摘要： This invention is an armature and an armature driving device in which the armature is rotated around its axis so as to inhibit uneven wear from occurring between the armature and a housing. That is, an armature which is slidably provided within a housing filled with fluid and which divides the inside of the housing into two fluid chambers is further provided with a communicating hole that enables the fluid to pass between the two fluid chambers. This communicating hole is formed such that the fluid passing through the communicating hole and out from the armature when the armature slides flows out at an angle to, and to the side of, a center axis of the armature.

摘要： A proportional solenoid valve for a high-pressure diesel pump of a motor vehicle has a housing and a solenoid with an armature movable in the housing. A bushing is provided, and a piston is arranged in the bushing. The armature acts on the piston for moving the piston in the bushing as a function of a current supply to the solenoid. At least one component is positioned between the bushing and the housing and is deformable in an axial direction of the piston so as to allow an exact adjustment of the position of the piston relative to the bushing.

摘要： A fuel system is disclosed in which high-pressure fuel pump with a prefeed pump is proposed, in which the fuel quantity pumped by the prefeed pump is distributed for cooling and lubrication purposes, via a continuously adjustable multiposition valve, to the pump elements of the high-pressure fuel pump or to the low-pressure region of the high-pressure fuel pump. The multiposition valve is controlled by the control unit of the engine. An advantageous feature of the high-pressure fuel pump of the invention is that depending on the operating state of the engine and of the high-pressure fuel pump, an optimal distribution of the fuel quantity pumped by the prefeed pump can always be accomplished. Moreover, the energy demand by the prefeed pump is reduced and its service life is lengthened.

摘要： A pumping system for a fuel injection system includes a body defining a high pressure pumping chamber, a plunger, a high pressure outlet, a high pressure fluid line connecting the pumping chamber to the outlet, a control valve along the fluid line, and a valve and restriction arrangement along the fluid line. The valve and restriction arrangement includes a restriction and a valve body. The valve body is movable between an open position in which fuel flow from the pumping chamber is generally unrestricted by the restriction and a closed position in which fuel flow from the pumping chamber is significantly restricted by the restriction to store energy in the pumping chamber. Advantageously, the high pressure restriction concept may be utilized in a pumping system for various types of rate shaping, including boot injection and square injection, in addition to pilot operation and post injection operations, and others.
