Structure and inner electrical connection

The oil pressure control valve is connected via a 2-pin plug connection.

The oil pressure control valve is closed when de-energized. This means the oil circuit is automatically in the fallback level in the event of failure of the oil pressure control valve and the pressure limiting valve ensures an oil pressure of approx. 5.5 bar. During characteristic map operation, the oil pressure lies between 1.5 and 4.5 bar.
