摘要： A pressure equalisation method and system (10) is provided for starting a compressor (2) while maintaining the compressor (2) at a high pressure and comprises a valve (28) and a bleed port (26). The compressor (2) has a compressor inlet (16) for receiving a fluid at a first pressure and a compressor outlet (20) for discharging the fluid at a second pressure, and is operable to compress the fluid from the first pressure to the second pressure. The valve (28) is proximate to and in fluid communication with the compressor outlet (209 and is movable to an open position when the compressor (2) is operating to allow the fluid at the second pressure to flow through the valve (28) and is movable to a closed position when the compressor (2) stops operating to prevent backflow of the fluid at the second pressure through the valve (28) toward the compressor inlet (16). The bleed port (26) is upstream of the valve (28) and in fluid communication with the compressor inlet (16) to equalise the pressure of the fluid contained in the compressor (2) when the compressor (2) stops operating.
