GF46.50-P-5140TX SPS (PML) Solenoid Valve, Component Description

GF46.50-P-5140TX SPS [PML] solenoid valve, component description

Component Identification:

Task
The SPS [PML] solenoid valve regulates the steering wheel torque in the speed range from v = 0 km/h up to v = 100 km/h.

Design
The SPS [PML] solenoid valve is a current-regulated proportional valve.

Component Identification:

Function
The electronics for the actuation of the SPS [PML] solenoid valve is integrated in the ESP control unit (N47-5). The SPS [PML] solenoid valve is actuated pulsed. As the vehicle speed increases the current flow decreases and the SPS [PML] solenoid valve opens the control valve as per a characteristic defined in the ESP control unit.

This regulates the oil flow and thus the torque to be applied to the steering wheel. The control valve is closed if the SPS [PML] solenoid valve is actuated with the maximum current (v = 0 km/h) No oil flows and the minimum steering wheel torque is set (situation for parking).
