摘要： A pressure equalization method and 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, and is operable to compress the fluid from the first pressure to the second pressure. The valve is proximate to and in fluid communication with the compressor 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 compressor inlet. The bleed port is upstream of the valve and in fluid communication with the compressor inlet to equalize the pressure of the fluid contained in the compressor when the compressor stops operating.

摘要： A hermetic compressor unit housing comprised of a shell having a top section and a bottom section which receives the top section, the shell being formed of sheet metal and having generally cylindrical sidewalls wherein the sidewall taken in a generally axial direction is substantially straight, each shell section having an opening, a substantially cylindrical portion, and a closed end portion, the opening having a substantially circular horizontal cross-sectional geometry defined by a major axis and a minor axis, the horizontal cross-sectional geometry including substantially liner opposing sidewall portions preferably disposed adjacent to the intersection of the horizontal sectional geometry with the minor axis, and methods of aligning the shell sections for installation of fixtures and mating of the shell sections.
