Although Pr8 is considered to have the highest contribution to the top event according to failure probability, Pr3, check valve fails, and Pr5, operator error when under pressure are both considered the most sensitive to the FWI and therefore removing these errors in operation will improve the ...
hydraulic fluid flow to and from the actuator. For instance, the valve can control flow from the pump to the actuator and flow from the actuator to a tank or reservoir. The valve is controlled to vary the resistance to flow so as to control the speed and direction of motion of the ...

control line52for supplying current to the valve54. For example, the hydraulic inputs of the two actuators36shown inFIG. 2504848and associated hydraulic interconnections are shown. The controller44generates output control signals to the hydraulic control valve(s)4838,40,4248open and close in ...
The operation of the swash control valve 222 is to communicate pressurized fluid from a conduit 225 on the “high pressure” side of the system to the servo actuators 221 using conduits 219 as appropriate to achieve the desired angle and displacement of swash-plate 216, all of which is ...
Hydraulic fluid flow is regulated by an electrohydraulic control valve responsive to control signals from a main controller, wherein the control signals and corresponding control valve operation may be independent of engine speed and load. In addition, the hydraulic fluid is supplied to the hydraulic...
