Scroll compressor with lubrication directed to drive flat surfaces

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 opening to a position circumferentially adjacent said interface surface to deliver lubricant to said interface surface, said interface surface being designed to facilitate driving the lubricant along said interface surface;
• said interface between said eccentric pin and said slider block being provided by a pair of generally flat surfaces;
• and
• said slider block extends further from said second scroll member than docs said boss, and an end of said slider block remote from said second scroll member, and extending beyond said boss, includes said port.

• said interface between said eccentric pin and said slider block being provided by a pair of generally flat surfaces;
• and
• said eccentric pin is constructed such that the entirety of said interface surface is defined on one side of an extension of a center line of said drive shaft drawn perpendicular to said generally flat surface of said eccentric pin.

• a second scroll member having a base in 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 slider block and said second scroll member to orbit relative to said first scroll member, and
• 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 provided by a pair of generally flat surfaces, with one of said generally flat surfaces being provided with a chamfer adjacent an outlet side of said port.
