特徴とする油圧回路。 In a hydraulic circuit configured such that a hydraulic pilot valve and a hydraulic pilot switching valve are connected by a pilot pipe, and the hydraulic pilot switching valve is switched by controlling working fluid by the hydraulic pilot valve, at least a portion of the pilot switching valve is connected to the hydraulic pilot switching valve. A hydraulic circuit characterized in that a fluid having a lower viscosity than the working fluid controlled by the hydraulic pilot valve is filled inside a conduit, and the low viscosity fluid is separated by the working fluid separating means.
