Abstract
An apparatus for mixing fluids in accurate predetermined quantities has a feed line for a first fluid (water) under pressure, a suction line for a second fluid (disinfectant) which is to be mixed to the first fluid, and an injector in the form of a fluid jet pump, to which, on the intake side, the feed line is connected. A magnetic valve is positioned in the first fluid feed line. To maintain a precise dosing and to prevent a backflow of the mixture, the feed line is connected to a pressure equalizing container, the fluid level of which is regulated by a fluid pressure switch which controls the magnetic valve. An outlet line from the pressure equalizing container communicates with the inlet of the injector through an air gap.
