Abstract (en)
[origin: EP0544549A1] The pump (1) comprises a pump body (4) intended to be mounted on a container (2) containing the product (P) to be dispensed and a push button (12) suitable to be pushed in against elastic return means (31) in order to dispense the product, the said pump including a precompression valve suitable for allowing the product to be dispensed only when a sufficient pressure is reached, air-compressing means being furthermore provided in order to blow air through the nozzle (13) after dispensing the product. The air-compressing means (12, 24) are arranged so as to blow air, through the nozzle (13), during the phase when the push button (12) rises up under the action of the elastic return means (31); during the phase when the push button (12) is lowered, the aforementioned air-compressing means (24) suck air in with a view to subsequently expelling it, while a metered amount of product (P) is dispensed through the nozzle (13). <IMAGE>
