Continuous curvature noise suppressing compressor housing

摘要

A hermetic compressor housing formed from sheet metal as two housing halves which when joined form a generally ellipsoidal inner surface having a maximum radius of curvature of about one order of magnitude greater than the minimum radius of curvature and deviating from the generally ellipsoidal shape only where necessary for supporting a compressor-motor assembly therein and for joining the housing halves is disclosed and provides a housing of relatively uniform rigidity to reduce the level of sounds radiated thereby. In one specific embodiment all of the audible natural resonant frequencies of the housing are above 3500 Hz.
