Abstract

본 발명은 피스톤 간극유지장치에 관한 것으로 특히 리니어(Linear) 콤퓨레셔의 구동방식에서 영구자석을 이용하여 피스톤과 실린더와의 간극을 유지시킬 수 있도록 하는 것으로서, 실린더내의 피스톤이 자력에 의하여 중심을 유지하도록 실린더의 주연에 영구자석을 구비한 것이다.The present invention relates to a piston clearance maintaining device, and in particular, to maintain a clearance between a piston and a cylinder by using a permanent magnet in the driving method of a linear compressor. Permanent magnets are provided at the periphery of the cylinder to hold.
