Abstract (en)
[origin: EP1624246A1] The valve has a tachometric balance (20) with a beam having arms (24, 26) movable around a hinge pin (22) based on a force applied by a control rod (18) of a fuel distributor through a compressed spring (28). A rod (36) is associated to a control piston (38) for applying a force, opposing to the former force, on the beam through a compressed spring (40) to open the distributor during passage from one acceleration law to another law. An independent claim is also included for a turbo machine having a hydraulic control valve.
