What is the name of the solenoid valve used by BMW to adjust the valve oil pressure?

VANOS solenoid valve servo motor controls eccentric shaft. (The eccentric shaft is connected with the valve to adjust the valve)

When equipped with electronic valve control system, detect the position of eccentric shaft. The eccentric shaft adjusts the camshaft so that the best intake valve lift can be achieved in each working state (the intake valve lift can be adjusted steplessly). The eccentric shaft is adjusted by an electronic valve-controlled servo motor.
