Title
(EN) COMPRESSOR AND OXYGEN CONCENTRATOR USING THE SAME
(FR) COMPRESSEUR ET CONCENTRATEUR D'OXYGÈNE L'UTILISANT
(JA) コンプレッサ及びこれを用いた酸素濃縮装置
Abstract
(EN)
A compressor which is drastically reduced in size, weight, noise, and vibration at the same time, and an oxygen concentrator using the compressor. A compressor is provided with a set of a first piston, a first eccentric cam, and a first cylinder chamber, a set of a second piston, a second eccentric cam, and a second cylinder chamber, a set of a third piston, a third eccentric cam, and a third cylinder chamber, and a set of a fourth piston, a fourth eccentric cam, and a fourth cylinder chamber.  A first center axis common to the first piston and the second piston and a second center axis common to the third piston and the fourth piston are arranged perpendicular to each other.
(FR)
L'invention porte sur un compresseur qui est réduit de façon drastique en termes de dimension, poids, bruit et vibration, en même temps, et sur un concentrateur d'oxygène l'utilisant. Un compresseur comporte un ensemble d'un premier piston, d'une première came excentrée et d'une première chambre de cylindre, un ensemble d'un deuxième piston, d'une deuxième came excentrée et d'une deuxième chambre de cylindre, un ensemble d'un troisième piston, d'une troisième came excentrée et d'une troisième chambre de cylindre, et un ensemble d'un quatrième piston, d'une quatrième came excentrée et d'une quatrième chambre de cylindre. Un premier axe central commun au premier piston et au deuxième piston et un second axe central commun au troisième piston et au quatrième piston sont disposés perpendiculairement l'un à l'autre.
(JA)
 大幅な小型軽量化と低騒音化と低振動化を同時に達成できるコンプレッサ及びこれを用いた酸素濃縮装置を実現することを目的とする。1組の第1のピストンと第1の偏心カムと第1のシリンダ室と、1組の第2のピストンと第2の偏心カムと第2のシリンダ室と、1組の第3のピストンと第3の偏心カムと第3のシリンダ室と、1組の第4のピストンと第4の偏心カムと第4のシリンダ室とを備え、前記第1のピストンと第2のピストンに共通する第1の中心軸と、前記第3のピストンと第4ピストンに共通する第2の中心軸とが互いに直交するように配置されている。
