摘要： A fuel quantity measuring apparatus, preferably for a Diesel engine, is proposed in which the course of the fuel pressure is evaluated. A specialized pressure gradient of a first polarity marks the onset of supply or injection, and the maximum of the pressure gradient of the other polarity represents the end of injection or supply. The question of which designation prevails, whether injection onset and end or supply onset and end, is determined by the measurement location, that is, whether it is in the direction of the injection valve or in the direction of the supply element of the fuel supply pump. The injection quantity, for example, may be determined via the integral of the pressure during the metering period. It is recommended, when a piezoelectric pressure receptor is used, that a resistor-capacitor element be switched parallel thereto.

摘要： 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.

摘要： A fuel injection pump for internal combustion engines comprising a pump housing, a distributor piston guided axially and rotatably, a rotating drive shaft supported in the pump housing, a transmission coupling the drive shaft to the distributor piston and a claw clutch and an eccentric disk rolling on a roller race with cams, and a lubricating oil circulation loop, which has a lubricating oil feed line discharging into a lubricating oil groove and a lubricating oil return line that returns from the transmission chamber which is partly filled with lubricating oil. To assure adequate supply of lubricating oil to the heavily loaded drive faces of the claw clutch, there is a flow lubricating oil through the drive shaft from the lubricating oil groove on into the claw clutch; via lubricating oil openings in at least those claw faces of the claw clutch that transmit a torque, the flow emerges into the transmission chamber.

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.
