GF46.50-P-2500RT Speed-Sensitive Power Steering, Function With Vehicle Stationary

GF46.50-P-2500RT Speed-sensitive power steering, function with vehicle stationary
- up to model year 08

Component Identification:

Vehicle speed v = 0 km/h
The SPS solenoid valve is energized to the maximum possible extent and as a result closed against the force of the integral push spring. The pressure ratios in the reaction chambers are identical, since the pressure oil supply is stopped. No force acts on the reaction balls, no additional torque acts on the v-shaped surfaces of the rotary valve.

The steering is light, as the steering torque applied by the driver, consisting of overcoming the force of the torsion bar, is very low. Via the constant constriction orifice the oil flow is passed on to the power steering pump reservoir virtually depressurized.
