Abstract
Disclosed herein is a linear compressor, which is designed in such a fashion that oil is suctioned into a space between a cylinder and a piston by a low pressure produced between the cylinder and the piston when the piston moves backward, and then is discharged to the outside by a high pressure produced between the cylinder and the piston when the piston moves forward, resulting in a simplified oil pumping structure and low cost.
