    摘要: A high pressure fuel injection system includes a pump-type fuel injection nozzle assembly provided with a sliding control valve which admits pressurized fuel or opens a return channel. A pressure chamber situated near the end of the needle valve of the nozzle remote from its seat is connected via a bypass channel with a region downstream of the sliding valve for the purpose of exerting a hydraulic closing force on the needle valve. The pressure in the bypass channel is controlled by the motions of the sliding valve. Alternatively, the additional hydraulic pressure may be exerted on the needle by an intermediate piston.

    摘要: A speed governor for fuel injection pumps is proposed having a guide shaft guided in a cam plate to serve as the pivot shaft for a governor lever connecting an adjusting member and a supply quantity control member. The guide shaft is adjustable and guided appropriately by means of an adjusting lever so far as to form a variable-speed governor adapted to varying the full-load and maximum rpm. The cam plate is adjustable by a device by means of an operating parameter acting independently of the speed governor, for instance, the engagement of a cruising or overdrive gear in a manual transmission. Upon rotation of the cam plate, the guide shaft is displaced by a movement-coupling member into a position in which a minimum idling rpm is assured.

    摘要: A fuel injection device is proposed which has a free piston hydraulically driven by a pump piston and controlling the relieving of the pump work chamber. To this end, the free piston is embodied in two parts, comprising a control piston and a relief piston displaceable relative thereto and oriented toward the pump work chamber. The two pistons enclose between them a relief chamber, which at the end of supply can be made to communicate via a relief conduit with a chamber of lower pressure. This free piston is also usable with fuel injection pumps which supply the injection quantity via a long pressure line to the injection nozzles located on the engine; however, it is particularly advantageously usable with a pump/nozzle, in which the injection pump and the injection nozzle are combined into a single component.

    摘要: An injection instant adjuster for internal combustion engines is proposed, by means of which the mutual rotary position of an off-drive element relative to a driving element is variable at least in accordance with rpm. The injection instant adjuster includes at least two adjusting cams acting as the adjusting mechanism, which during their rotary movements, effected by control elements, control a "late" adjustment (.alpha.) of the instant of injection during a first partial rotation (.gamma.) which precedes the "early" adjustment (.beta.) controlled during the further partial rotation (.delta.). This is possible by means of a suitable selection of the outset position of an adjusting bolt. A detent in the adjusting curve, during which no adjustment takes place within a predetermined rpm range, is controllable at the transition between "late" and "early" adjustment by means of the spring sets comprising at least two adjuster springs, whenever the second adjuster spring is installed in the adjuster with initial stress, with the interposition of a spring plate and acting counter to the adjusting force of the control element.

    摘要: A fuel injection pump for internal combustion engines having an equal-pressure relief valve, which has a structure requiring little space when installed and is provided with a fastener element. The equal-pressure relief valve comprises a pressure valve body, onto which a beaker-shaped filler piece protruding into the interior of the pressure valve spring is placed. The structural unit comprising the pressure valve body and the filler piece containing the relief valve is held together, even when the pipe connector fitting or the pressure valve spring is removed, by means of the transit fastener element provided with a fastener ring. The invention is applicable both to single and series fuel injection pumps as well as to distributor injection pumps, particularly when space for installation is restricted.

    摘要: A fuel injection system is proposed for Diesel type internal combustion engines, by means of which the ignition conditions of a Diesel engine are kept optimal even during operation at high altitudes despite a reduced air charge. The system includes a fuel injection pump equipped with an injection timing adjustment apparatus which functions in accordance with rpm and a control apparatus functions in accordance with the air quantity supplied to the engine. By means of the control apparatus, a correction controlled in accordance with air pressure and therefore dependent on air quantity is superimposed on the change in the onset of the fuel supply controlled by the injection adjuster at least in accordance with rpm. When a hydraulic injection adjuster is used, the supply pressure of a control pump is increased by a correcting final control element of the control apparatus when the air quantity is decreasing in the direction toward an early adjustment of the onset of supply.

    摘要: A fuel control system to provide an excess fuel quantity during engine acceleration and including manifold pressure actuated control units. The pressure increase in one control unit is delayed by throttling, resulting in net differential control forces tending to increase the fuel supplied to the injection nozzles of the engine injection system while the manifold pressure is rising.
