ABSTRACT:
In a flow mixer for liquid or pasty media, the flow of the mixture is to be interrupted instantly at the end of the usually intermittent discharge of material to prevent continued flow or drooling. To this end, a check valve with predetermined opening pressure is provided, arranged in series with the mixing elements. The valve may be realized in various structural types, e.g. as diaphragm valve and may be arranged either continguous to the mixing elements in the orifice region or preceding the latter in the entrance region of the mixer. The mixer may alternatively contain only one valve part, namely a resiliently movable valve body, which cooperates with the orifice region of a connected double-discharge cartridge.
