In the vacuum systems (Fig. 13) the return line should terminate
within the oil tank at the same level as the suction line.
In this case a non-return valve is not required.
Should however the return line arrive over the fuel level, a
non-return valve is required.
This solution however is less safe than previous one, due to the
possibility of leakage of the valve.
H-H1 = Difference of level
= Max. lenght of the suction line
L
I.D. = Interminal diameter of the oil pipes
