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.

Abstract: A scroll compressor includes a first scroll member, a second scroll member, and an aerostatic thrust bearing. The aerostatic thrust bearing forms a layer of gas between the second scroll member and a fixed supporting member to support the second scroll member as the second scroll member rotates and/or orbits. Also disclosed is a method of supporting a rotating/orbiting scroll member in a scroll compressor. The method including supplying pressurized gas to an aerostatic thrust bearing such that a layer of gas is formed between the rotating/orbiting scroll member and a fixed supporting member.
