Abstract (en)

[origin: EP0219800A2] The device has an inflow line for a first, pressurised liquid as well as at least one suction line for a second liquid, to be mixed in with the first liquid, and an injector in the form of a liquid-jet pump, to the inlet side of which the inflow line is connected, in which a solenoid valve is arranged, and to the suction side of which the suction line is connected, which can be connected to a supply tank for the second liquid. To maintain accurate metering and to prevent a flow back of the mixture, the inflow line is connected to a pressure equalising tank, the liquid level of which is regulated by a liquid pressure switch, controlling the solenoid valve, and the outlet line of which is arranged to flow into the inlet of the injector, with an air gap left inbetween. <IMAGE>
