A continuous fuel injection system for an internal combustion engine including a fuel metering valve 7 operating at a controlled pressure difference between chambers 13,14, the pressure difference being automatically adjusted by a regulating valve 17 including a diaphragm 18 separating two chambers 19,20. Chamber 20 is connected to relief 60 via a movable valve element 35 and the second chamber 19 is connected to the pressure upstream of the metering valve. The pressure difference is determined by a spring system acting on the diaphragm 18 including a stronger spring 33 which acts directly on the diaphragm and a weaker spring 34 which acts as a contact spring holding the valve body 35 lightly in contact with the diaphragm. |
