Abstract
A compressor includes: a case, a compression unit that is provided inside the case and that includes a cylinder and a piston configured to reciprocate inside the cylinder to compress refrigerant, a driving unit that includes a stator disposed inside the case and a plurality of permanent magnets configured to reciprocate with respect to the stator and that is configured to provide a driving force to the compression unit, and a resonator that is configured to reduce noises generated while the compression unit is operated, that is disposed between the compression unit and an inner surface of the case facing the compression unit in an axial direction, and that is spaced apart from the compression unit.
