After this, the reacting substance is reinjected by using the same injection bar (2).

After the injection, the reacting substance (3) is removed from inside the injection bar (2).

The liquid fuel discharge ports (84) are formed by a row of spray nozzles arranged along the downstream edge of the spray bar.

The gas fuel discharge ports (78) are formed into rows on either side of the spray bar.

A material (3) which expands as a consequence of a chemical reaction is injected into the soil (2) through an injection bar (5).

A substance (8) which expands as a consequence of a chemical reaction is injected into the expansion element (5) along the injection bar (4).

After this, the reacting substance is reinjected by using the same injection bar (2).

After the injection, the reacting substance (3) is removed from inside the injection bar (2).

A swivel (74) is coupled to the mounting bar and to the bonnet.

The invention relates to a device for guiding a rod-shaped drive member (401) of an injection device having an exchangeable cartridge with an injection fluid, wherein a guiding element is provided.

The liquid fuel discharge ports (84) are formed by a row of spray nozzles arranged along the downstream edge of the spray bar.

An injection mold (150) for inducing the particular epicycloidal alignement of magnetic domains (D) in the improved bar magnet (130) is provided.

The gas fuel discharge ports (78) are formed into rows on either side of the spray bar.

The device forming the injection channel (2) may be a foam strip (12) applied to the bar (1).

This design of contact strip is particularly suitable for the common electrical connection of electrically operated fuel-injection valves.
