Abstract (en)

[origin: US2004074557A1] A microdosage device comprises a media reservoir used for accommodating a liquid to be dosed, a nozzle connected via a connecting channel to the media reservoir and adapted to be filled via said connecting channel with the liquid to be dosed, and a drive unit for applying, when actuated, to a liquid contained in the media reservoir and in the nozzle a force of such a nature that a substantially identical pressure will be exerted on said liquid contained in the media reservoir and in the nozzle. Flow resistances of the connecting channel and of the nozzle are dimensioned such that, in response to an actuation of the drive unit, a volumetric flow in the connecting channel will be small in comparison with a volumetric flow in the nozzle, said volumetric flow in the nozzle causing an ejection of the liquid to be dosed from an ejection opening of the nozzle.
