Abstract
A low noise, hermetic motor-driven compressor suitable for used in a refrigerator or an air-conditioner is disclosed in which a closed container has a spherical wall portion on which a combined motor-and-compressor assembly is supported via a suspension mechanism, and the suspension mechanism includes two snubber stays having spherical portions complementary in contour to the shape of the spherical wall portion of the closed container and welded to the spherical wall portion. The spherical wall portion increases the stiffness of the closed container, which stiffness is enhanced by the spherical portions of the snubber stays. The thus reinformed closed container is unlikely to vibrate in resonance with the vibration of the combined motor-and-compressor assembly. Thus, the hermetic motor-driven compressor is able to operate silently.
