<P>PROBLEM TO BE SOLVED: To provide an oxygen concentrator in which low vibration, low noise and a simple structure can be achieved, and power consumption can be reduced by using a rotary cylinder device of which the compressor has a combination of a rotary motion with a reciprocating linear motion. <P>SOLUTION: A compressor 105 includes a rotary cylinder device 300 which forms a compressed-air-generating part 105a and a negative-pressure-air-generating part 105b alternately, by reciprocating motion of linear-motion pistons 301 and 302 within the cylinder 321 which are linked to a core-deviated cylindrical body 303 revolving around a crank axis 308 which is deviated from the axial core of a driving axis 331. <P>COPYRIGHT: (C)2011,JPO&INPIT |
