Fuel-injection valve for internal combustion engines

摘要

An injection valve member for closing or opening injection orifices of a valve seat element is integrated, in a longitudinally displaceable manner, into a central housing bore of a fuel-injection valve. The valve seat element is fixed to the housing and the part of the element that includes the injection orifices and the seat projects out of the housing. Elements for determining the rotational position of the valve seat element in relation to the housing are provided on the exterior of the part. The fuel injection valve requires simple production and assembly engineering and permits a slimline injector configuration for both large and small internal combustion engines.
