Abstract
PURPOSE:To enable usage of a small capacity steering valve by constituting a hydraulic steering circuit for caterpillar vehicle with a steering valve for feeding pressure oil to one of right or left steering cylinder and a pilot valve for controlling pressure oil supply to the other steering cylinder. CONSTITUTION:Delivery oil pressure from hydraulic pumps 1, 2 driven through engines is fed through a demand valve 3 and a steering valve 4 respective head sections 5a of a pair of steering cylinders 5, 5, where a portion thereof is branched in the downstream of the demand valve 3 and fed through a working machine operational valve 6 to a working machine cylinder 7 and a pilot valve 21. The pilot valve 21 is fed with pressure at the head 5a side of the steering cylinder 5 through pilot circuits 22, 23 and pressure at the bottom 5b side through pilot circuits 24, 25. The pilot valve 21 is switched by the pressure oil fed to one steering cylinder 5 so as to control pressure oil supply to the other steering cylinder 5.
