Abstract: A flow control valve has a supply line connection, and at least one discharge line connection, and is characterized by at least one fine-control valve whose flow rate is continuously or semicontinuously variable and at least one two-position valve having a minimum flow rate in one stable position and a maximum flow rate in another stable position. The inlet of the or each tow-position valve and the or each fine-control valve is in fluid communication with the supply line connection, and the outlet of the or each two-position valve and the or each fine-control valve is in fluid communication with the or each discharge line connection. In accordance with a further elaboration, the flow control valve may comprise a series of two-position valves, with the maximum flow rate of the successive two-position valves in the series doubling in each case, and the minimum flow rate of each two-position valve being zero.

Abstract: 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
