| A fixed scroll compressor body includes a scroll compressor body casting. The casting has a central body portion having a plate-like base with a spiral scroll rib projecting from the base at a right angle thereto. The spiral scroll rib includes a volume between the spiraled ribs for the compressing of refrigerant. The spiral scroll rib spirals from a central region of the plate-like base to an outer wall of the central body portion. The casting further includes a first inward-protruding portion that protrudes from the outer wall into the volume. A distance that the first inward-protruding portion protrudes into the volume is greater than a thickness of the first inward-protruding portion such that removal of the first inward-protruding portion results in a first intake opening in the outer wall. The first intake opening provides a path for a flow of refrigerant into the volume. | ||||||

| 140 | Variable flank relief for scroll wraps | EP99310252.4 | 1999-12-20 | EP1024288A1 | 2000-08-02 | Bush, James W |
A scroll compressor having a non-uniform generating radius for its scroll wraps is formed to have a flank relief which is greatest at locations having the highest generating radius. In scroll compressors having non-uniform generating radii, there is an increased likelihood of contact at the areas (A,B,C,B') having the highest generating radius. Thus, flank relief is provided at the areas having the higher generating radii. In addition, the flank relief is preferably proportional to the generating radius. Further at areas having a generating radius below a predetermined minimum, no flank relief is necessary. |
