Standard unit with multipart housing body, especially fuel injection nozzle for internal combustion engines

摘要

In injection nozzles with built-in needle movement sensors, the signal lines of the latter are sometimes led through a plurality of housing parts (25, 26), arranged axially in series and braced against one another, thereby making the assembly and also the dismantling of the injection nozzle more difficult. In order to rectify this deficiency, according to the invention plug-in connections (64, 70, 76) are provided on the planes of separation of the housing parts (25, 26), which connections are automatically released when the parts are separated and vice versa. Pump-nozzle standard units are the preferred sphere of application. <IMAGE>
