ABSTRACT:
An arrangement limits a fuel supply from a fuel pressure reservoir by way of a controllable injection valve into the combustion space of an internal-combustion engine. The fuel flow is interrupted as a function of the forces applied to a spring-prestressed valve separating piston in the event of an outlet-side pressure drop. A reliable limiting of the maximal injected fuel quantity is achieved by providing a flow-through opening penetrating the separating piston with a closing device. This flow-through opening can be closed as a function of the displacing direction of the separating piston. If the displacing device closes the flow-through opening in the starting position, during the injection phase and in the piston end position, the limiting valve will continuously interrupt the fuel flow in the case of an outlet-side pressure drop. Alternatively, the flow-through opening is such that a fuel filter cartridge can be inserted into the separating piston, through which fuel, which was apportioned between two respective injection phases, flows during the restoring stroke.
