    • A hydraulic flow valve apparatus has a valve body (10) providing a valve body cavity (20) with an eccentric sidewall (30). The sidewall terminates at a frontal surface (12) of the valve body (10) with a conical bottom surface (32) defining a flow aperture (40) at its apex. A sealing shaft (50) is fitted within the cavity (20) and is enabled for lateral movement due to the eccentric sidewall (30). The sealing shaft (50) provides at one end (52), a rubber seat (54) sealing the flow aperture (40), and at the other end (56), a planar surface (58) set at an off-normal angle. A fluid actuated vane (60) extends away from the frontal surface (12) of the valve body (10) and is pivotally engaged with the planar surface (58) of the sealing shaft (50) so as to move the sealing shaft laterally, so as to uncover the aperture (40) when the vane (60) is forced out of a selected preliminary alignment with the sealing shaft (50).
    • 液压流量阀装置具有阀体(10),该阀体提供具有偏心侧壁(30)的阀体腔(20)。 侧壁在阀体(10)的前表面(12)处终止于其顶点处限定流动孔(40)的锥形底表面(32)。 密封轴(50)装配在空腔(20)内并由于偏心侧壁(30)而能够横向移动。 密封轴(50)在一端(52),密封流动孔(40)的橡胶座(54)和在另一端(56)处提供设置在非法线角度的平坦表面(58) 。 流体驱动叶片(60)远离阀体(10)的前表面(12)延伸并且与密封轴(50)的平坦表面(58)枢轴接合,以使密封轴横向移动, 以便当所述叶片(60)被迫离开与所述密封轴(50)的选定的预定位置时露出所述孔(40)。
