  • Directional-control valve
    Patent number: 6916003
    Abstract: Disclosed is a directional control valve comprising a front-side connector and at least one radial connector, wherein the front faces of a valve body (valve shift or seat body) of the directional control valve are pressurized approximately equally, so that the actuating forces for shifting the valve body are minimal. In accordance with the invention, the pressure for pressurizing a rearward front face of the valve body is tapped at an axial distance to the valve body.
    Type: Grant

  • Control motor for a servo-valve
    Patent number: 5140203
    Abstract: A control motor for a servo-valve includes elements of a control motor including a yoke, permanent magnet, control coil and armature mounted to one another. An output member transmits the pivotal movements of the armature. A frequency dependent passive electric dampening means is formed as an annular disc, and located adjacent the control means to compensate for non-linearities in frequency response.
