Abstract
An internal-combustion engine includes a three-way, three-position control valve with an inlet communicating with a pressurized-fluid chamber and with a hydraulic actuator of an intake valve, and two outlets communicating, respectively, with the actuator of the other intake valve and with said exhaust channel. The control valve has a first position, in which the inlet communicates with both of the outlets, a second position, in which the inlet communicates only with the outlet connected to the actuator of an intake valve and does not communicate, with the outlet connected to the exhaust channel, and a third position, in which the inlet does not communicate with the two outlets. The control valve has an electric actuator supplied only at three different values of electric current to bring the valve into the three positions.
