Linear compressor

Abstract

The present invention relates to a kind of linear compressor, and the linear compressor has oil groove in at least one of the cylinder and piston to hold micro particle so that no residue remained in the contact surface between the cylinder and the piston. The present invention can avoid the damage on the surface one the cylinder and the piston caused by micro particle and reduce the friction loss between the cylinder and the piston.

Description

technical field [0001] The present invention relates to a kind of compressor, particularly relate to a kind of oil groove that is formed on at least one of the piston and the cylinder to silt up the tiny particles between the above-mentioned cylinder and the piston, so effectively prevent the cylinder and the piston from being damaged by the tiny particles. damage, thereby improving the wear resistance of the linear compressor (linear compressor). Background technique [0002] A general linear compressor (Linear compressor) is a machine that directly uses the driving force of a linear motor to make the piston in the cylinder reciprocate in a straight line, suck in oil, compress it, and then spit it out. [0003] figure 1 is the internal structure diagram of a general linear compressor, figure 2 It is a brief cut-away diagram of a general linear compressor piston and cylinder. [0004] Such as figure 1 with figure 2 As shown, a general linear compressor is provided wit...

Problems solved by technology

[0016] However, a general linear compressor has a piston and a cylinder because the relative movement thereof will cause wear between the above-mentioned cylinder 42 and the piston 30, because the wear of the above-mentioned piston 30 and the cylinder 42 generates fine particles or from the piston 30 and the cylinder 42. When fine particles flow in between the piston 30 and the cylinder 42 from the outside, the fine particles accumulated between the piston 30 and the cylinder will wear the contact surface between the piston 30 and the cylinder 42 and cause oil leakage. Friction occurs on the contact surface of the cylinder 42, reducing the durability of the above-mentioned piston 30 and cylinder 42, thereby reducing the efficiency of the linear compressor, etc.

[0017] This shows that above-mentioned existing compressor obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved
