Abstract
A high side compressor system includes a compressor housing, motor, and a compression chamber. The compression chamber is disposed within the compressor housing. An accumulator is fluidly coupled to the compressor housing via a pressure-equalization tube. A pressure-equalization valve is disposed in the pressure-equalization tube. The pressure-equalization valve closes access to the pressure-equalization tube responsive to an electrical current being applied to the pressure-equalization valve. The pressure-equalization valve is electrically coupled to a compression mechanism such that interruption of electrical current to the compression mechanism interrupts electrical current to the pressure-equalization valve thereby opening the pressure-equalization valve.
