Title: A Linear Compressor
Inventor: OM JAE PUNG
IPC: F04B39/12
Filed: 2017-12-04
Abstract: The present invention relates to a linear compressor and, more specifically, to a linear compressor capable of providing a dual function including guiding and center-maintaining to provide a guide function while maintaining the center by coming into contact with the internal surface of a cylinder in the middle part of a piston. Since most linear compressors have a structure including a piston operation part and a gas compression part which are separated to be operated, the structure has to be complex, noise is generated, and the volume can be high. Accordingly, a linear compressor cannot be large and has to be limited to small domestic appliances, and only a one-way compressor performing absorption and discharge through only one side of a cylinder can be manufactured, which is a structural weakness. Therefore, since the linear compressor performs both guiding and center-maintaining through the repulsion and gravitation of a magnet and performs absorption and discharge through both sides around a piston, the compressor does not make a pulsatory motion and functions as a cushion with compressed pressure, so the compressor is simplified, has a large capacity and generates less noise.
