Abstract
A linear compressor includes a spring axially elastically supporting a driving assembly. The spring includes a spring body axially extending, a front spring link forming an end of the spring body by extending from a side of the spring body, and a rear spring link forming the other end of the spring body by extending from the other side of the spring body. Any one of the front spring link and the rear spring link is fixed to the driving assembly and the other one is fixed to a supporting assembly.
Claims20
A linear compressor comprising:
- a driving assembly configured to reciprocate in an axial direction;
- a spring that supports the driving assembly in the axial direction;
- and
- a bracket coupled to the spring and the driving assembly,
- wherein the spring comprises a plurality of spring strands, each of the plurality of spring strands comprising:
- a spring body that spirally extends about a spring central axis extending in the axial direction,
- an inside end portion that extends from a first side of the spring body and that is coupled to the bracket, and
- an outside end portion that extends from a second side of the spring body.
