ABSTRACT:
A low side scroll compressor is provided with a pivoted bistable check valve. In the open position the valve is out of the direct discharge from the scrolls but in close proximity to the discharge tube such that upon stopping the compressor the reverse flow from the system impinges upon the valve member causing it to close.
