Abstract (en)
[origin: WO2010138510A2] A compressor (20), as well as a lightweight and strong casting (22) for a compressor (20), are disclosed. The compressor (20), which may be a reciprocating compressor (20) for use in compressing high-pressure refrigerants such as CO2, includes substantially reduced wall thicknesses (t) compared to prior art castings. The side walls (60, 62) of the compressor (20) can be manufactured to such reduced thicknesses (t) through the use of a bridge (70) spanning across the crankcase (34). This not only allows the opposing side walls (60, 62) to be manufactured of a thinner material, but the bottom cover (66) removably mounted to the crankcase (34) can be manufactured from a thinner and lighter material as well. Through the use of such a bridge (70), the resulting compressor (20) is not only able to satisfy current strength requirements, but at significant weight, size and cost savings as well.
