A compressor comprises a housing having a hollow interior for communicating a fluid comprising a mixture of a gas and a lubricant therethrough. The hollow interior of the housing is divided into a low pressure side and a high pressure side. The low pressure side is disposed upstream of compression mechanism and the high pressure side is disposed downstream of the compression mechanism. A porous flow controller fluidly couples the high pressure side to the low pressure side. The porous flow controller is configured to meter a flow of the lubricant from the high pressure side to the low pressure side.
