摘要： A fuel injection pump for internal combustion engines is described, which for controlling fuel quantity is provided with control unit that controls an electric final control element, which in turn actuates the regulating member that determines the fuel injection quantity per pump piston supply stroke. The supply of fuel to the pump work chamber is effected from a fuel supply chamber, which is kept at a controlled pressure by a fuel feed pump. To limit the maximum speed of the engine supplied by the fuel injection pump in the event of failure of the control unit, a valve is provided in the intake line of the fuel feed pump. Using this valve, the flow cross section of the intake line can be varied or closed. By means of the modification of the fuel pressure in the fuel supply chamber effected thereby, a control of the fuel injection quantity that is not dependent on the position of the quantity-determining member is attained.

摘要： In a pressure control valve for a fuel injection pump, which includes a piston displaceable in the cylinder by the pressure fluid admitted in the cylinder and against the force of a restoring spring which biases the piston, the piston is closely guided in the cylinder with an annular gap which can be maintained constant. The piston includes one portion which forms the annular gap with the wall of the cylinder and two lateral guide portions closely guided in the cylinder. The annular gap is in communication with the pressure control chamber and the spring chamber formed in the cylinder. A throttle is formed at the discharge of the spring chamber. The amount of fuel flowing through the annular gap builds up a compensation pressure at the throttle to compensate for the influence of temperature fluctuations in the fluid admitted in the pressure control chamber of the cylinder.

摘要： An apparatus for the load-dependent actuation of an adjusting device of an internal combustion engine, in particular of a throttle valve, of an exhaust gas recirculation line leading to the intake tube of the engine, in which the adjusting device is controlled in accordance with the position of a governor sleeve of a governor of an injection pump filled with fuel. The fuel in the injection pump, which is at an interior pressure (p.sub.1), is utilized as a hydraulic operating medium, and the position of the governor sleeve is ascertained via a self-balancing hydraulic follower piston apparatus. In order to preclude influence on the part of the interior pressure (p.sub.1), which is dependent on the pump rpm, the follower piston apparatus is disposed such that in the balanced status it is exposed on both ends to a pressure corresponding to the interior pressure (p.sub.1).

摘要： A magnetic tape recorder for recording as well as for playback of sound, having a noise suppression device, and sensor member with an abutment surface for engaging against an unopened break through tab of a tape cassette for causing a locking mode for the recording device to be inoperative. The sensor member has an additional abutment surface arranged such that the latter abutment surface senses the wall of the cassette outside of the broken-through penetration opening of the cassette and the insert movement of the sensor member is limited in the opened penetration opening. The sensor member is connected with the locking device; such that in the absence of the limitation due to the absence of a cassette, the locking device, is also inoperative.

摘要： An improved rpm regulator for a fuel injection pump associated with an internal combustion engine. The regulator includes a suction chamber, an intermediate lever, a fuel quantity control sleeve connected to the intermediate lever, a regulating spring assembly connected to the intermediate lever, a device including centrifugal weights and a governor sleeve for developing and transmitting an rpm signal through the intermediate lever to the fuel quantity control sleeve in opposition to a force exerted by the regulating spring assembly, a control lever, and an adjustable stop, including a cam member, mounted to the housing for limiting the motion of the intermediate lever. A working chamber is provided between the governor sleeve and an end of a guide shaft forming part of the device for transmitting an rpm signal. Openings are provided in the governor sleeve which communicate with the suction chamber for effecting a damping of oscillations of the governor sleeve during predetermined load conditions.

摘要： 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).

摘要： A fuel injection apparatus for internal combustion engines comprising a pump work chamber defined in a bore of a housing by a pump piston. The pump work chamber is supplied with fuel and relieved via a fuel line containing a magnet control valve. Moreover, the pump work chamber communicates with an injection valve via a supply line. Controlling of the injection is done via the opening or closing of the magnet control valve during the pumping stroke of the pump piston; to that end, the magnet valve is triggered by a control unit. To enable performing an accurate injection, a needle stroke transducer is disposed on the nozzle needle of the injection valve; if a limit value is exceeded, its stroke motion is detected as a precise signal for the onset and end and hence the size of the injection quantity and is transmitted to the control unit, where this actual value is compared with a set-point value from a performance graph, and a correction of the magnet valve triggering is consequently done performed, if needed.

摘要： 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.
