Abstract
PURPOSE:To lessen the dead band of a steering wheel while improving the responsive property by operating a flow pressure controlling valve to amplify pilot flow. CONSTITUTION:Flow pressure controlling valves 7a, 7b at the meter-out side are constructed to be poppet valve type two-way valves which have springs 8, 8' for urging the valves in the closing direction, closing pilot ports 10, 10' acting in the closing direction and connected through variable throttle valves 9, 9' to the upstream side circuit, the up-stream side opening pilot ports 11, 11' acting in the opening direction and connected to the up-stream side circuit and the downstream side opening pilot ports 12, 12' acting in the opening direction and connected to the down-stream side circuit. On the other hand, flow pressure controlling valves 6a, 6b at the meter-out side are constructed to be poppet valve type two-way valves similarly to said valves 7a, 7b, A pilot pipe line 23 introduced from a pilot port LS of a metering pump 14 is connected to a pilot port 21a of a pressure controlling valve 21.
