ABSTRACT:
A scroll compressor assembly includes a shaft having an eccentric pin that orbits a first scroll member relative to a second scroll member. The eccentric pin has a length extending from a base end to a distal end, which defines a contact area having a slight crown that engages a slider block. The contact area is moved toward the distal end of the eccentric pin to improve the stability of at least one of the first and second scroll members.
