Abstract
A tip seal for scroll type compressors is provided to seal the tips of the scroll wraps of the stationary and orbiting scrolls. The seal consists of a 'C' shaped cross sectional spring formed to fit in a slot in the tip of the scroll wraps. The spring is coated with a Teflon based material to seal the scroll tip from the high pressure side to the low pressure side and the center of the 'C' shaped cross sectional spring is filled with an O-ring type neoprene material extending through at least part of the length of the spring to seal the core of the spring against leakage of fluid being compressed.
