  • Scroll compressor with improved tip seal
    Patent number: 6074185
    Abstract: A scroll wall tip seal of novel shape allows the scroll wall to be machined with a single, larger concave transition corner radius, where the flank of the scroll wall blends into the scroll base plate. The tip seal covers the entire surface area of the terminal edge of the scroll wall, and has convex radiused sides that match the single radius of the scroll wall's concave transition corner. This allows the scroll wall to be machined with a single tool, all the way round, in a single pass.
