ABSTRACT:
The disclosure describes a scroll compressor which incorporates a spring biased floating seal to facilitate the start-up for the compressor. The spring biased floating seal opens a discharge to suction leakage path before and during start-up for the compressor. After a few revolutions of the scrolls of the compressor the floating seal is biased against the load of the spring to close the leakage path due to pressurized working fluid of the compressor working against the biasing of the springs.
