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.

Abstract: A hermetic compressor may include a plurality of springs provided between a compressor body and a shell to elastically support the compressor body and to space the compressor body apart from an inner surface of a shell. A plurality of spring caps fixed to the inner surface of the shell and the compressor body may support ends of each of the plurality of springs. Each of the plurality of springs may be inclined with respect to an axial direction. Transverse stiffness of the support springs may be increased to thereby reduce vibration noise of the compressor body and prevent the compressor body from being in contact with the shell.

Abstract: Provided is a linear compressor. The linear compressor includes a shell, a compressor body disposed in the shell, and a first support device coupled to a front portion of the compressor body in an axial direction to support the compressor body. The first support device may be disposed between an inner circumferential surface of the shell and the compressor body to support the compressor body in a radial direction.
