- Transmission 722.9
- Regelmagnetventil Kupplungssteuerung K1

Component Identification:

Location
The clutch control solenoid valve K1 is mounted on the fully integrated transmission control controller unit.

Task
The clutch control solenoid valve K1 is actuated by the fully integrated transmission control control unit and influences the position of the regulating valve K1. The pressure in the multidisk clutch K1 depends on the position of the regulating valve and therefore on the geometry of the regulating valve K1. The clutch control solenoid valve K1 has a rising characteristic.

This means that the oil pressure applied in the K1 regulating valve increases as the actuation current increases. In limp-home mode of the fully integrated transmission control (VGS) all the control solenoid valves are de-energized. The clutch control solenoid valve K1 thus supplies no pressure.

Body
In the clutch control solenoid valve K1, a proportional solenoid converts the electrical signals from the fully integrated transmission control control unit. The float needle can also be moved into intermediate positions as a result.

Function
The clutch control solenoid valve K1 assigns a proportional pressure to the current which is controlled by the fully integrated transmission control control unit.
