Fluid e.g. fuel, injector`s metallic body for internal combustion engine of motor vehicle, has electrical conductors led through ceramic bodies that are fastened to recesses by hard solder joints, and grooves formed outside recesses

摘要

The body has recesses (14, 14 `) through which electrical conductors (12, 12 `) are guided. The conductors are led through ceramic bodies (16, 16`), which are fastened to the recesses by hard solder joints (18, 18`). Each solder joint consists of a solder comprising silver, titanium and copper, and the fusion temperature of the solder ranges between 700 and 1000 degree Celsius. The conductors are fastened to the ceramic bodies by another set of hard solder joints in a leak-proof manner. Circular grooves are formed radially outside the recesses.
