Abstract: A device and technique for proportioning of beverages while they flow which employ the working of gravity on a cyclic basis. The technique is based on a driving wheel's rotation initiated by an outflow of liquid. For the duration of a single cycle of proportioning, a set amount of beverage is allowed to flow out, which is in a direct ratio to the continuance of a proportioning cycle as completed by the driving wheel and in a reverse ratio to the rate of rotation. The rate of rotation is being set by the degree of inclination of the driving wheel's blades. The higher the blades' degree of inclination, the higher the driving wheel's rate of rotation is; this results in a smaller amount of liquid allowed to flow out (i.e. be proportioned) for the duration of a single cycle, and vice versa.
