  • Patent number: 6523723
    Abstract: Dosing feeder for a liquid that is in a container (6), comprising a dosing arm (2) that shows at least one dosing cup (2.1) that is open at the top. The dosing arm (2) is arranged in a dosing head (3) that in its turn shows a first duct (4.1) being in connection with the container (6). The dosing head (3) is movable or turnable in relation to the dosing arm (2) so that the dosing cup (2.1) alternately may be brought in connection with the first duct (4.1) for feed of liquid or may release the dosing cup (2.1) so that it gets accessible for the liquid. The dosing arm (2) may be cylinder-shaped, the dosing head (3) being turnable around the dosing arm (2). On filling with liquid into the dosing cup (2.1) the container (6) is above the dosing arm (2), the first duct (4.1) being connected with the dosing cup (2.1.). In position of rest the container (6) is under the dosing arm (2), the second duct (3.2) being connected with the dosing cup (2.1).
