Hydrostatic Steering with Power-Beyond Capability 740435

Integration of the power steering function into varied control hydraulic systems of mobile equipment requires an adaptive steering valve. The new Ross 5-line Hydraguide meets the criteria and introduces unique flexibility to steering circuit design.
This paper highlights a positive displacement-type hydrostatic steering unit with an integral priority steering feature and an additional fifth port connection for a secondary hydraulic function. This concept of power-beyond capability in hydrostatic steering is discussed and its versatility demonstrated. It is shown that the power-beyond Ross Hydraguide provides simplified hydraulic circuitry and increased power utilization at moderate cost for off-highway machinery.
