GF27.19-P-5170AHI Working pressure control solenoid valve, component description
- TRANSMISSION 722.930

Component Identification:

Location
The working pressure control solenoid valve (VGS) is positioned on the electric controller unit (VGS).

Task
The working pressure control solenoid valve (VGS) is actuated by the fully integrated transmission control unit and influences the position of the working pressure regulating valve. The working pressure depends on the regulating valve position and thus on the geometry of the working pressure regulating valve. The working pressure control solenoid valve (VGS) has a lowering characteristic.

This means that the oil pressure applied in the working pressure regulating valve reduces as the actuating current increases. In limp-home mode of the fully integrated transmission control all the control solenoid valves are de-energized. The working pressure control solenoid valve (VGS) thus supplies maximum pressure.

Function
In the working pressure control solenoid valve (VGS) a proportional solenoid converts the electrical signals from the fully integrated transmission control unit (VGS). The float needle can also be moved into intermediate positions as a result.

The working pressure control solenoid valve (VGS) assigns a proportional pressure to the current which is controlled by the fully integrated transmission control (VGS) control unit.
