Arrangement with an injection valve and a sleeve as pressure transfer means

An arrangement with an injection valve ( 7 ) is disclosed, arranged in a cylinder head ( 1 ) and which permits the recording of the pressure in the combustion chamber ( 21 ) of an internal combustion engine ( 22 ). A pressure sensor ( 16 ) is thus provided, mounted on the injection valve ( 7 ). A sl...

Zusammenfassung:An arrangement with an injection valve ( 7 ) is disclosed, arranged in a cylinder head ( 1 ) and which permits the recording of the pressure in the combustion chamber ( 21 ) of an internal combustion engine ( 22 ). A pressure sensor ( 16 ) is thus provided, mounted on the injection valve ( 7 ). A sleeve ( 13 ) is provided as pressure transfer means, enclosing a nozzle body ( 8 ) of the injection valve ( 7 ), the upper end of which rests on the pressure sensor ( 16 ). The lower end of the sleeve ( 13 ) runs in a drilling ( 2 ) in the cylinder head ( 22 ) as far as the region of the end of the drilling ( 2 ). A pressure change in the combustion chamber ( 21 ) is transmitted to the sleeve ( 13 ) by the lower end ( 14 ) of the sleeve ( 13 ), in the form of a annular surface and transmitted to the pressure sensor ( 16 ), by means of the sleeve ( 13 ). The embodiment of the sleeve ( 13 ) permits an economical and simply produced pressure transfer means.
