A fluid metering device, for instance for a fuel supply system of a combustion engine having combustion chambers, which fluid metering device comprises at least one supply line connection (1) and at least one discharge line connection (2), the fluid metering device being provided with two sets of outlet ports (3, 4) which put the or each discharge line connection (2) into fluid communication with a fluid chamber (5), which fluid chamber (5) is put into fluid communication, via at least one inlet port (6), with the at least one supply line connection (1), a first and a second regulating plunger (7 and 8 respectively) controlling the fluid flow rate through, respectively, the first and the second set of outlet ports (3 and 4 respectively) by covering at least partly the through-flow surface of, respectively, the first and the second set of outlet ports (3 and 4 respectively), each regulating plunger (7, 8) comprising energizing means (9 and 10 respectively) of its own for controlling the respective positions of the regulating plungers (7, 8).
A fluid metering device, for instance for a fuel supply system of a combustion engine having combustion chambers, said fluid metering device comprising at least one supply line connection, at least one discharge line connection, and two outlet ports which put the or each discharge line connection into fluid communication with a fluid chamber, said fluid chamber being put into fluid communication, via at least one inlet port, with the at least one supply line connection, a first and a second regulating valve controlling the fluid flow rate through the first and the second outlet port, wherein each regulating valve comprises energizing means of its own for controlling the respective positions of the regulating valves, characterized in that, the fluid metering device comprises two sets of outlet ports all of which create a combined flow volume which is simultaneously sent from the fluid chamber to the or each discharge line connection, wherein the first and second valve comprise a first and second plunger respectively controlling the fluid rate through, respectively the first and the second set of outlet ports by covering at least partly the through-flow surface of, respectively, the first and the second set of outlet ports by means of respectively the outer cylindrical surface of the first plunger and the outer cylindrical surface of the second plunger.
