Abstract
A thermally responsive valve assembly for scroll motor-compressor high temperature protection, which causes a high-side to low-side leak when excessive discharge gas temperatures are encountered, thereby causing the motor protector to trip and de-energize the motor. The valve assembly includes means for ducting the excessive temperature discharge gas to the lower portion of the motor/compressor shell to the motor to circulate the high temperature gas throughout the motor cavity. The excessive temperature discharge gas heats the motor stator and windings which will in turn cause the motor protector to trip and de-energize the motor. A secondary flow passage increases the flow rate or the discharge gas to lower the cycle time of the compressor.
