Abstract
A dispensing device which has a dispensing channel extending between a supply opening and an output opening into the course of which a pump, a selection valve and a dispensing valve are connected. The selection valve is also connected to a pressurised air source. The dispensing device allows a dispensed output of a fluid, wherein a buffer channel portion is filled by the pump in a pump dispensing phase, to which buffer channel portion pressure is applied from the pressurised air source during a pressurised air dispensing phase such that a precise fluid output is subsequently possible by clocked actuation of the dispensing valve until the target fluid amount has been reached.
