Abstract
A discharge apparatus for media has a medium pump and a compressed air pump, as well as control means through which, in stroke-dependent manner, precompression only takes place in the air pump during a first partial stroke and then during a further partial stroke delivery takes place from both pumps following a pressure-dependent opening of the delivery valve and finally during a further partial stroke delivery only takes place from the air pump. In order that the medium pump does not deliver to the outlet channel over intermediate and final partial strokes, delivery takes place back into the reservoir via the inlet channel.
