Samsung patents air conditioner part that recycles oil more efficiently
Samsung has filed a patent for a scroll compressor, a key component in air conditioners that compresses refrigerant gas. The design includes a specific hole and pressure adjustment system to return lubricating oil from the compressor back into the machine, ensuring it keeps running smoothly.
In the filing’s own words
A scroll compressor including a housing; a fixed scroll to be provided in the housing; an orbiting scroll to be engaged with the fixed scroll to form a compression chamber; an injection hole formed in the fixed scroll; a recovery flow path to allow oil recovered from an oil separator to flow toward the scroll compressor through the injection hole while the injection hole is connected with the oil separator; and a pressure-lowering apparatus to adjust the pressure of the oil recovered from the oil separator.
What exactly they claim (claim 1)
1. A scroll compressor, comprising: a housing; a fixed scroll to be provided inside of the housing; an orbiting scroll to be engaged with the fixed scroll to form a compression chamber; an injection hole formed at the fixed scroll; a recovery flow path to allow oil recovered from an oil separator to flow toward the scroll compressor through the injection hole while the injection hole is connected with the oil separator; and a pressure-lowering apparatus to adjust pressure of the oil that is recovered from the oil separator.
