Abstract
In order to automatically adapt the control of an ultrasonic fuel-injection system or other system in which fuel delivery from nozzles is normally controlled by varying the mark/space ratio of energising current supplied to the nozzles, to variation of ambient pressure, a pressure-regulating unit is provided in a line leading from a source of fuel under pressure to the nozzles through a manually adjustable throttle valve and is arranged to maintain the pressure difference between the inlet and outlet of this series arrangement constant for any given ambient pressure P1. An altitude compensator comprising a spring-expanded vacuum capsule and a mechanical transmission is provided for varying this pressure difference in proportion to the ambient absolute pressure P1.
