device for suction of additives in a flüssigkeitsströmung

摘要

The invention relates to a device for the aspiration and addition of additives in a fluid flow by means of a T-shaped connection piece having a through-channel for the fluid and a connecting channel, opening perpendicularly thereto, for the additive. To generate a sufficiently high vacuum, a stopper projects transversely into the fluid flow, so that the fluid flow is largely blocked and only narrow flow gaps to the side of the stopper remain free. As a result, such a high vacuum is generated on the side of the stopper remote from the flow that even gel-like substances such as bath additives and the like can be sucked off there. IMAGE
