Re. Fuel pumps.

Thank-you "Swiss Swiss" and "Sven Sixtoo".

If I have got it right, the fuel pumps work continuously at maximum rate (when switched on) and the actual fuel flow to the engines is controlled by the control valve AND spill valves which get rid of any excess pressure.

Are the spill valves actuated, or merely like saftey valves, operated mechanically by excess pressure ?


Thanks
