Abstract

Disclosed herein are a linear compressor and a lubricating oil pump thereof. The lubricating oil pump comprises a lubricating oil cylinder integrally formed in a frame that supports a compression unit, a lubricating oil piston mounted to be reciprocated inside the lubricating oil cylinder to resonate with the compression unit, and a lubricating oil cylinder protector to prevent generation of friction between the lubricating oil cylinder and the lubricating oil piston. With this configuration, it is possible to improve the durability of the lubricating oil cylinder and to simplify or omit additional processing of the lubricating oil piston.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a linear compressor and a lubricating oil pump thereof, and, more particularly, to a linear compressor and a lubricating oil pump thereof, which comprises a lubricating oil cylinder protector to prevent generation of friction between a lubricating oil cylinder and a lubricating oil piston. [0003] 2. Description of the Related Art [0004] Generally, a linear compressor is an apparatus to compress operating fluid while linearly reciprocating a piston inside a cylinder using a linear driving force of a linear motor. [0005]FIG. 1 is a longitudinal sectional view of a linear compressor having a lubricating oil pump according to the prior art. The linear compressor shown in FIG. 1 includes a hermetic container 2, and a compression unit arranged in the hermetic container 2 to compress operating fluid. [0006] The compression unit includes a cylinder 10 to receive operating fluid from a fluid ...
