초록

An improved efficiency economizer system for compressors incorporates the use of a check valve blocking return flow into the economizer return line. The economizer return line communicates with an economizer port, which communicates with a compression chamber. Pressure in the compression chamber can vary during the operational cycle of the compressor. Thus, in the past, there has sometimes been backflow of refrigerant through the economizer injection port and into the return line. The present invention prevents this backflow. Most preferably, the inventi...
