Patent ID: 7476092

Claim:
A scroll compressor comprising: a first scroll member having a base and a generally spiral wrap extending from the base; a second scroll member having a base and generally spiral wrap extending from its base, said spiral wraps of said first and second scroll members interfitting to define compression chambers; said second scroll member having a boss extending from the base in an opposed direction relative to the generally spiral wrap, a driveshaft being driven to rotate by a motor about an axis, and said driveshaft having an eccentric pin extending upwardly into said boss, and a slider block positioned between said eccentric pin and said boss; and said eccentric pin and said slider block each having a generally flat surface in contact with each other to cause rotational movement of said rotating shaft to be transmitted to said second scroll member through said slider block, and said flat surface on said slider block being formed to extend radially inwardly at an angle that is non-parallel to said axis, and along a direction moving away from said base of said second scroll member, said generally flat surfaces on said eccentric pin and said slider block having a resultant force on said slider block urging said slider block away from said second scroll member due to said flat surface on said slider block being formed to extend radially inwardly along said angle.
