Abstract:
1. A method of providing a scroll compressor comprising the steps of: (1) providing an orbiting scroll and a non-orbiting scroll, with each of said orbiting and non-orbiting scrolls having a base and a generally spiral wrap extending from said base, and providing a crankcase for supporting said orbiting scroll, defining a back pressure chamber between said crankcase and said orbiting scroll; and (2) forming an opening through said base of said orbiting scroll from a compression chamber defined between said wraps of said orbiting and non-orbiting scroll, and said opening extending from said compression chamber to said back pressure chamber, said opening being formed to include a first tap portion extending from said compression chambers to a crossing tap portion, said crossing tan portion extending to a communicating tap portion, which communicates with said back pressure chamber, such that said crossing tap portion moves a location of the fluid from said first tap portion to a distinct location on said orbiting scroll relative to said communicating tap portion, and placing a restriction in said communicating tap portion.
