Abstract
The present invention relates to an enhanced micropump for the nebulization of fluids. The micropump, mounted on a bottle cap, comprises a hollow body and a set of stem and piston such as to constitute a 'metering chamber' in the body. The set, protruding outside 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 nebulizer from the 'metering chamber' to an exit duct for the fluid itself, comprising a 'compression pre-chamber' in the dispensing button and passages from the chamber to the nebulization element. A metering valve is obtained by interposing, in said fluid exit duct, an elastically deformable shutter positioned in a cylindrical seat in the top end of the set.
