A supplier (1) is presented that contains a box (2) with a feeding chamber (11) of variable volume for a certain medium or substance with a discharge closure (10) which closure member (50) directly remains next to the nozzle outlet (8) and which control device (18) works depending on the pressure totally found within the box (2). The control device (18) is placed in a carrier unity (5) separated from the box (2), unit which limits channels (28, 29, 38, 47) for two different mediums. Thus, with a simple construction and an easy assembly the contamination of the stored medium can be avoided.
