Linear compressor

Abstract

The present invention relates to a linear compressor. In the linear compressor, a holder 31b is combined with a cylinder 22 in an interlocking fashion by forming a first threaded part 31c on an inner surface of the holder 31b, the outer side of which on an inner core 31a is mounted, and a second threaded part 22b on an outer surface of the cylinder 22 to correspond to the first threaded part 31c. That is, screws are not required when the cylinder 22 and the holder 31b are combined with each other, thus preventing the cylinder 22 from being deformed by a fastening torque of the screws.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of Korean Patent Application No. 2003-83189, filed Nov. 21, 2003 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates, in general, to a linear compressor and, more particularly, to a linear compressor having an inner core combined with an outside of a cylinder. [0004] 2. Description of the Related Art [0005] Generally, a linear compressor is used to compress a refrigerant of a refrigeration apparatus, such as a refrigerator and an air conditioner, and refers to a compressor adopting a linear motor, which reciprocates linearly, as a drive means to reciprocate a piston. [0006] A conventional linear compressor includes a compression unit to compress the refrigerant in a closed container, and a drive unit to provide power to the compression unit. [0007] The c...

AI Technical Summary

Benefits of technology

[0013] Accordingly, it is an aspect of the present invention to provide a linear compressor, which improves a combination structure of a holder, to which an inner core is fastened, with a cylinder block, thus preventing a cylinder from being deformed and reducing a number of manufacturing steps thereof.

Problems solved by technology

However, the conventional linear compressor requires additional parts, such as screws, to combine the holder with the cylinder block, so that problems arise in that manufacturing costs and a number of manufacturing steps increase, thus reducing manufacturing efficiency of the linear compressor.

Furthermore, a problem arises in that a deformation of the cylinder is incurred by a fastening torque of the screws, thus reducing reliability of the linear compressor.
