    摘要: A variable assist power steering system employing a fluid distributor circuit of the open center type is disclosed. The fluid distributor circuit includes two parallel fluid flow paths connected to both chambers of a power cylinder respectively to produce a pressure differential between the both cylinder chambers in response to steering torque. For modulating the valve characteristics, two additional variable flow restrictors are arranged in series with two main variable flow restrictors and two bypass paths are arranged to bypass the main variable flow restrictors, respectively. The bypass paths are provided with variable flow orifice valves, respectively, which valves are controlled in response to a turning direction of a steering wheel and also to some external signal, such as vehicle speed.

    摘要: In a hydraulic shovel operability range display device, a calculation unit is configured to set a boundary between an operability range and an underbody area along a vertical direction in a global coordinate system when a vehicle body is horizontally oriented. When the vehicle body is tilted forward, the calculation unit is configured to set the boundary so as to be maintained along the vertical direction in the global coordinate system. When the vehicle body is tilted backwards, the calculation unit is configured to correct the boundary between the operability range and the underbody area so that an angle formed by the boundary and the ground surface on which the vehicle body is positioned is at least 90°.
