Device for mixing a fluid and a liquid, especially for introducing carbondioxyde in a water comprising beverage.

摘要

A device for mixing a fluid, for example, carbon dioxide, with a liquid, for example an aqueous beverage solution has a combining part in which one or more infusion chambers are formed within a cylinder by chamber closing plates carried on a common axially shiftable stem. The mixture is passed from chamber to chamber through diaphragm orifices in these plates and the liquid is injected through radial bores in the cylinder wall which can be controlled by collars formed on the edges of the plates. The gas is introduced into the upstream chamber through another radial port. Downstream of the combining part, the mixture flows through an in-line mixer having walls provided with turbulence inducing formations and one of which is movable with the stem.
