Abstract: A dosing device for the pulse-free and continuous supply of a very accurate small flow of liquid comprising a rotor which is enveloped by a housing and is coupled to a motor. The rotor has shallow liquid pumping grooves and is vertically arranged. One side of the housing is closed by a wall having an outlet aperture and the other side communicates with an auxiliary container. The container has a cover plate carrying two tubes extending into the container. One tube extends deeper down in said container than the other, and is cut off at an angle, and is wider than the first tube. Both tubes are capable of communication with a closed container having the liquid to be dosed.
