摘要： Method for piloting electromagnetic actuators for the control of the valves of an engine; each electromagnetic actuator is provided with at least one respective electromagnet, which is piloted by a common piloting device by means of the supply of an electric current wave which has two, initial and end control portions in which the intensity of the electric current varies rapidly and an intermediate maintenance portion in which the intensity of the electric current remains substantially constant; the method consists of supplying respective electric current waves cyclically to the electromagnets in order to control the valves according to the drive point, and to vary at a control portion of each wave the value of the intensity of the electric current supplied during the portions of maintenance of the other waves in order to limit the variation of the quantity of electric charge distributed overall by the piloting device.

摘要： An electromagnetic actuator for the control of the intake or exhaust valves of an internal combustion engine, in which an oscillating arm has a first end hinged on a fixed support and a second end in abutment, directly or via the interposition of a strut, on the upper end of the stem of the intake or exhaust valve, two electromagnets being provided in order to move, on command, the oscillating arm so as axially to displace the valve between a closed position and a position of maximum opening, a first and a second elastic member being provided to maintain the intake or exhaust valve respectively in the closed position and in the position of maximum opening, by exerting on the valve axial thrusts contrary to one another; in the balanced position, the two elastic members are adapted to maintain the valve in an intermediate position between the closed position and the position of maximum opening.

摘要： A valve comprising a plunger controlled by an electromagnet and in turn controlling fuel flow through an injection orifice; the plunger being defined by a cylindrical lateral surface mating in sliding manner with a corresponding cylindrical guide surface of a seat formed in the valve body. According to the present invention, the barycenter of the plunger lies in a plane of the valve perpendicular to the valve axis, and the distance between which plane and the mid plane of the cylindrical guide surface is less than 2 mm.

摘要： The present invention involves an electromagnetically actuated fuel atomizing and metering valve. The valve has a metal body housing an electromagnet, a core, and an injection nozzle. The injection nozzle has at least one fuel injection orifice passage controlled by a movable shutter member fixed to an armature. The shutter member controls the passage of fuel through the injection orifice and comprises a disc delimited by a cylindrical outer lateral surface which has substantially the same diameter as the outer surface of the armature. The disc is connected to the armature by laser welding between the upper circular edge of the disc and the lower circular edge of the armature.
