Abstract: This invention relates to a device for dosing and mixing of two or more liquids. According to the invention, the liquids are led to a chamber (26) where they are mixed, an outlet (30) from the chamber being closed at the same time. When the chamber (26) has been filled, the outlet (30) is opened while the inlets (21, 22) for the starting liquids are simultaneously closed, and when the chamber (26) has been emptied, the outlet (30) is closed again and the inlet or inlets (21, 22) are opened. This cyclic process is repeated any desired number of times. The chamber has a variable volume, and changes of the volume are sensed by a sensor (28), which controls the opening and closing of the inlets and the outlets.The device for carrying out the method is provided with a mechanical bistable flip-flop device, which in one of its stable positions opens the inlets (21, 22) and closes the outlet (30), and in the other stable position closes the inlets and opens the outlet.
