44 Cast-in offset fixed scroll intake opening US14754885 2015-06-30 US09890784B2 2018-02-13 Ronald J. Duppert
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.

57 Scroll fluid machine US12003481 2007-12-26 US20080159894A1 2008-07-03 Yoshiyuki Kanemoto
A gap between opposing wrap portions is narrowed to increase compression efficiency, and an amount of machining time is reduced to thereby increase productivity.A plurality of proximate portions 8 are formed, at spacings in a spiral direction, on an outer peripheral surface 3B of a wrap portion 3 of a fixed scroll 1. Flat surfaces 8A are used to connect adjacent proximate portions 8. Similarly, a plurality of proximate portions 14 are formed, at spacings in the spiral direction, on an outer peripheral surface 13B of a wrap portion 13 of an orbiting scroll 11. Flat surfaces 14A are used to connect adjacent proximate portions 14. In this way, the outer peripheral surfaces 3B and 13B of the wrap portions 3 and 13 can be formed in polyangular shapes, so as to reduce a gap between the wrap portions 3 and 13 and simplify the shapes. As a result, an amount of machining time can be reduced.
