Abstract
The invention relates to a discharge device for discharging liquid medium, with a pump device with a variable volume pump chamber, a discharge opening for the liquid medium, a feed path between the pump device and the discharge opening, and an outlet valve which is designed to open the discharge opening as a function of the pressure in the feed path, and to a discharge head provided for this purpose. The discharge device or the discharge head has a gas-permeable and liquid-tight air outlet which connects the pump chamber or the feed path to an external environment.
