Simply parameterisable hydraulic motor vehicle power steering has proportional valve between pump, servomotor working chambers with input connected to pump's pressure side, output to working chambers

摘要

The system has a hydraulic servomotor (1) with working volumes supplied with hydraulic fluid under pressure by a hydraulic pump via a rotary slide valve (5) and an electrically controllable proportional valve between the pump and working chambers whose input is connected to the pressure side of the pump and whose output is connected to the working chambers and to the power steering return .
