摘要： Associated with the fuel controller of a supercharged diesel engine is a mechanism which limits the maximum fuel quantity in all operational states as defined by engine speed and air flow rate. This mechanism includes a three dimensional cam, displaced in rotation by a first transducer responsive to rpm or air flow rate and further displaced axially by a second transducer responsive to the other of these variables. A cam follower attached to the main fuel control rod of the controller makes contact with and follows the surface of the cam, thereby limiting the maximum fuel quantity admitted to the engine. Special provisions permit an enlarged starting fuel quantity and also permit corrections on the basis of further parameters, such as temperature. Several embodiments are presented.

摘要： In the pump work chamber of a fuel injection pump, the main fuel delivered by a first metering valve is admixed with at least one further additional fluid by means of a second metering valve via a second inflow conduit. The two metering valves inserted into the inflow conduits and being electromechanically actuatable receive control pulses (I.sub.Z1, I.sub.Z2) dependent on operating characteristics (n, T, S, L) from an electric control unit. By means of the metering into the pump work chamber, the respective amounts of the fuel components are very well mixed or emulsified and pumped to the injection nozzle. The electric triggering of the metering valves enables a rapid adaptation from one stroke to another of the mixture ratio of the various fuel components to the instant operating condition of the internal combustion engine. A particularly advantageous feature is the use of a refill reservoir receiving the return-flow fuel quantity diverted at the end of supply and returning it to the pump work chamber before the next subsequent supply stroke begins, this refill chamber being connected to an overflow conduit controlled by an oblique control edge on the pump piston.

摘要： In the method according to the invention, the inlet pressure and the inlet cross section of the fuel pre-stored in the pump work chamber is constant, and it is solely the opening duration of an inlet valve which is electrically regulated. In addition, a shift in the instant of supply onset controlled in accordance with operating characteristics is attained by means of a variation in the return-flow fuel quantity. A shift in the instant of supply onset, which is undesired when there is a change in the quantity of fuel to be injected, is prevented by means of a simultaneously-effected correction of the return-flow fuel quantity. A fuel injection apparatus suitable for performing the method has, as the inlet valve, a magnetic valve which determines the quantity of fuel pre-stored in the pump work chamber. The rotary position of the pump piston is variable in order to shift or correct the instant of supply onset by means of an adjacent device actuated by an electromechanical adjustment element. An electric control device emitting the metering pulse and a control pulse is connected with a set-point transducer and an adjustment-path transducer of the adjustment device. The apparatus can be equipped with either a pump/nozzle or a normal piston injection pump supplying the injection nozzle via a pressure line, or with a distributor injection pump.

摘要： In a heating device for atomic absorption spectrometers with electrothermal excitation of a sample, a tubular body for receiving the sample comprises a radial aperture (15) for introducing the sample at the central part of the tubular body. A pair of contacts (1, 2) can be cooled comprise current supplies (3), each consisting of a detachable upper part (5) and a fixed lower part (6) with the upper part and the lower part being connected together so as to be detachable. Each contact comprises an aperture (9) which is coaxial with the tubular body with the apertures extending partly in the upper part and partly in the lower part of the contacts and holding the ends of the tubular body. Damage and deformations of the contacts are avoided in that the diameters of the apertures (9), with the upper parts (5) laid flush on the lower parts (6), are shorter in the vertical direction than in the horizontal direction. The upper parts (5) of the apertures (9) each have a groove (12) which points upwards and extends parallel to the longitudinal axis of the apertures (9). On each end of the tubular bodies (11) a resilient clamping ring (10) is slid whose inside diameter is smaller than the outside diameter of the tubular body (11) and whose outside diameter corresponds to the apertures of the contacts (1, 2). The clamping ring comprises a vertical slot (13) at the area of the lower part (6). Alternatively instead of the clamping rings the ends of the tubular body (11) optionally comprise flanges (14) at its end and are surrounded by graphite foil.
