Abstract
A fuel flow control assembly comprises a metering piston which can slide within a casing and defines with that casing an upstream chamber at a pressures P.sub.1 and downstream pressure P.sub.2. Relative movement of the piston and the casing varies the effective opening of a metering orifice and providing that the pressure drop P.sub.1 -P.sub.2 is kept constant the orifice has linear characteristics. The assembly also includes a pressure drop monitor and a slide control valve which uses as its casing an internal bore of the flow control piston. With a view to rendering the assembly more compact the pressure drop monitor is also disposed within the bore of the flow control piston.
