Title
(EN) LINEAR COMPRESSOR
(FR) COMPRESSEUR LINÉAIRE
(KO) 리니어 압축기
Abstract
(EN) A linear compressor according to an embodiment of the present invention is characterized by comprising: a cylinder having a refrigerant compression space formed therein; a piston which is inserted into the cylinder and expands or compresses the compression space while reciprocating in the axial direction of the cylinder, the piston having a plurality of suction holes formed in a front surface thereof; a suction valve which is coupled to the front surface of the piston and selectively opens and closes the plurality of suction holes; a guide which passes through the center of the suction valve and is inserted into the piston; and a fastening member which has a body portion that is inserted into the guide and a head portion that is hooked to a front end of the guide, wherein the guide protrudes from the front surface of the piston, and when the piston reciprocates linearly, the suction valve, due to inertia, moves along the guide in the opposite direction relative to the moving direction of the piston.
(FR) Compresseur linéaire selon un mode de réalisation de la présente invention caractérisé en ce qu'il comprend : un cylindre ayant un espace de compression de fluide frigorigène formé à l'intérieur de celui-ci ; un piston qui est introduit dans le cylindre et dilate ou comprime l'espace de compression tout en étant animé d'un mouvement de va-et-vient dans la direction axiale du cylindre, le piston comportant une pluralité de trous d'aspiration formés dans une surface avant de celui-ci ; une soupape d'aspiration qui est accouplée à la surface avant du piston et ouvre et ferme de manière sélective la pluralité de trous d'aspiration ; un guide qui passe à travers le centre de la soupape d'aspiration et qui est introduit dans le piston ; et un élément de fixation qui comporte une partie corps qui est introduite dans le guide et une partie tête qui est accrochée à une extrémité avant du guide, le guide faisant saillie à partir de la surface avant du piston, et lorsque le piston effectue un mouvement de va-et-vient linéaire, la soupape d'aspiration, en raison de l'inertie, se déplace le long du guide dans la direction opposée par rapport à la direction de déplacement du piston.
(KO) 본 발명의 실시예에 따른 리니어 압축기는, 내부에 냉매 압축 공간을 형성하는 실린더; 상기 실린더의 내부에 삽입되고, 상기 실린더의 축방향으로 왕복 운동하면서 상기 압축 공간을 팽창 또는 압축시키며, 전면에 다수의 흡입공이 형성되는 피스톤; 상기 피스톤의 전면에 결합되어, 상기 다수의 흡입공을 선택적으로 개폐하는 흡입 밸브; 상기 흡입 밸브의 중심을 관통하여 상기 피스톤에 삽입되는 가이드; 및 몸통부는 상기 가이드의 내부에 삽입되고, 머리부는 상기 가이드의 전단부에 걸리는 체결 부재를 포함하고, 상기 가이드는 상기 피스톤의 전면으로부터 돌출되고, 상기 흡입 밸브는, 상기 피스톤이 직선 왕복운동 할 때, 관성에 의하여 상기 가이드를 따라 상기 피스톤의 이동 방향에 반대되는 방향으로 상대 이동하는 것을 특징으로 한다.
