Abstract

A metering head for a liquid dispenser with a discharge opening for dispensing liquid from an interior of the metering head into an environment, a metering body and a metering channel within which the metering body is arranged movably between a closed position and an open position. The metering body is designed as a float and is adapted to the metering channel such that, during the movement in the direction of the closed position, liquid flowing to the discharge opening flows around it at least in phases. The metering body is adapted to the discharge opening such that, in its closed position, it closes the discharge opening off from the metering channel. The metering head also includes a ventilation channel separate from the discharge opening and having an inlet valve that opens when there is an underpressure in the metering channel in relation to the environment.
