Abstract: A linear compressor in which an inner core is integrally mounted with a magnet to linearly reciprocate simultaneously and is also mounted on a core frame that comes into close contact with an outer circumference of a cylinder. With this configuration, the core frame is able to stably support the weight of the inner core, resulting in improved rigidity and reliability of the compressor.

Abstract: Disclosed herein is a linear compressor. In the present invention, the configuration that a sealing protrusion is protruded in a sealing part of a cylinder toward an exhale cover leads line contact with the exhale cover and the sealing protrusion of the sealing part. Even though small power is applied to the exhale cover, the exhale cover and the sealing protrusion are closely adhered to each other, thus effectively sealing the exhale cover and the cylinder. Furthermore, as power transmitted from the exhale cover to the cylinder becomes reduced, a transformation of the cylinder can be prevented, and a performance and reliability of the linear compressor can be enhanced.
