    摘要: A fuel injection pump in which the quantity adjustment member has a travel limitation in the form of an adjustable stop, which is adjusted in accordance with the displacement of an adjusting piston in accordance with a contour defined on the adjusting piston. The displacement of the adjusting piston is effected with the rpm-dependent pressure of the suction chamber of the fuel injection pump, and the work chamber preceding the adjusting piston can be uncoupled from the suction chamber via a throttle. The maximum displacement of the adjusting piston is limited by a stop which is adjustable in accordance with charge pressure or by a pressure control device by means of which the pressure in the work chamber can be adjusted or limited.

    摘要: A fuel injection apparatus particularly suitable for high-powered engines, in which the pressure chamber of the fuel injection valve or valves is relieved of pressure during the pauses between injections by means of a correspondingly controlled obturation mechanism so that, when the valves are not tight, the undesirable injection of fuel during the pauses between injections is substantially prevented.

    摘要: A fuel injection pump which has a shutoff device for the fuel supply to the pump work chamber, comprising a magnetic valve, which controls an intake bore to the work chamber of the fuel injection pump. The fuel injection pump further has a relief conduit, which is connected by an annular slide on the pump piston with the suction chamber in order to terminate the effective supply stroke of the pump piston. In order to assure reliable shutoff of the fuel supply to the pump work chamber, a check valve is further disposed in the connection between the pump work chamber and the suction chamber, which check valve is closed, during the intake stroke of the pump piston, with the collaboration of the pressure drop from the suction chamber to the pump work chamber.

    摘要: A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up. Various embodiments are presented.

    摘要: A fuel injection pump is proposed, which has a centrifugal governor disposed in the suction chamber of the fuel injection pump, the governor having a sleeve displaceable on a piston, and a pressure chamber enclosed in the interior of the governor sleeve, the latter being defined by the end face of the piston. By means of a relief line of the pressure chamber which is opened in the offset position of the governor sleeve, the restoring force on the centrifugal governor is increased during starting by the amount of the pressure difference appearing at the governor sleeve. Beyond a predetermined adjustment of the governor sleeve, the relief line is blocked, so that the governor can function unhindered within the normal operational range. The hysteresis thus resulting upon the shut-off of the increased starting quantity improves the behavior of the engine as it runs up to operational speed.

    摘要: A fuel injection pump is proposed in which the quantity adjustment member has a travel limitation device in the form of an adjustable stop, which is adjusted in accordance with the displacement of an adjusting piston in accordance with a contour formed in the jacket face thereon. The displacement of the adjusting piston is effected via rpm-dependent pressure of the suction chamber counter to the force of a restoring spring and counter to a pressure which can be established with the aid of a pressure control valve in accordance with engine operating parameters. The adjustment of the stop is thus effected with the high work capacity of the suction chamber pressure, and the limitation of the adjustment is attained with the aid of the modulated pressure diverted from the suction chamber pressure.
