In a single device for controlling electro-injectors and electrovalves in an internal-combustion engine, a first control circuit for each electro-injector, a second control circuit for each electrovalve, and a timing circuit, supplying timing signals to the first and second control circuits. In the second control circuit, switches selectively connect the respective electrovalve to a first voltage source in certain given operating conditions, and to a boosted voltage source, constituted by a capacitor for accumulation of energy, in certain other given operating conditions. In this way, part of the electrical energy accumulated in the electrovalve during its normal actuation is transferred to the capacitor, thus causing the latter to be recharged.
