摘要： An on-off valve is connected between a high-pressure pump and a low-press pump and is sized to be rapidly activated during the cranking stage of an internal combustion engine. After actuating the on-off valve, surplus fuel is drained into an inner chamber of the high pressure pump. A solenoid valve is further provided between the low-pressure pump and the on-off valve to automatically cut off the supply of fuel to the on-off valve in the event of an engine failure. The apparatus is beneficial to reduce variation in the fuel supply of the low pressure pump during engine start-up and steady-state operation.

摘要： The injector has a hollow body carrying a nozzle, and a metering valve hag a valve body housed in a cylindrical seat of the hollow body. The valve body has a distribution cavity for distributing high-pressure fuel to a control chamber of the valve, whereas the seat communicates with a cavity at atmospheric pressure and in which the control rod slides. The sealing device has an annular seal, which is compressed between two shoulders carried by the surface of the seat and by an outer surface of a portion of the valve body so as to provide for redundant sealing between the two surfaces.

摘要： The metering valve has a ball shutter for a conical seat over a discharge nduit, and an electromagnet for controlling an armature; a stem of the armature has a flange, is guided by a fixed sleeve, and is pushed by a spring to keep the ball in contact with the conical seat; provision is made, between the flange and the ball, for a decoupling joint in the form of a plate having a flat surface engaging the flange and a spherical concavity engaging the ball to center the ball on the conical seat; and the diameter of the concavity is slightly larger than the diameter of the ball to reduce the pressure between the mutually engaging surfaces of the concavity and the ball.

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.
