Abstract: front page image
(EN)To provide a reciprocating compressor which may be improved in its efficiency and life, and can be small-sized and reduced in its noise and vibration. The reciprocating compressor (1) comprises a motor having a motor shaft (2s), four cylinders (4) disposed along the direction orthogonal to the axial direction of the motor shaft (2s), and four pistons (5) in that piston head parts (5h), each of which is so fitted into each of the four cylinders (4) as to be capable of reciprocating, and rod parts (5R) rotatably fitted into an eccentric shaft (17) secured to the motor shaft (2s) are formed integrally with each other.
(FR)L'invention concerne un compresseur à piston dont la durée de vie, la taille, le bruit et les vibrations peuvent être améliorés. Le compresseur à piston (1) comporte un moteur et un arbre de moteur (2s) ; quatre cylindres (4) disposés le long de la direction orthogonale à la direction axiale de l'arbre de moteur (2s) ; et quatre pistons (5) situés dans la partie de tête de piston (5h), chaque piston étant situé dans l'un des quatre cylindres (4) de façon à avoir un mouvement de va-et-vient ; des parties de tige (5R) ajustées rotativement sur un arbre excentrique (17) assujetti à l'arbre moteur (2s) sont formées d'un seul tenant les unes aux autres.
(JA) 高効率化、長寿命化、小型軽量化、さらには低騒音・低振動を実現可能とする。  往復動圧縮機1は、モータ軸2sを有するモータと、モータ軸2sの軸方向に対して直交する方向に沿うように配置される4つのシリンダ4と、4つのシリンダ4のそれぞれに往復動可能に嵌合されたピストンヘッド部5hと、モータ軸2sに固定された偏心軸17に回転可能に嵌合されたロッド部5Rとがそれぞれ一体になっている4つのピストン5とを有している。
