Patent ID: 7117852

Claim:
A device for controlling electro-injectors and electrovalves in an internal-combustion engine, said device comprising a first control circuit for each electro-injector and a second control circuit for each electrovalve; wherein each first control circuit comprises a first input terminal and a second input terminal, configured to be connected, in certain given operating conditions, to a first source of electrical energy supplying a first voltage (V BATT ), and, in other given operating conditions, to a second source of electrical energy, supplying a second voltage (V BOOST ) higher than the first voltage (V BATT ) and comprising energy-accumulation means, a first output terminal, and a second output terminal, said terminals being configured to be connected, in use, to the respective electro-injector, and first switch means configured to connect the respective electro-injector to said first source of electrical energy in certain given operating conditions and to said energy-accumulation means in certain other given operating conditions; and wherein each second control circuit comprises a first input terminal and a second input terminal configured to be connected, in use, to said first source of electrical energy, a first output terminal and a second output terminal, configured to be connected, in use, to the respective electrovalve, and second switch means, configured to connect the respective electrovalve to said first source of electrical energy in certain given operating conditions; said device being characterized in that said second switch means are further configured to connect the respective electrovalve to said energy-accumulation means in certain other given operating conditions, for transferring the electrical energy accumulated in the electrovalve to said energy-accumulation means.
