Abstract
A compressor arrangement includes two or more compressors () arranged in a fluidly parallel configuration and a lubricant sump () containing a volume of lubricant operably connected to the two or more compressors. A lubricant sump pressure (P) is greater than a lubricant cavity pressure of each compressor (Pa, Pb, Pc) of the two or more compressors at all operating conditions of the two or more compressors. An equilibrium lubricant line () connects the lubricant sump to the two or more compressors to convey lubricant from the lubricant sump to a lubricant cavity () of each compressor of the two or more compressors.
