HIGH TO LOW SIDE BYPASS TO PREVENT REVERSE ROTATION

摘要

Rotary compressors (12) such as screw compressors and scroll compressors are capable of reverse operation at shutdown as the system pressure seeks to equalize through the running gear. The present invention provides a valved bypass (22) which is opened responsive to the initiation of stopping the compressor (12). The valved bypass (22) may be located internally or externally with respect to the compressor (12).
