Hydraulic vehicle-steering circuit

摘要

Hydraulic vehicle-steering circuit having wheel-adjusting cylinders (13, 14) and having a pressure-medium pump (2), the volumetric flow of which can be changed and is set to a low value when the steering wheels are straight or are deflected to a small extent and is set to a higher value when the steering wheels are deflected to a greater extent. The low value is defined by a metering orifice (26) at which a defined pressure drop is observed at all times. When the steering wheels are deflected to a greater extent, a servo control valve (12) responds, via which the additional (greater) volumetric flow is channelled to the wheel-adjusting cylinders (13, 14). <IMAGE>
