ABSTRACT:
A hermetic electric compressor including sealed container and coil spring provided for elastically supporting electric compression element housed in sealed container. A consideration has been made to avoid the coincidence in the resonance frequency between coil spring mounted with electric compression element and mechanical vibration caused by electric compression element, or a cavity formed in space. By so doing, creation of a resonation with coil spring is suppressed, and noises and vibrations with the hermetic electric compressors are reduced.
