摘要： A fuel injection pump for internal combustion engines having a pump piston defining a pump work chamber and having control of the injection quantity by the opening, during the compression stroke of the pump piston, an axially displaceable regulating slide disposed about the pump piston, and of a relief conduit extending in the pump piston and discharging into the jacket face of the pump piston. Upon the opening, the relief conduit discharges into an outflow conduit provided between the pump piston and the regulating slide; at the onset of the opening stroke this conduit is fully opened, and during the course of the stroke it is throttled.

摘要： A fuel injection pump which has an adjusting piston for the purpose of injection instant adjustment. The adjusting piston has opposite ends defining respective work chambers. The work chambers are supplied with fuel under rpm-dependent pressure from a suction chamber of the fuel injection pump, via respective throttles, and are relieved via respective outflow lines. The outflow cross sections of the outflow lines are controlled in complementary fashion by a control slide of a control valve. The control slide is exposed to a modifiable control pressure derived from the rpm-dependent pressure, and for the peripheral conditions of a cold engine and rpm of the engine below a threshold rpm, the maximum controlled pressure is established by means of a third control valve.

摘要： An apparatus for generating a fuel quantity signal in an injection pump is proposed, which is provided with a pump piston deflected by a cam disk which aspirates fuel out of a fuel inlet conduit provided with a magnetic valve and expresses it into a supply line. The metered fuel quantity is obtained on the basis of a metering onset signal and an end-of-metering signal, the first being generated by a position-sensor apparatus cooperating with the pump piston and the second being derived from the voltage applied at the magnetic valve.

摘要： A tape recorder with a motor-containing-drive device for normal forward running (record or playback) and for fast rewinding of the recording tape, and a carrier plate on which the magnetic heads are arranged. The carrier plate is displaceable in its plane with the corresponding drive device of the tape by operating elements for setting of the operating modes "record" or "playback," whereby by the displacement of the carrier plate into its operating position, a switch, which sets the motor of the drive device in operation, is closed and by which the magnetic heads are brought into engagement on the recording tape. The operating elements for the fast rewinding are set for a displacement of the carrier plate however only over a portion of its displacement path. The switch for the motor current is coupled with the carrier plate such that it closes with the displacement of the carrier plate over this portion of its displacement path in the direction of the operating position of the carrier plate.

摘要： A tape recorder in which a counter indicates the tape length traversed in the recorder. The counter may be returned to an initial position by a manually operated element. A switching unit for shutting off the drive for the tape, is coupled to the counter so that the drive for the tape is shut off when the counter has returned to its initial position. The counter, furthermore, may be set to a pre-initial position ahead of the first-mentioned initial position by an amount of tape length which corresponds at least to the length of a dead portion of the tape, on which no recording or playback is possible. The recorder is also provided for resetting the speed of the tape from normal speed for recording or playback, to fast speed in the forward and rewind directions. The shutting off of the drive may be operated so that it becomes ready to function only when the fast forward setting is made. The counter may have numbered dials mounted on a common axis and bearing the indicated numbers on their circumference.

摘要： An improved rpm regulator for a fuel injection pump associated with an internal combustion engine. The regulator includes a control lever, a fuel quantity control sleeve connected to the control lever, a regulating spring assembly connected to the control lever, a device for generating an rpm signal and applying a corresponding force through the control lever to the fuel quantity control sleeve in opposition to a force exerted by the regulating spring assembly and an adjustment lever connected to the regulating spring assembly for adjusting the preload exerted by the regulating spring assembly. The regulating spring assembly is improved and includes two holding members containing two compression springs so that when the two holding members are moved outwardly relative to each other the two springs are compressed. The springs are chosen and the holding members designed so as to minimize the degree of variation which can occur during a control process.
