摘要： A clamping device in the form of a bracket for use in clamping a fuel injection nozzle to the cylinder head of an internal combustion engine. The clamping device has a generally flat top portion and a pair of legs extending therefrom which together define a U-shaped cross-sectional profile. The top portion includes a slot for receiving a portion of the injection nozzle while the free ends of the legs bear against flat portions of the injection nozzle.

摘要： A fuel injection system for internal combustion engines with a pressure step-up means is proposed, in which the fuel is pumped out of the low-pressure supplier into the injection nozzle via a feed line and is measured correctly in terms of time and quantity via a control line by the high-pressure part of the injection pump.

摘要： A fuel injection nozzle for internal combustion engines for preinjection and main injection has an inwardly opening valve needle which is loaded by a single closing spring. After a prestroke (h.sub.v), in which the supply pressure in combination with the effective surface area of the valve needle controls the stroke, a stroke switchover to an interposed piston takes place, the effective surface area of the piston is less than that of the valve needle. Because the force of the piston that tenses the closing spring is reduced proportionally compared with the force of the valve needle, a flatter opening of the valve needle takes place after the prestroke (h.sub.v) than during the prestroke.

摘要： An insulating layer is grown on a principal face of a substrate that comprises a source terminal region. A first opening wherein the surface of the source terminal region is partially uncovered is provided in the insulating layer. A vertical layer sequence that comprises at least a channel region and a drain region for the MOS transistor is produced in the first opening by epitaxial growth of semiconductor material within situ doping. A second opening that is at least of a depth corresponding to the sum of the thicknesses of drain region and channel region is produced in the layer structure, a gate dielectric is applied on the surface thereof and a gate-electrode is applied on said gate dielectric.

摘要： A fuel injection nozzle for internal combustion engines having a filter body inserted into the fuel inflow conduit, an injection valve and a check valve, which maintains a static pressure in the injection nozzle and can also perform a relief function for the prevention of after-injections. The check valve is integrated into the filter body thereby simplifying the final assembly of the injection nozzle. The filter body is advantageously embodied as a rod-type filter, which by the appropriate shaping of its jacket periphery forms gap-like spaces between itself and the surrounding wall of the nozzle holder through which spaces the fuel must pass such that it is deflected multiple times.

摘要： A fuel injection nozzle for internal combustion engines, having a valve needle arranged to open toward the outside and said valve needle further connected with a piston which defines a fuel-filled damping chamber, which communicates with the flow path of the fuel only via a throttle conduit during the opening stroke of the valve needle. The damping chamber is formed in a cap which is placed onto the piston. As a result, jamming of the elements in the radial direction is avoided. Furthermore, the piston may be embodied by the valve needle per se, resulting in a simple and space-saving construction. By means of the appropriate embodiment and supporting of the cap, the damping effect can be limited dependent on the stroke and/or the travel speed of the valve needle.
