Embodiment Construction

[0032] refer to Figure 1 to Figure 4 , shows a one-piece scroll compressor 100 . Using a powder metal process according to the method described in PCT International Publication No. WO2010 / 135232 subsequently filed in US National Phase Application Serial No. 13 / 320,867 and published as US2012 / 0118104 (which is incorporated herein by reference in its entirety), Powder Metal Vortex The rotary compressor 100 may be fabricated from a single compact of powdered metal.

[0033]To be clear, in the present invention, powdered metal formulations can be used to separately fabricate one or more parts of a component or entire assembly. However, the details of the construction and process used to manufacture the scroll compressor should not be so limited to the exact listed construction and method. As such, the scroll compressors described below are intended to be illustrative, not limiting.

Abstract

A powder metal formulation includes a solid lubricant and is particularly useful for the production of powder metal scroll compressors.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 599,042, filed February 15, 2012, and US Provisional Patent Application No. 61 / 720,226, filed October 30, 2012. The disclosures of both applications in their entireties are incorporated herein by reference for all purposes. Background technique [0003] The present invention relates to powder metal formulations including solid lubricants, and in particular to powder metal components, such as scroll compressors, made using these powder metal formulations. [0004] Scroll compressors are typically used to compress gases or refrigerants. Two components are located in such scroll compressors so as to have staggered and complementary scroll portions. These scroll portions may be shaped as involutes, spirals or other similar curves. [0005] During operation of a scroll compressor, one of the scroll portions orbits relative to the other scroll por...
