Abstract

PURPOSE:To reduce steering load by installing the first direction switching valve between an oil pressure source and a switching valve and also by installing the second direction switching valve between this valve and a power cylinder and by switching and operating them by a controller. CONSTITUTION:At the time of manual steering, a switching valve 3 is switched by the operation of a handle 1, pressure oil is supplied to a power cylinder 5 and steering rotation is executed. On the other hand, at the time of automatic steering, the direction switching valve 10 is switched by a controller 12, and pressure oil is set to the power cylinder 5 through a direction switching valve 11. And a signal is put into the controller 12 by the operation of an operation board 16, the direction switching valve 11 is switched and operated, and pressure oil is led to one of the oil chambers of the power cylinder 5 and the exhaust oil is returned to a tank 4B at the same time. By this, a steering can be rotated in the arbitrary direction, and steering load is drastically reduced.
