Abstract

The present invention provides a linear compressor having an elastic body capable of reducing vibration transferred to a shell due to a motion of a moving part. The linear compressor includes a shell defining a hermetic space, a stationary part installed in the shell and having a mass of Mb, a moving part reciprocating linearly inside the stationary part at a frequency of ω to compress a fluid, and having a mass of Ma, a first elastic body having both ends supported on the moving part and the shell respectively, and having an spring constant of ka, a second elastic body having both ends supported on the shell and the stationary part respectively, and having an spring constant of kb, and a third elastic body having both ends supported on the stationary part and the moving part respectively, and having an spring constant of k. The frequency ω satisfies ω2 > (ka /Ma ). In the above configuration, the spring constant kc of the third elastic body is always a positive number, so that the third elastic body can be implemented with a mechanical elastic body more easily designed and controlled than a gas elastic body.
