ROTARY COMPRESSOR HOUSING

摘要

A rotary compressor housing is outwardly formed with reinforcing grids in the form of square, diaper or honeycomb. The reinforcing grids allow the intermediate wall portions between the bolted wall portions to thermally expand as much as the bolted wall portions, resulting in that the inner periphery of the center housing always keep its circularity when the inner temperature rises due to an unavoidable compression of air.
