From there the oil is conveyed to the pressure side of the gear wheel pump, where the oil is pressurized.
- Page 25 5.8.6 LE-S System Note! The *LE-S pump has an integrated check-valve function at the solenoid valve, allowing the oil pressure to expand backwards during standstill. The desired function of avoiding the formation of drops on the nozzle can only be achieved by using both the LE-S pump and the LE valve built into the FPHB- LE preheater.
