Abstract
A sealed scroll compressor comprises a scroll compressor section, an electric motor, a sealed container, an oil storage, a fixed and orbiting scroll members, and a wire mesh member for improvement of oil separation in refrigerant gas. A shell portion of said sealed container is lined annularly with the wire mesh member and the gas containing oil is adapted to flow downwardly along the wire mesh member. When the gas flows downwardly, the oil sticks to the wire mesh member and is separated from the gas. The oil collected on the wire mesh member drops down into the oil storage. The gas from which the oil is separated is, after that, discharged out of the compressor.
