Abstract: In order to control fuel flow at a fuel delivery point for auxiliary power units, and for other low fuel flow applications, an altitude-sensitive fuel flow control device (10) includes a fuel inlet (12) in communication with a fuel source and a fuel outlet (14) in communication with a fuel combustor. The device (10) includes an axially extending rod (16) having a metering surface (22) intermediate the ends (24, 26) thereof which may be located in various positions relative to a fuel flow path (18a, 18b, 18c, 18d, 18e) extending from the fuel inlet (12) to the fuel outlet (14) by axial movement of the rod (16) which varies fuel flow within a preselected range of altitude-dependent fuel flow rates.
