<p>PROBLEM TO BE SOLVED: To provide a fluid controller capable of compensating a leak stream generated in a steering actuator efficiently. SOLUTION: This fluid controller 27 is used in a device 45 provided with an inlet 47 and an outlet 49 and a leak stream passage therebetween and operated by a fluid pressure. The fluid controller 27 is provided with a main stream passage and a bleed passage provided with a variable bleed orifice AB. The variable bleed orifice AB brings a flow region to zero substantially when a valve is at a neutral position N and a usual operation position R and starts to open when the valve 61 approaches the maximum displacement position R-M.</p> |
