摘要

1. Device for the dosewise tranfer of liquid from a first chamber (PK), arranged on a rotor (R) with vertical axis of rotation (X-X) to be set in rotation with variable speed of rotation, formed in a block with a filling opening (5) into a second chamber (·UK) formed in block on the rotor (R) radially outside the first chamber (PK), whereby the volume of the first chamber (PK) is substantially greater than the volume of the second chamber (·UK), characterized in that the first chamber (PK) is connected on its side facing the second chamber (·UK) via a capillary throttle (16) with a dosage chamber (DK), extending substantially downwardly, formed in the block between the first chamber (PK) and the second chamber (·UK) and that the dosage chamber (DK) is connected below with the inlet (10) of a capillary tube (Kap ; RS, K) formed in the block extending radially inwardly up to under the first chamber (PK) and then radially outwardly, which has an outlet (12) leading to the second chamber (·UK), radially outwardly further removed from the axis rotation (X-X) than its inlet (10).
