摘要： An electromagnet housed in a skirt pressed on to a cap integral with the in conduit of the control valve. The skirt presents two shoulders separated by a distance greater than the height of the core of the electromagnet and on which the core and the cap rest. At least one Belleville washer between the core and the cap holds the core elastically on the respective shoulder and detached from the cap. A retaining ring coaxial with the washer is also provided for sealing the fuel flowing in an axial hole on the core and in the drain conduit.

摘要： A control valve for an injector comprising a valve body having of a control chamber connected to a drain conduit via a hole terminating at a flat surface of the valve body. The plunger of the valve consists of a plate housed in a seat, the bottom wall of which arrests the travel of the plate after a travel "b". This is controlled by the armature of an electromagnet, which armature presents a rod arrested directly by an adjustable stop after traveling a distance "a" greater than travel "b". The opening and closing time of the valve is therefore unaffected by wear on the stop of the armature. The rod of the armature is in one piece with a stem activating the plate, and with a threaded portion screwed to the armature.

摘要： A valve controlled by an electromagnetic metering valve comprising a head ving a control chamber, a supply conduit, and a drain conduit. The head also presents a cavity communicating with the supply conduit and in which a portion of the moving element for closing the injection orifice slides in such a manner as to choke the supply conduit during injection. The supply conduit communicates with a receiving chamber located between a seat in the body of the valve and the outer surface of an appendix on the head; and the moving element is pushed into the closed position by the combined action of the pressure at each end, and a spring located close to the injection chamber.

摘要： The body of a control valve is housed inside the hollow body of an injectory means of a fluidtight connection comprising a pair of precision ground mating surfaces, and a sealing ring compressed between a further two surfaces of the bodies adjacent to the aforementioned pair of surfaces. The ring may be made of rubber, may be fitted between two cylindrical surfaces, and is also pressed by the fuel on to a shoulder of the valve body. Alternatively, the ring may consist of a soft iron washer pressed axially between a flange on the valve body and a surface of the hollow body.

摘要： The control valve of an injector comprises a plunger and a valve body having an axial control chamber connected to a drain conduit via a hole. The hole terminates at a flat surface of the valve body, which surface is perpendicular to the operating direction of the actuator of the plunger. The plunger consists of a pad element having a flat face engaging the surface of the valve body, while the opposite face may be flat or spherical, and is engaged by a complementary surface on the end of the actuator.

摘要： The pump comprises a plurality of cylinders (4) disposed radially in a star formation around a shaft (5) with an eccentric (6) in a body (2, 3) formed by first and second members (2, 3) joined together by bolts (13). Each cylinder (4) is clamped in position between the first and second elements (2, 3) of the body between a pair of the said bolts (13). The facing surfaces of each cylinder (4) and of at least one (3) of the members (2, 3) of the pump body are spaced in correspondence with the central portion of the cylinder (4) in which is formed the chamber (9) in which the associated piston (10) is movable, so that the contact between the cylinder (4) and the at least one member (3) of the body (2, 3) of the pump is limited to surfaces outside the central portion of the cylinder (4).

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.
