摘要： The invention is directed to a method and arrangement for controlling a self-igniting internal combustion engine. The arrangement includes at least one measured-value sensor, electronic control unit for forming a quantity signal for metering fuel, and a control unit for driving individual actuators for each cylinder. The actuators determine the quantity of fuel injected by the pump elements into the cylinders. 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.

摘要： A fuel injection apparatus for internal combustion engines in which beyond a predetermined remaining stroke during the supply stroke of the pump piston, a relief conduit is opened via a control edge. The same control edge closes the relief conduit once again during the intake stroke. During the subsequent effective intake stroke, the quantity of fuel to be injected upon the following compression stroke is metered by means of the electrically actuatable valve. The magnetic valve here is already opened before the closure of the relief conduit by the control edge, so that in the opening phase of the relief conduit, the pump work chamber of the fuel injection apparatus is flushed. In this manner, precise metering of the quantity of fuel to be injected is attained.

摘要： A fuel injection pump for internal combustion engines, in which beyond a predetermined remnant stroke during the supply stroke of the pump piston a relief conduit is opened via a first control edge and the remaining fuel pumped by the pump piston is pumped into a reservoir connected there. During the subsequent intake stroke, the diverted fuel is pumped back into the pump work chamber of the pump piston, until the first control edge again closes the relief conduit. During the subsequent intake stroke of the pump piston, in particular at the bottom dead center position of the pump piston, the relief conduit to the reservoir is once again opened by a second control edge, and then a complete relief of the reservoir is attained. It is during this phase that the metering of the fuel to be injected during the next supply stroke of the pump piston also takes place, via a magnetic valve. With an apparatus of this kind, it is advantageous that the fuel quantity per supply stroke of the pump piston that is actually to be injected can be metered exactly by means of a magnetic valve under pressure conditions that remain constant despite variable opening times.

摘要： A drive device for a tape recorder by which the recording tape is drawn off one spool by means of a capstan, and is wound-up on another spool, which is driven over a friction coupling by a motor with a speed not substantially above the highest required winding speed, with a drive device driven by the same motor, the drive device for the purpose of fast rewinding being selectively coupleable on one of the two spools. The two drive gears are arranged on a swingable carrier arm driven continuously in oppsite working directions by a stationarily arranged motor via a belt. By swinging the carrier arm in opposite operating directions out of a neutral center position, the drive gears are coupleable from time to time with one of the spool-carrying winding spindles for fast rewinding. One of the drive gears, which is coaxially seated over a friction clutch, is connected with another drive gear of smaller diameter, the latter in a neutral center position of the carrier arm being able to be brought into engagement with still another drive gear by means of an axial movement of one of these other drive gears, said still another drive gear being coaxially seated on the winding spindle which carries the spool which in the play-operation serves as the winding-up spool.

摘要： A fuel injection pump for internal combustion engines that has a pump interior and a final control element chamber, separated from it, the latter having an electric final control element for actuating a quantity adjusting device that determines a fuel injection quantity, parts of the final control element from which a control variable for the injection quantity is derived and which thereby serves as a material measure, are to be protected from the influence of fuel. By means of a jet pump through which a permanent propulsive flow flows and which is part of a flow conduit, the static pressure at the intake bore of the jet pump that communicates with the final control element chamber is lowered, and this negative pressure is utilized for evacuating the fuel entering the final control element chamber in the form of a leakage flow along the bearing of a control shaft. This arrangement is particularly suitable for high-pressure injection in Diesel engines, to attain highly accurate fuel metering that is stable over a long period of time.

摘要： 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.

摘要： A fuel injection pump is proposed in which over a first portion of the supply stroke of the pump piston fuel for the main injection is pumped via a distributor line and a distributor groove into one at a time of a plurality of fuel injection lines. In a second, remaining portion of the pump piston supply stroke, on the same cam flank, fuel is then pre-stored in a reservoir, controlled by a first electrically controlled valve and a second electrically controlled valve and by one of a plurality of longitudinal control grooves, which fuel subsequently, before the beginning of the next main injection determined by the closure of the first electrically controlled valve, is pumped via a second distributor line into the next succeeding injection line.
