Linear compressor

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

technical field [0001] 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 a plurality of oil suction paths penetrate into the wall of the cylinder to supply oil into the cylinder, whereby the The oil supply structure of the compressor is simplified, thereby reducing the manufacturing cost and assembly time of the compressor. Background technique [0002] In general, a linear compressor is a device constructed in such a manner that a piston reciprocates in a cylinder while receiving a reciprocating driving force from a linear motor to perform a process such as a gaseous refrigerant (hereinafter referred to as "fluid"). Suction, compression and discharge operations of similar fluids. [0003] FIG. 1 is a sectional view showing a conventional linear compressor. [0004] As shown in FIG. 1 , a conventional linear compressor includes: a housing 2 in which oil ...

AI Technical Summary

Problems solved by technology

[0014] The problem with the conventional type linear compressor is that since it requires many oil suction parts, for example, an oil cylinder 44, an oil piston 45, a front oil spring 46 and a rear oil spring 47, its structure is complicated and assembly work is difficult, thereby increasing the manufacturing cost
