    • An apparatus for compressing or pumping fluid includes a housing having an interior chamber. A rotating cam is rotatably mounted within an interior chamber and includes a reversible cam body configured to enable fluid to flow in a foreword direction and a reverse direction. The reversible cam body has a first sloped annular channel formed therein. The first end of the reversible cam body includes a ramp up portion, a ramp down portion, and inner and outer circumferential sidewalls that circumscribe the ramp to define the first sloped annular channel. The apparatus may include a circumferential cam gear located on the outer circumferential sidewall and a secondary drive shaft with a pinion gear to rotate the circumferential cam gear.
    • 用于压缩或泵送流体的装置包括具有内部室的壳体。 旋转凸轮可旋转地安装在内部腔室内,并且包括被配置为使得流体能够在前言方向和相反方向上流动的可逆凸轮体。 可逆凸轮体具有形成在其中的第一倾斜环形通道。 可逆凸轮体的第一端包括斜坡上升部分,斜坡下降部分以及围绕斜坡以限定第一倾斜环形通道的内圆周侧壁和外圆周侧壁。 该装置可以包括位于外周侧壁上的周向凸轮齿轮和具有小齿轮的副驱动轴,以使周向凸轮齿轮旋转。
