Abstract: A dosing device for the pulse-free and continuous supply of very small quantities of medium per unit of time. A cylindrical rotor which can be coupled to a drive has a rotor capable of rotating with a very small amount of play in a cylinder surrounding it; the rotor or cylinder is provided with one or more shallow pumping grooves, each of which is situated in a plane transverse to the rotor axis. Each of said pumping grooves is interrupted in at least one place on the rotor circumference by a dam, the cylindrical outer surface of which coincides with the cylindrical surface of the rotor cylinder. A medium supply duct terminates on the one side of each dam in the relevant groove, and a medium discharge duct communicates with the relevant groove on the other side.

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.
