Abstract:
1. An orientation and gravity insensitive oil management system integrated into the casing of a fluid displacement device, comprising: a) an oil dam housed in a casing of a fluid displacement device, said oil dam defining: i) an oil reservoir space between the casing of a fluid displacement device and one side of the oil dam, said oil reservoir space comprising a compressor pump part, and ii) an oil separation space between the casing and the other side of the oil dam; b) at least one oil separator and at least one oil pump forming at least one integrated unit, said at least one integrated oil separator/oil pump unit being capable of creating a pressure differential in the oil and pumping the oil from the oil separation space to the oil reservoir space, and being configured for operation with a drive mechanism of the fluid displacement device and being located in the oil separation space; c) at least one oil collection manifold being located in the oil separation space; d) one or more separated oil return paths being located in the oil dam; and e) one or more oil lubrication paths of the fluid displacement device being located in the oil reservoir space, said components a)-e) being in communication and forming a pressurized loop, and said oil management system in entirety being incorporated inside the casing of the fluid displacement device without affecting the size of said casing.
