    • A bellows pump which is provided with a case member that forms an axial space therein, closed-bottomed cylindrical bellows that are arranged in the space in an axially extendable/contractable manner and axially separate the space into a pump chamber and an operation chamber, suction valves that are provided on a suction side of the pump chamber and guide a fluid to be transferred to the pump chamber, and discharge valves that are provided on a discharge side of the pump chamber and discharge the fluid to be transferred from the pump chamber, and which extends/contracts the bellows by introducing a working fluid into the operation chamber to discharge the working fluid from the operation chamber, wherein each of the bellows is configured by alternately forming mountain portions and valley portions along the axial direction and having, on a predetermined position in the axial direction, annular ring portion integrally formed therewith.
    • 一种波纹管泵,其具有在其中形成轴向空间的壳体构件,封闭的圆柱形波纹管,其以可轴向延伸/收缩的方式布置在空间中并将空间轴向分离成泵室和操作室,抽吸 设置在泵室的吸入侧并引导要传递到泵室的流体的阀,以及设置在泵室的排出侧并排出要从泵室转移的流体的排出阀, 并且通过将工作流体引入到操作室中以使操作室排出工作流体来延伸/收缩波纹管,其中每个波纹管通过沿轴向交替地形成山部分和谷部而构成,并且在 在轴向上的预定位置,与其一体形成的环形环部分。
