ABSTRACT:
An acceleration limiter is disclosed which includes a hydraulic accumulator (10) with a piston (10a), a spring, (10d) and a chamber 10b) for receiving the pressure Pi residing in the fuel supply circuit (3) from a point P1 in the supply circuit (3) located upstream from the injectors (2). Another chamber (10c) of the accumulator (10) is connected by a tube (11) to the outlet of the compressor (1a). This limiter makes it possible to absorb peaks in fuel flow resulting from sharp maneuvers on the throttle level with the same effectiveness despite variations in Pi, in particular with the altitude of the airplane.
