US Patent 7060122 Oil separator for a compressor

An oil separator for a compressor includes a wall with an inner surface defining an inner chamber. The inner chamber includes an oil accumulation region and a separator region with an impingement surface. A mixture inlet provides a passageway for an oil and gaseous refrigerant mixture to flow from the exterior of the separator into the inner chamber. Oil is separated from the mixture as the mixture impinges against the impingement surface. The separated oil drains into the accumulation region and exits the separator through the oil outlet. A gas outlet provides a passageway for the gaseous refrigerant from the separator region and out of the separator.
