ABSTRACT:
A device is used for spraying and atomizing a liquid which is held in a container which can be emptied by air pressure. If in a device of this kind a liquid nozzle projects into a mixture nozzle disposed coaxially in front of it, so that an annular space provided for air around the liquid nozzle is open at the front towards the mixture nozzle, the feed paths for liquid and for air must not be transposed. Such transposition occurs if the container is held upside-down during spraying. In order to avoid this disadvantage two annular spaces are provided, from which passages lead to a mixture nozzle. The two annular spaces communicate with one another via throttle slots. Because of the two annular spaces the liquid can also be sprayed when the container is upsidedown.
