Abstract: A scroll compressor includes scroll members that are made of austempered grey iron in whole or in part. The austempering process can increases fatigue strength and toughness of a grey iron while maintaining its good machinability and vibration damping characteristics. Use of austempered grey iron scroll members allows the scroll compressor to improve its capacity, efficiency, and durability.

Abstract: A crankshaft assembly for a scroll compressor is disclosed. The crankshaft assembly includes a crankpin having a plurality of apertures therethrough. A crankshaft body has an aperture therethrough. The aperture of the crankshaft and one of the plurality of apertures of the crankpin being aligned when in an assembled state such that in operation fluid flows between the aperture of the crankshaft body and the one of the plurality of apertures of the crankpin. The crankshaft body includes a second aperture aligned with a second of the plurality of apertures of the crankpin. The crankpin and the crankshaft body are separate members. A fastener extends through the second of the plurality of apertures of the crankpin and into the second aperture of the crankshaft body to secure the crankpin and the crankshaft body together in the assembled state.
