Abstract:
1. A scroll compressor comprising: a first scroll member having a base and a generally spiral wrap extending from said base; a second scroll member having a base and a generally spiral wrap extending from its base, said spiral wraps of said first and second scroll members interfitting to define compression chambers; a driveshaft and a motor for rotating said driveshaft, said driveshaft having an eccentric pin extending from one end of said driveshaft; said second scroll member being caused to orbit by said eccentric pin, and said second scroll member having a boss extending in an opposed direction from said base compared to said spiral wrap, said boss including an opening receiving a slider block and said eccentric pin with said slider block being intermediate said eccentric pin and said boss, and said boss having an upper surface defining a rear surface of said base of said second scroll member; stop structure on said eccentric pin for selectively contacting a stop surface on said slider block and preventing movement of said slider block toward said rear surface, said stop structure on said eccentric pin being spaced toward said second scroll member relative to said stop surface on said slider block, and said stop structure being out of contact with said stop surface in most cases; and said slider block being positioned vertically beneath said stop structure on said eccentric pin such that said slider block will fall vertically out of contact with said stop surface.
