摘要： Valve unit for metering a liquid, comprising a chamber into which a liquid supply pipe opens and which has a passage formed in the bottom thereof, and a shut-off element which is fitted at a bottom end of a lifting rod of a lifting mechanism and is vertically displaceable by the lifting mechanism between a closed position in the passage in which it shuts off the passage and an open position in which it opens the passage for allowing the liquid to pass out of the chamber, while a space bounded by a wall of the passage and the shut-off element gradually increases during the lifting of the shut-off element from the closed position to the open position, wherein the shut-off element is essentially cylindrical, and the shut-off element is essentially a truncated inverted cone shape, while in the closed position a bottom end of the shut-off element projects in a sealing manner past a bottom boundary edge of the passage.
