ABSTRACT:
The present invention relates to a micropump for the nebulization of fluids with enhanced metering valve. The micropump comprises a hollow body and a set of stem and piston such as to constitute a "metering chamber" in the body. The hollow stem, which exits the body, is joined with a dispensing push-button fitted with a nebulization element. Pressing the dispensing push-button allows the passage of the fluid to be nebulized from the "metering chamber" to an exit duct, comprising the longitudinal cavity of the stem, a "compression pre-chamber" in the dispensing button and passages from the chamber to the nebulization element. The metering valve is obtained by interposing, in said fluid exit duct, an elastically deformable shutter.
