L'invention est notamment applicable à un injecteur automobile et permet d'obtenir un dispositif de pilotage à la fois simple et peu coûteux.
The invention relates to an actuating device (1), provided with an actuator having an actuated part and an electrical control member (L1), a topology control electronics (4) of the actuator comprising a circuit bridge (5) with a DC source (6) between the first and second terminals of the circuit (51, 52), the electrical control member being connected between the third and fourth terminals of the circuit (53, 54) having a switch connected between the first and third terminals (I1) and a switch connected between the second and fourth terminals (I2) provided with a switch control device, the circuit in this bridge further comprises a first diode (D1) connected between said first and fourth terminals and a second diode (D2) connected between said second and third terminals. The invention is particularly applicable to an auto injector and provides a control device that is both simple and inexpensive.
