Abstract

Disclosed herein is a linear compressor wherein a piston and a cylinder are arranged to extend vertically in a shell, and oil suction paths are formed in the cylinder for introducing oil stored in the shell into a space between the cylinder and the piston without requiring oil pumping parts, whereby a simplified oil supply structure can be accomplished via a reduced number of parts, and therefore, manufacturing costs and assembling time can be reduced.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a linear compressor, and more particularly, to a linear compressor in which a piston and a cylinder are arranged to extend vertically and oil suction paths are perforated through a wall of the cylinder to supply oil into the cylinder, whereby the oil supply structure of the compressor is simplified, and thus, manufacturing costs and assembling time of the compressor can be reduced.

[0003] 2. Description of the Related Art

[0004] Generally, a linear compressor is an apparatus configured in such a fashion that a piston reciprocally moves in a cylinder upon receiving a linear drive force of a linear motor to perform suction, compression, and discharge operations of fluid, such as gaseous refrigerant, (hereinafter, referred to as “fluid”).

[0005] FIG. 1 is a sectional view illustrating a conventional linear compressor.

[0006] As shown in FIG. 1, the conventional linear compressor comprise...
