Abstract: A reciprocating compressor is provided that may include a shell including a vibration absorbing member formed to be wound around an outer circumferential surface or an inner circumferential surface or stacked thereon, so that compressor vibration may be attenuated by frictional contact between the shell and the vibration absorbing member or between layers of the vibration absorbing member. Also a noise insulating layer may be formed between the shell and the vibration absorbing member or between the layers of the vibration absorbing member, so that a magnitude of noise may be reduced as vibration noise passes through the noise insulating layer, whereby vibration noise of the compressor, such as noise of a high frequency band, may be further attenuated by fine vibration.

Abstract: A reciprocating compressor is provided for which natural frequencies of a front side support spring and a rear side support spring are formed to be different such that a natural frequency of one support spring is lower than an operating frequency and a natural frequency of the other support spring is higher than the operating frequency, whereby both support springs may resonate in mutually opposite directions to form an antiphase, and thus, compressor vibrations may be effectively reduced without reducing a stiffness of both support springs.

Abstract: A refrigerator and a noise-reducing device mounted thereto are disclosed. The disclosed noise-reducing device, which comprises a hollow resonance chamber and a tubular acoustic filter inserted into the resonance chamber, is mounted at the side surface of a machine compartment, whereby not only heat due to the operation of a compressor is charged out of the machine compartment, but also noise transmitted from the compressor to the outside of the machine compartment is reduced through diffraction and resonance effects.
