摘要： The metering valve is controlled by an electromagnet having a fixed core, aoil, and an armature. The core is formed by pressing and subsequently sintering a mixture of powdered ferrous material and an epoxy binder; and presents a low magnetic hysteresis and low parasitic currents, so that, for a given energizing current, a greater magnetic force is achieved and more rapidly, and, for a given magnetic force or maximum operating frequency, the core and/or coil may be made smaller.

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： The pump (7) is provided with a body (16) having a compartment (17), and with at least one pumping element (13) that moves in a cylinder (12) in communication with the compartment (17), to raise the pressure of the fuel. The pump (7) comprises fluid-supply means (14, 22) for delivering the fuel to the pumping element (13), and an inlet mouth (26) made in the body (16) and supplied with the fuel coming directly from an external source (2). The inlet mouth (26) is fluidically connected to the compartment (17) to supply it with the fuel in order to lubricate and/or cool the pump (7) itself. Set between the inlet mouth (26) and the compartment (17) are: a non-return valve (33) to prevent in any case the pumping elements (13) from sucking the fuel from the compartment (17) of the body (16); and a flow regulator (29′), which allows an amount of fuel to pass such as to enable proper lubrication and cooling of the compartment (17) and of the parts present in the compartment (17). The fluid-supply means (14, 22) comprise at least one further inlet mouth (24) made in the body (16) and fluidically connected with the pumping element (13) by means of pipes (9).

摘要： The metering servovalve (7) includes a valve body (8, 30), a shutter (45), and an electromagnet (15), and is housed inside a casing (2) of the injector (1). The electromagnet (15) activates a movable armature (16) performing a travel defined by a stop member (19) carried by the electromagnet (15), which is fixed inside the casing by a threaded ring nut (40) with the interposition of at least one deformable shim (48). The ring nut (40) is screwed to a predetermined tightening torque to a thread (46) on the casing (2) to elastically deform the shim (48). And the shim (48) is defined by a metal ring with, for example, an L-, C-, S-, Z- or Σ-shaped cross section.

摘要： A fuel injector has a fuel inlet, and a metering valve which is activated by an electromagnetic actuator to open and close an injection nozzle; the metering valve has a control chamber communicating with the inlet and defined by an end wall, in which is formed an outlet hole closed by a shutter moved along an axis by the actuator; the end wall and the shutter are defined by respective parallel, facing surfaces which rest against each other to compress the film of fuel issuing from the hole during closure by the shutter, and which have channeling formed about the hole to generate, in use, a counterpressure for the outflowing fuel.

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.
