Abstract
A scroll compressor has a fixed scroll and an orbiting scroll nested with one another within a shell. A hub extends axially from a lower surface of the orbiting scroll with a central bore formed therein. A crankshaft, having an eccentric pin extending axially from one end thereof, is drivable by a motor. A passageway for the delivery of a lubricant extends through the crankshaft and the eccentric pin. A slider block is received by the central bore, and a pin bore, which extends axially through the slider block, receives the eccentric pin. An axially extending projection maintains a gap between the slider block and the orbiting scroll which enhances the flow of lubricant to bearing surfaces of the scroll compressor.
