<P>PROBLEM TO BE SOLVED: To provide a hydraulic controller necessitating no processing of the components of a valve device so as to apply a braking force to a trochoid rotor by a hydraulic force applied in a brake pressure chamber to suppress a handle slip phenomenon and not to apply any braking force on the trochoid rotor when a normal steering operation is carried out. <P>SOLUTION: A fluid distribution path 126 is formed between a brake pressure chamber 101 and a relief valve 11 and communicated with a relief flow path 116 formed in a relief valve 11 to release the pressure of the brake pressure chamber 101 to a tank via the relief path 116 when the relief valve 11 is not operated. When the relief valve 11 is operated, the flow distribution path 126 is discommunicated from the relief flow path 116, and communicated with a pressure flow path 114 formed in the relief valve 11 to feed a hydraulic force for operating the relief valve 11 from the pressure path 114 through the fluid distribution path 126 to the brake pressure chamber 101. <P>COPYRIGHT: (C)2013,JPO&INPIT |
