    摘要： The injector comprises a balanced metering servovalve for controlling a rod for opening/closing a nebulizer. The servovalve has a valve body having a control chamber provided with an outlet passage that is opened/closed by an axially mobile open/close element. The open/close element is made of a single piece with a bushing separate from an armature plate of an electromagnet. The bushing is coupled to a stem in an axially slidable way for closing an exhaust duct in communication with the outlet passage The open/close element is kept in a closed position by a spring that acts upon the bushing through an intermediate body connected thereto. The armature plate can be displaced with respect to the bushing between a flange of the intermediate body and a shoulder of the bushing, for eliminating the rebounds of the open/close element upon closing of the servovalve.

    摘要： An internal combustion engine for motor-vehicles, includes a system for variable actuation of the intake valves of the engine having a solenoid valve controllable between a closed condition and an open condition wherein it places a pressurized fluid chamber in communication with an exhaust chamber, with the aim of decoupling the intake valve from the respective tappet and causing the quick closing of the intake valve due to the respective return spring. The solenoid valve has a valve element with a cylindrical body having a first conical surface portion and a second conical surface portion. The conical surface portions are defined by the axially opposite ends of a circumferential groove formed on the valve element. The first conical surface portion cooperates with the valve seat. The other conical surface portion has an outer diameter substantially identical to the diameter of the annular edge defining the valve seat.

    摘要： The injector comprises a balanced metering servovalve to control a rod for the opening/closing of a nozzle. La servovalve has a valve body with a control chamber radially delimited by a tubular portion and fitted with an outlet passage that is opened/closed by an axially movable shutter. The servovalve is also integral with an axial stem, provided with a lateral surface, through which the outlet channel exits. The shutter is coupled to the stem in an axially sliding manner and, when it closes the outlet passage, it is subjected to substantially null axial fuel pressure. The outlet passage has a calibrated segment distanced from the shutter and close to a bottom wall of the control chamber. The calibrated segment is carried by an element fixed to the valve body in correspondence to an axial segment of the outlet passage.

    摘要： A fuel-injection system for an internal-combustion engine has at least one fuel injector with a fuel-metering servo valve provided with an open/close element, which is movable in response to the action of an electric actuator; and an electronic control unit which issues to the electric actuator two electrical commands, one for carrying out a pilot injection and one for carrying out a main injection; the two electrical commands being separated by an electrical dwell time such that the main injection starts, without solution of continuity with the pilot injection, when an open/close needle for carrying out fuel injections into a cylinder of the internal-combustion engine remains at a lift value in which the fuel flow rate is negligible; in particular, the second electrical command is issued during a rebound of the open/close element on the valve seat.

The servo valve has a valve body having a control chamber provided with an outlet passage that is opened/closed by an open/close element that is axially movable. The open/close element is separate from an armature of an electromagnet, and is slidable on an axial guide element for closing the outlet passage. The open/close element is held in the closing position by a spring acting through an intermediate body. The armature can be displaced with respect to the axial guide element between a flange of the intermediate body and a projection element of the guide member, for eliminating the rebounds of the open/close element upon closing of the solenoid valve.
