Abstract:
A scroll compressor comprising:a first scroll member having a base and a generally spiral wrap extending from its base; a second scroll member having a base and a generally spiral wrap extending from its base, said wraps of said first and second scroll members interfitting to define compression chambers; a drive shaft driven to rotate, and to cause said second scroll member to orbit, said drive shaft including an eccentric pin extending upwardly into a bore in a slider block, said slider block being received within a boss extending downwardly from said second scroll member such that said eccentric pin moves with rotation of said shaft to cause said second scroll member to orbit relative to said first scroll member; said eccentric pin and said slider block being engaged along an interface surface when rotation of said shaft is transmitted into orbiting movement of said second scroll member, and there being a port to deliver lubricant to said interface surface, said interface surface being designed to facilitate driving the lubricant from said port and along said interface surface, said interface surface being provided by a pair of generally flat surfaces; and said port extending through an entire width of said slider block from an inner peripheral surface defining said bore to an outer peripheral surface, and opening to a position circumferentially adjacent one end of said generally flat surface on said slider block.
