Abstract
An actuator composed of: a) a solenoid (1) with a ferromagnetic nucleus (2) which slides inside it and is combined with a rod (3) appropriate for interacting with the turbocharger's (5) pilot point (4) and provided with a sensing system (7) of the position of the ferromagnetic nucleus (2) in the solenoid (1); b) and an electronic circuit which:—on the way in receives at least the signal from the engine's electronic control unit and the feedback signal, connected to the position of the ferromagnetic nucleus (2) of the solenoid (1);—on the way out it distributes the electric current, connected to the said entry signals, with which it feeds the same solenoid (1).
Claims15
An electromechanical actuator for the regulation of the turbocharger of internal combustion engines, characterized by the combination of:
- a) an electromechanical group comprising a solenoid (1) equipped with a sliding ferromagnetic nucleus (2) supplied with a rod (3) intended to interact with the pilot point (4) of the turbocharger (5) and furnished with a sensing system of the position occupied by the ferromagnetic nucleus (2) in the solenoid (1);
- b) an electronic circuit which:—on the way in receives at least the signal from the engine's electronic control unit and the retroaction or feedback signal tied to the position of the ferromagnetic nucleus (2) in the solenoid (1);—on the way out it distributes the electric current connected to the entry signal and with which it feeds the solenoid (1) generating the magnetic field.
