ABSTRACT:
A centrifugal fuel distributor including a drive shaft rotatably mounted within a housing having a distribution cavity. A sidewall of the distribution cavity defines a plurality of spaced-apart fuel outlets, and a hollow armature is biased radially outwardly from the drive shaft, so that a distal end of the armature is in sealing contact with an inner surface of the sidewall. During operation, pressurized fuel travels through a fuel passage in the drive shaft and through the hollow armature while the drive shaft is rotated, so that the distal end of the armature slides along the inner surface of the sidewall of the distribution cavity and sequentially distributes fuel to the plurality of fuel outlets. The fuel then passes from each fuel outlet to fuel injectors mounted in cylinders of an engine incorporating the fuel distributor. A timing rotor is secured to the drive shaft and signals the position of the armature as the drive shaft rotates to an actuator controlling fuel flow, so that the actuator allows the fuel passage to be replenished with pressurized fuel each time the hollow armature distribute fuel to a fuel outlet.
