Metering units for viscous substances, e.g. adhesive or solder paste comprise a cartridge (K) filled with said viscous substance and to which compressed air can be applied via a compressed air supply (DA) and at least one metering nozzle (DD) or needle.

Therefore, no carburetor or other vaporizing device is required; a simple metering nozzle suffices.

Said atomising nozzle comprises a nozzle body (2) provided with spray openings (3) which end in a dosing chamber, and at least one dosing opening (6).

A metering device is associated with each dispensing nozzle.

An atomising nozzle (1) for fuels, in particular for introduction into a chemical reformer for the production of hydrogen, comprises a nozzle body (2) with discharge openings (3) which discharge into a dosing chamber and at least one dosing opening (6).

According to the invention, at least one dosing pump is associated with each nozzle holder by means of a fluid connection.

A nozzle is provided for the outflow of material from the reservoir to a metering cup.

The invention relates to an injection nozzle (1), especially for a dosing system for dosing urea or the like.

Each nozzle has a nozzle inlet, a nozzle outlet, and a nozzle passageway extending between the nozzle inlet and the nozzle outlet.

A control signal (ANS_SIG) for metering fluid with the injection valve is generated for a first valve pin actuator which is coupled to the valve pin to drive the valve pin.

The invention relates to a nozzle element (2) for dosing liquids or gases.

Said metering device (1) comprises at least one dosing feeder (2) for apportioning fuel into a dosing conduit (8) and a nozzle member (7) which adjoins the dosing conduit (8) and is provided with spraying ports that extend into an apportioning space.

The invention is a liquid fertiliser dispensing nozzle that contains a flow control device to adjust the rate of flow of a pressurised liquid fertiliser and a mering deice for such a nozzle.

Said nozzle element comprises a nozzle body (4) and a nozzle needle (6) which is mounted in a guide bore (5) of the nozzle body (4) and can be displaced between an open and a closed position.
