Micro dosing device for a liquid medium

A manually-operated pump (3) is associated with the flow channels (5, 6, 7), to supply fluid into the dosing chamber (D) and/or to return fluid from the dosing chamber into the storage vessel (2). A sensor (4) detects filling by the pump, and signals the controller (S), which correspondingly, switch...

Zusammenfassung:	A manually-operated pump (3) is associated with the flow channels (5, 6, 7), to supply fluid into the dosing chamber (D) and/or to return fluid from the dosing chamber into the storage vessel (2). A sensor (4) detects filling by the pump, and signals the controller (S), which correspondingly, switches vibration on or off. A mechanical piston pump is used. Each flow channel has a valve arrangement (8, 10, 11). These valves are mechanical non-return valves, opening or closing in accordance with the pressure across them. A filter (12) is included in the flow channel (6).
