<p>A linear compressor including a well-closed container filled with oil at its bottom; a compressive unit having a frame of a hollow inside the well-closed container to which a cylinder inserted, a piston inserted into the hollow of the cylinder, for linearly moving upward and downward by driving of a motor installed at the cylinder, and a discharge cover for covering one end of the cylinder; and an oil supply unit mounted at the lower side of the compressive unit, for pumping oil, wherein the oil supplied from the 01oil supply unit to the compressive unit exists within the compressor unit in either case that the compressor is operated or stopped. Accordingly, even when the compressor is stopped, the oil remains in the compressive unit, so that when the compressor is re-started, the friction portion between the cylinder and the piston is lubricated, preventing abrasion of the friction portion. Thus, a reliability of the compressor is highly improved.</p> |
