Abstract
A device, cartridge and method for dispensing a liquid, preferably a drug, are proposed. The liquid is pressurized in a cartridge to a first lower pressure and, then, pressurized in doses by a pump to a second higher pressure. A valve arranged between the cartridge and the pump is normally closed and/or opened only temporarily. Thus, evaporation and dripping of liquid can be avoided or minimized.
