Linear compressor

Abstract

Disclosed herein is a linear compressor. In the present invention, a spring sheet is equipped in an exhale cover to prevent an edge and an outer circumference of an exhale spring from touching with the exhale cover. A surface of the spring sheet is treated with a metal of the high hardness, thereby protecting against its abrasion and transformation, caused by a repetitive load from the exhale spring. Furthermore, the durability is improved by enduring the excessive or local load from the exhale spring.

Description

technical field [0001] The present invention relates to a linear compressor, more particularly, capable of preventing wear and deformation of a discharge spring and a discharge cover caused by a load of the discharge spring. Background technique [0002] In general, a linear compressor is a machine that sucks, compresses, and discharges fluid by linearly reciprocating a piston in a cylinder by a linear driving force of a linear motor. [0003] figure 1 shows a linear compressor according to the prior art; figure 2 The structure of the discharge part of the linear compressor according to the prior art is shown. [0004] In a hermetic casing 2 of a conventional linear compressor, a cylinder block 4 provided with a cylinder 3 and a back cover 6 provided with an inlet 5 are installed. The cylinder block 4 and the rear cover 6 are supported in the sealed casing 2 by the main shock absorber 7 and the auxiliary shock absorber 8 to absorb shocks (see figure 1 ). [0005] A lin...
