Abstract
The fuel distributing and metering assembly provides separate multiple metered fuel flows from a common fuel reservoir by including a rotary valve having multiple valve metering slots for generating separate multiple fuel flows, a valve seat having multiple seat orifices relative to which the valve metering slots are moved for metering the multiple fuel flows, and multiple fuel discharge paths for conducting multiple fuel flows to each of a plurality of fuel injection devices. Each fuel discharge path to each fuel injection device includes multiple upstream transversely spaced discharge passages and multiple downstream discharge passages nested longitudinally one inside the other with the inner downstream discharge passage aligned beneath its associated upstream discharge passage and another downstream discharge passage therearound being transversely displaced relative to its associated upstream discharge passage. A transverse discharge passage is provided inter-connecting each transversely displaced outer downstream discharge passage with its associated upstream discharge passage. Separately metered primary and secondary fuel flows can be thereby provided to each of a plurality of fuel injection devices, such as nozzles, spraybars and the like, connected to the assembly.
