ABSTRACT:
An apparatus for admitting metered quantities of a flowable additive into a liquid stream has a horizontal metering cylinder which is surrounded by a connector supporting a vessel for a supply of additive. The additive is free to flow into the cylinder when the connector is turned about the cylinder to move the vessel to a higher level, and the vessel is sealed from the interior of the cylinder when the connector is turned to a different position in order to lower the vessel. A manually operated or fluid operated piston is provided in the cylinder to expel a metered quantity of additive into a conduit which supplies a stream of tap water or another cleaning liquid to a shuttle valve forming part of an apparatus for cleaning pipelines in breweries, bars and similar establishments.
