Abstract: A pressure equalization system is provided for starting a compressor while maintaining the condenser at a high pressure and includes a valve and a bleed port. The compressor has a compressor inlet for receiving a fluid at a first pressure and a compressor outlet for discharging the fluid at a second pressure. The valve is proximate to and in fluid communication with the outlet and is movable to an open position when the compressor is operating to permit the fluid at the second pressure to flow through the valve and is movable to a closed position when the compressor stops operating to prevent backflow of the fluid at the second pressure through the valve toward the inlet. The bleed port is upstream of the valve and in fluid communication with the inlet to equalize the pressure of the fluid contained in the compressor when the compressor stops operating.

Abstract: A pressure equalization system (10) is provided for starting a compressor (2, 302) while maintaining the condenser at a high pressure and includes a valve (214, 308) and a bleed port (484) or passageway (218). The compressor (2, 302) 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 (214, 308) is proximate to and in fluid communication with the compressor outlet (20) and is movable to an open position when the compressor (2, 302) is operating to permit the fluid at the second pressure to flow through the valve (214, 308) and is movable to a closed position when the compressor (2, 302) stops operating to prevent backflow of the fluid at the second pressure through the valve (214, 308) toward the compressor inlet (16). The bleed port (484) or passageway (218) is upstream of the valve (214, 308) and in fluid communication with the compressor inlet (16) to equalize the pressure of the fluid contained in the compressor (2, 302) when the compressor (2, 302) stops operating.
