Abstract

The invention relates to a fuel injection apparatus for an internal combustion engine, having an injection valve that protrudes into the combustion chamber of the engine. This valve communicates with a valve chamber in that a control part closes and opens inlet bores for fuel that is at high pressure. The control part is actuatable by means of a hydraulic-mechanical booster. The pump part, valve part and nozzle part of the fuel injection apparatus are disposed in a vertical arrangement, hydraulically in line with on another in terms of the fuel flow.
