Abstract
The present invention provides an oil diffuser in the suction line of a compressor. The oil diffuser provides an increased cross sectional area whereby the flow velocity is decreased and further provides non-aligned entering and discharge lines whereby inertial forces and gravitational forces acting on oil flowing into the diffuser tends to move the oil away from the circuitous path necessary for entering into the discharge line. The resulting separated oil can enter the discharge line via a small hole in the tube which only permits metered mounts of oil to be supplied to the suction of the compressor.
Claims4
An oil diffuser comprising:
- a horizontally extending casing including a body portion and first and second end portions which coact to define a chamber;
- said first and second end portions each having an opening in its lower portion;
- an inlet line sealingly secured in said opening in said first end portion and extending into said chamber essentially in alignment with said opening in said second end portion;
- an outlet line having a first portion sealingly secured in said opening of said second end portion and extending into said chamber essentially in alignment with said inlet line;
- said outlet line having a second portion facing said inlet line and extending upwardly above said inlet line and including an inlet in said second portion at a location above said inlet line;
- a metering opening formed in the bottom of said first portion of said outlet line at a point within said chamber whereby flow entering said chamber via said inlet line tends to impinge upon said second portion of said outlet line causing separation of oil contained in said flow entering said chamber with said separated oil collecting in said chamber and exiting said chamber in a metered fashion via said metering opening due to aspirating into flow passing through said outlet line.
