Abstract

The invention discloses a unilateral spring linear compressor. The unilateral spring linear compressor comprises a linear motor, a piston, a cylinder, a resonant spring unit, an air sucking and exhausting unit and an oil pump, wherein the linear motor is composed of a linear motor stator and a linear motor rotor; the linear motor rotor does linear reciprocating motion; one end of the piston is connected with the linear motor rotor an does linear reciprocating motion in the cylinder to compress a working medium; a compression cavity is formed between the cylinder and the piston; the air sucking and exhausting unit is located at the end part of the cylinder which is opposite to the head part of the piston; and one end of the resonant spring unit is connected to the linear motor rotor while the other end thereof is connected with a compressor body to store / release energy when the piston does the reciprocating motion. As the resonant spring unit of the linear compressor is arranged at one side of the linear motor rotor, and the compressed gas is utilized as a gas spring to reduce the usage of resonant springs, the unilateral spring linear compressor, disclosed by the invention, has the advantages of reducing the usage of the springs and the quantity of moving parts of the compressor, reducing motion inertia of the compressor and realizing the purpose of lightening the linear compressor.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a single-side spring linear compressor. Background technique [0002] A compressor is a mechanical device that receives energy from an energy output machine (such as a motor) to compress gas to increase gas pressure or deliver gas. Generally, compressors can be classified into reciprocating compressors, rotary compressors, and scroll compressors. The working principle of the reciprocating compressor is that the working medium is sucked into the compression space between the piston and the cylinder, and the piston makes a linear reciprocating motion in the cylinder to compress the gaseous working medium. After compression, the working medium rises in pressure and is discharged from the compression space. [0003] The traditional reciprocating compressor is driven by a rotary motor, which requires mechanical components such as a crankshaft to convert the rotary motion of the d...
