Title:
INJECTION VALVE FOR INTERNAL COMBUSTION ENGINES
Document Type and Number:
WIPO Patent Application WO/2005/108773
Kind Code:
A1
Abstract:
The invention relates to an injection valve comprising at least one first body (20) and a second body (22) that are pressed together in the axial direction. The first body (20) and the second body (22) are respectively provided with at least one borehole (21, 23) and/or recess (24, 25) in which, for example, fuel can be guided, or an injection needle or another component of the injection valve can be arranged. The aim of the invention is to ensure a reliable operation of the injection valve and the required high-pressure resistance. To this end, the respectively corresponding boreholes (21, 23) and/or recesses (24, 25) are oriented and centred in the bodies in relation to each other. Furthermore, a centring device (19) is inserted into the boreholes (21, 23) and/or recesses (24, 25) in the bodies, said device exerting a leadthrough function in addition to a centring function.
