Abstract: A fuel injection pump has a pump plunger (13), which is driven by a drive shaft (15) via a cam gear (14) at least in an axial stroke movement and in so doing generates a fuel injection pressure in a pump work space (16), and a magnet valve (30) blocking or releasing the pump work space (16) relative to a relief duct (26). The start of delivery of the pump plunger is determined by the closing of the relief duct (26) and the end of delivery of the pump plunger (13) is determined by the release of the relief duct (26). To prevent the so-called jumping off of the plunger in the cam gear (14), the magnet valve (30) is controlled after the end of delivery in such a way that a residual pressure lying below the injection pressure is built up in the pump work space (16) until the top dead center point is reached (FIG. 1).

Abstract: A fuel injection pump in which the injection onset is varied by means of an injection adjuster, which has a two part adjusting piston acted upon by a hydraulic control pressure, which piston is adjustable counter to a restoring spring and by means of a bolt, engages the cam drive of the fuel injection pump in order to adjust the injection onset. To reduce the highest pressure in the high-pressure chamber of the fuel injection pump and to form the course of injection pressure, the adjusting piston is embodied in two parts, with a first piston that is adjustable relative to the second piston counter to a compression spring and the second piston is connected with the bolt. This makes possible a deflection motion of the piston relative to the second piston and a reduction in the pump piston stroke speed.

Abstract: A control device for varying the supply onset of a fuel injection pump, in which the supply rate at the lower full-load point is increased without overloading the pump at the rated capacity point. A control of this kind is effected by the use of a deflection piston as well as by use of a prestressed check valve. Regulation serving the same purpose can be achieved with the aid of an element pressure sensor and two magnet valves. The control device is intended for use in an internal combustion engine.

Abstract: The invention relates to a method and arrangement for preparing a fuel-metering signal M for a diesel engine starting with measured variables such as accelerator pedal position, rotational speed, lambda, exhaust gas temperature or torque. A fuel quantity request MW is pregiven in dependence upon the position of the accelerator pedal. This quantity request MW is supplied to a minimum selector together with a second signal. The output signal M of the minimum selector, in turn, determines the metered fuel. The second signal derives from a precontrol characteristic field 50 in dependence upon the speed. The output signal of the precontrol characteristic field MV is influenced by the controller output signal MR in specific operating conditions.

Abstract: It is possible in a simple manner, especially in distributor injection pumps, to attain quiet combustion in the idling range of a Diesel engine, without modifying the basic construction of the fuel injection pump by shifting the injection pumping to the last portion of the stroke of the cam driving the pump piston of the fuel injection pump for idling, by means of an injection onset adjusting device, in combination with a determination of injection duration via the closing phase of an electrically controlled valve that relieves the pump work chamber.

Under specific conditions, a corrective unit is activated which determines corrective values specific to the cylinders for making the cylinders equal. The open-loop control unit applies the metering signal to the actuators in dependence upon the quantity signal and the corrective values.

Abstract: The invention is directed to a method and an arrangement for controlling the fuel injection in a high-pressure fuel pump. Magnetic valves determine the fuel quantity to be injected into the engine. The magnetic valve is controlled during the pumping phase of the pumping element in such a manner that first a preinjection and then a main injection is carried out. In specific operating conditions, the control apparatus determines the duration of the drive pulses for the magnetic valve at which a preinjection just takes place. With the duration of the drive pulses as a basis, the control apparatus forms compensating signals for the drive pulses which effect preinjection and stores the same.

Abstract: A record player in which a magazine is provided with compartments for storing a number of rigid and flexible disk-shaped recording media. For playing the disks, they are removed only to an extent necessary for the disk drive to engage bores of the disk. Each compartment has a bottom with a semi-circular recess at a side of the magazine from which the recording media are removed for being played. This recess has a diameter that is substantially longer than the diameter of the respective disk to be played, so that the disk can rotate freely while being played. Each compartment, furthermore, as a storage recess above the semi-circular recess for storing the disk. To play the disk, the latter is lowered from the storage recess into the semi-circular recess, but the lowering of the disk is such that the disk will not contact the bottom of the semi-circular recess, so as to allow free rotation of the disk within the semi-circular recess.

Abstract: A fuel injection pump for internal combustion engines having an electromagnetic final control element, which in order to adjust the end or onset of injection engages a control slide, located in the pump interior. Via a control shaft, the final control element chamber is hermetically sealed off from the pump interior in order to keep water contained in the fuel from reaching current-carrying parts of the final control element. As a result, fluid communication exists only via the bearing gap of the slide bearing of the control shaft and the bearing gap functions as a throttle. The throttle forms a water separator, which further reduces the concentration of water in the already small quantity of fuel reaching the final control element chamber through the throttle.
