Manual Extract: Steering System

The pilot operating method is adopted in the steering system. A small amount of pilot oil supplied from the Orbitrol® controls the steering valve to realize steering operations.

When the steering wheel is turned, oil at a flow rate proportional to the turning speed is sent from the Orbitrol®
and supplied to the oil pack of the steering valve.

At this time, the pilot pressure is generated. The pilot pressure strokes the spool of the steering valve, and
supplies hydraulic oil at large flow rate proportional to the flow rate of the supplied pilot oil to the cylinder line.

The excessive pilot oil flows through the steering valve to the other side of the pilot port.
Shortly before the full turn, the stop valve activates, the pilot circuit is closed.
While the steering wheel is not turned, almost all
amount of hydraulic oil from the steering pump is sent to the loading line by the action of the flow control spool.

The pilot oil pressure from the steering pump is limited by the reducing valve, then supplied to the Orbitrol®.
Oil returns from the steering cylinders flows through the steering valve and oil cooler or cooler bypass valve.

Finally it returns to the tank through the return filter.

When the oil is very cold it will pass very slowly through the orifice. As a result it will take longer than normal for the spool to shift to neutral or holding position. Always warm up the oil before beginning normal operation.
