A rotor disk comprises a plurality of circumferentially distributed hooks, the set of hooks defining an annular groove adapted to cooperate with at least two flange sectors. At least one of the hooks comprises a second element through which a recess is formed which opens up at each of the transverse flanks of the second element and at the internal peripheral surface of the second element.

Rotor disk including a plurality of hooks

Hydromechanical regulator for controlling the flow of fuel injected into a turbomachine by means of a fuel feed unit (), comprising a tachometric balance () having a beam consisting of two arms (), which beam can move about a pivot pin () under the action of at least a first force Fapplied by a drive rod () of the fuel feed unit via a first elastic member (), and a rod () associated with a drive piston () for applying, via a second elastic member (), a force Fopposing the first force Fto the beam of the balance so as to cause the fuel feed unit to open further during the transition from a first engine acceleration law to a second engine acceleration law.

Regulator feeding control with two flow rate laws

A fuel metering unit in a turbomachine is connected between a high pressure pump which draws fuel from a fuel tank and a plurality of fuel injectors disposed in a combustion chamber of the turbomachine, the unit comprises a meter which receives the fuel for injection from a regulator valve at a pressure Pand delivers it at a pressure Pto said plurality of injectors via a stop valve, said regulator valve serving to recirculate fuel back to said high pressure pump as a function of the pressure difference between pressures taken directly from the terminals of the meter and injected into two end inlets of the regulator valve.
