Patent ID: 7722335

Claim:
A linear compressor comprising: a shell; a linear compression unit mounted in the shell to compress fluid using a linear driving force of a linear motor; a plurality of supporting springs provided between the shell and the linear compression unit to support the linear compression unit in a shock-absorbing manner; a plurality of spring seats configured to affix opposite ends of each supporting spring to the shell and the linear compression unit, respectively, the spring seats including a shell spring seat provided at the shell; the shell spring seat including: a shell coupling portion immovably coupled to the shell; a spring coupling portion formed around an outer circumference of the shell coupling portion and spaced apart from the shell coupling portion by a predetermined distance, the spring coupling portion being coupled to the supporting spring; and a buffer interposed between the shell coupling portion and the spring coupling portion of each shell spring seat adapted to absorb shock transmitted from the spring coupling portion to the shell coupling portion.
