Abstract

A hermetic compressor is provided. The hermetic compressor may include a compressor body spaced apart from an inner surface of a shell and including a motor unit and a compression unit; at least one support spring provided between the shell and the compressor body and that elastically supports the compressor body with respect to the shell; at least one stopper cap fixed to the inner surface of the shell or the compressor body facing the inner surface of the shell; and a stopper bar that extends from the compressor body or the inner surface of the shell and inserted into the at least one stopper cap with a predetermined distance therebetween. By mechanically restraining vibration of the compressor body and limiting amplitude of the compressor body, vibration noise of the compressor body may be reduced and the compressor body may be suppressed from being in contact with the shell to thereby prevent damage to the compressor body.
