Device for parallel dosing of liquids

摘要

The apparatus for a parallel fluid dosing has a body (20a) with a main channel (8), side channels (9-12) branching from it, an inflow (1) into the main channel and an outflow (6) at each side channel. A chamber is filled with a pressure medium, with units to transfer pressure pulses from the chamber into each of the side channels. A piezo electric component triggers the pressure pulses. The apparatus for a parallel fluid dosing has a body (20a) with a main channel (8), side channels (9-12) branching from it, an inflow (1) into the main channel and an outflow (6) at each side channel. A chamber is filled with a pressure medium, with units to transfer pressure pulses from the chamber into each of the side channels. At least one membrane (21) blocks any flow link between the side channels and the pressure chamber. The end of the main channel has a link (13) to the waste collection chamber (7). A piezo electric component triggers the pressure pulses.
