluid mixture in the cavity to apply a centrifug

Additionally, a distance between the opposite end 26 of the conduit 22 and the wall 16 can be any selected distance to achieve a desired expansion characteristic of the fluid flowing therethrough.
  • a bell mouth 28 can be formed on the one end 24 of the conduit 22 as illustrated in FIG. 5 .
  • the bell mouth 28 facilitates the flow of the fluid into the conduit 22 to minimizes frictional losses and an associated pressure drop in the fluid flowing therethrough, which maximizes an efficiency of the compressor 1 .
  • the bell mouth 28 causes the fluid to flow adjacent the interior surface forming the cavity 12 as the fluid flows past the bell mouth 28 prior to flowing into the conduit 22 .
