ABSTRACT:
Each compressor in a circuit has an oil pump with excess capacity relative to lubrication requirements of the respective compressor. Excess capacity is diverted to a common line which connects to each of the compressors in the circuit through a float valve. Each float valve is operated responsive to the oil level in the associated compressor such that oil diverted as excess capacity is supplied to any compressor in the circuit short of oil.
