3.3.2 Oil supply
Oil pump
The pump draws the oil through the supply line and carries it under pressure to the
oil nozzle. The pressure regulating valve keeps the oil pressure constant.
A solenoid valve opens and closes the oil supply to the nozzle. The pressure regu-
lating valve and solenoid valve are integrated into the pump.
Nozzle head with nozzle shut off
The nozzle shut off is integrated in the nozzle head. It prevents oil leaks after shut-
down.
Heat exchanger
The heat exchanger in the nozzle assembly heats the oil. At an oil temperature of
approx. 45 °C the temperature switch releases the burner start.
