摘要： A perfected fuel injector comprising a plunger for controlling fuel passage between an injection chamber and at least an injection orifice formed in an injection nozzel; and an electromagnetic fuel metering valve for controlling fuel passage through a drain orifice between a control chamber, supplied with fuel under pressure, and a low-pressure chamber, so as to reduce to a given value the pressure of the fuel inside the control chamber and so displace the plunger. Pressurized fuel is supplied to the injection chamber and control chamber by means of a single fitting connected to a supply pipe and coming out inside a supply orifice formed in the injector body and communicating with the control chamber and with a duct supplying fuel to the injection chamber and comprising an annular chamber and a radial hole formed in a sleeve housed in a hole on the body.

摘要： The subject of the invention is an improvement in the pilot valve which is adapted to control the passage of fuel through a discharge aperture which communicates with a control chamber with which the device is provided; fuel is supplied under pressure into this control chamber and is discharged through the first mentioned discharge aperture to control the opening of a shutter needle with which the device is provided for the purpose of injecting a suitable quantity of fuel through at least one injection orifice. According to this improvement the armature of the pilot valve substantially comprises a rod which traverses an axial hole in the core of an electromagnet. The first end of the rod is fixed to the armature. A stop member, the position of which is adjustable with respect to the body of the device, is adapted to constitute an abutment for the second end of the rod. A ball is interposed between this second end and the stop member. A threaded ring nut presses against the elongate body housing the needle so as to fix the valve body and resist the force on the valve body exerted by the fuel under pressure.

摘要： An electromagnetically-controlled fuel injection valve for diesel engines includes an electromagnetic metering valve which controls communication between a control chamber supplied with fuel under pressure through an inlet hole, and a discharge hole. The solenoid metering valve includes a ball obturator movable in a cavity of the body defined by two annular valve seats of which the first defines the discharge hole and the second communicates with the inlet hole. The cavity is in communication with the control chamber through lateral passages. The ball obturator is kept in a closed position against the second seat by means of an electromagnetically-operated axial push rod.

摘要： A fuel injector for an internal-combustion engine comprises an injector body and an injection-control valve, which in turn comprises: an open/close element; an elastic thrust element for pushing the open/close element; and a solenoid actuator, which can be actuated for exerting an action countering the thrust exerted by the elastic element. The solenoid actuator is formed by a monolithic assembly obtained in a mould, in which there is injected, on a core and a coil coupled to one another, a plastic material, which defines, once it has solidified, a body for insulation of the core from the injector body and which forms, once it has solidified, a monolithic assembly with the core and the coil.

摘要： A metering servovalve for a fuel injector of an internal combustion engine has an electro-actuator and a fixed valve body, which defines a control chamber communicating with an inlet and with an outlet channel. The outlet channel has at least one calibrated restriction and exits through the lateral surface of an axial stem, on which a sleeve slides, in a substantially fluid-tight manner, to open/close the outlet channel and so vary the pressure in the control chamber. The outlet channel is closed by an end portion of the sleeve that is elastically deformable in a radially outward direction, under the thrust of the fuel pressure, to increase the diameter at which the seal against the valve body is formed, with respect to a non-deformed state, and to generate an axial unbalancing force on the sleeve upon opening when the outlet channel is closed.

摘要： An injector with an adjustable-metering servo valve is provided. The injector has a shutter actuated by an armature of an electromagnet. The armature is mobile for an opening stroke defined by a surface of the core of the electromagnet, which is fixed in the casing by a ring nut and a hollow support of the core. The hollow support has a first contact surface that acts on a flange of the core. Set between the surface and a shoulder of the casing is a shim. An annular projection, having a second contact surface, is set between the surface and a shoulder of the casing. The second contact surface is contained at least in part in the area corresponding to the first contact surface so that the stroke of the armature is adjusted by plastic deformation of the shim or of the surface of the core.

摘要： The fuel injector comprises a hollow casing, fixed on which is a nozzle having a nebulizer for the fuel under pressure, a needle axially mobile for opening and closing the nebulizer by means of a first end thereof, and a control rod, substantially coaxial with the needle and in direct engagement therewith. The needle is normally pushed into a closing position of the nozzle by the fuel under pressure acting on the rod, aided by a compression spring, which acts on the needle through a sleeve that is in axial engagement with a portion of the rod. The sleeve further comprises a surface designed to engage at the front and directly one end of the needle. The spring engages another surface of the sleeve so as to transmit its action directly onto the needle.
