Control circuit for hydraulic steering for vehicle

摘要

The hydraulic system for the vehicle has a single hydraulic pump to supply several hydraulic circuits including the hydraulic steering. The steering has priority and is fitted with a non-return valve (12) to isolate the steering circuit from the remainder of the hydraulics as well as a pressure reservoir (13) to cover pressure fluctuations.The pressure reservoir is positioned downstream of the non return valve and is filled from the supply. If the steering is returned to neutral and is immediately reset then the temporary drop in system pressure is compensated by the pressure reservoir.
