ABSTRACT:
A control valve configuration for a compressor system comprises a compressor receiving gas and liquid lubricant for compression and delivery to a separator where the compressed gas is separated from the liquid and passed to an end use with the liquid being recycled to through the compressor. The control valve configuration is arranged to control flow through the gas inlet to the compressor in response to demands of the compressor system and mechanisms are provided to supply pressurized gas to the inlet zone of the compressor upon the valve configuration moving towards a position preventing flow of gas to the compressor to thereby reduce vacuum conditions in the inlet zone thereby reducing transient noises associated with compressor operation and minimizing power consumption during no load operation.
