Abstract

PURPOSE:To make it possible to produce a back pressure to secure a working oil pressure even if a relief valve is in an open condition by selecting a shorter stroke length of a poppet of the relief valve arranged at a control valve for controlling the pressure oil in a power line. CONSTITUTION:An overload relief valve 40 is installed in a hole 150 defined in a main body 32 of a steering control valve and consists of a valve portion 152 and a seat portion 154. A valve body 156 is freely slidably fitted in the hole 150 and its tip portion is formed into a cylindrical portion 158 within which is formed a hole 166. At the base end portion of the valve body 156 is screw-attached a holding member 168 to which is fixed a rod member 172. A poppet 176 is forced by a spring force of a coil spring 170 in the direction of the arrow C so that a tapered surface 174 is pressed against one end of the hole 166. The stroke of the poppet 176 is chosen sufficiently small within the range for the cylindrical body to be capable of slide movement.
