ABSTRACT:
A fuel injection installation for internal combustion engines having a plurality of injection valves for supplying fuel to the engine. Each injection valve is sealed to fuel distributing line and to either the intake manifold of the engine, or to the cylinder head of the engine, by at least one O-ring, each O-ring being braced only in the radial direction. Each injection valve is fixed in an axial direction on the fuel distributing line by means of a fastening plate yielding in the radial direction and embodied as bracket-like, which is insertable through appropriately shaped recesses in each insertion nipple on the fuel distributing line and can be snapped into an annular groove of each injection valve. As a result, there is assured not only a secure connection between the fuel distributing line and the injection valves which compensates for axial clearances required for manufacture, but also rapid mounting or dismounting of the fuel injection installation.
