    • A product pump (154) for pumping separated product gas from an oxygen concentrator (100) which produces oxygen-rich product gas by utilizing a vacuum swing adsorption (VSA) process. The oxygen concentrator (100) comprises a cartridge (206) containing an adsorbent material (282) for separating the product gas from ambient air, a vacuum pump (144) which provides a vacuum source, a valve (140) for selectively connecting the vacuum pump (144) to the cartridge (206) and product pump (154), and a reservoir (158). The product pump (154) comprises a pumping chamber (265) having a product gas inlet (261) and a product gas outlet (263), a piston (262) movable in the chamber (265), a vacuum inlet (172) in the chamber (265) on an opposite side of the piston (262) from the product gas inlet (261) and outlet (263) for providing a vacuum to cause the piston (262) to draw product gas through the product gas inlet (261) into the chamber (265), and a spring (264) for providing a spring force to force the product gas out the product gas outlet (263).
    • 一种用于从氧浓缩器(100)泵送分离的产物气体的产品泵(154),其通过利用真空摆动吸附(VSA)方法产生富氧产物气体。 氧浓缩器(100)包括容纳用于将产品气体与环境空气分离的吸附材料(282)的盒(206),提供真空源的真空泵(144),用于选择性连接真空的阀(140) 泵(144)到料筒(206)和产品泵(154)以及储存器(158)。 产品泵(154)包括具有产品气体入口(261)和产品气体出口(263)的泵送室(265),可在室(265)中移动的活塞(262),真空入口 在活塞(262)的与产品气体入口(261)和出口(263)相反的一侧的腔室(265),用于提供真空以使活塞(262)将产物气体通过产物气体入口(261) )和用于提供弹簧力以将产品气体压出产品气体出口(263)的弹簧(264)。
