Title (EN) HAND-OPERATED APPLICATOR FOR MEDIA
(FR) DISTRIBUTEUR MANUEL DE MILIEUX
Abstract:
(EN) In a hand-operated applicator (1), the medium pump (2) which conveys the medium has an extender in the form of a compressed air pump (50) located in a cap-shaped common handle (22) connected coaxially and directly to the outer end of the medium pump (2). The compressed air pump (50) forces compressed air through a compressed air channel (90), which is separate from the medium conveying system and produces finer spray, into the application nozzle (25) or into other areas of the applicator, for example into the medium discharge channel (24), so that this channel can also be cleaned by purging. The compressed air pump (50) can be designed so that it begins conveying compressed air before the medium pump (2) starts conveying the medium and stops conveying compressed air after the medium pump (2) stops conveying the medium. In addition, an at least two-stage atomizer (100) for additional atomization of a previously atomized medium flow with an air flow from the nozzle is advantageously provided in the region of the applicator nozzle (25).
(FR) Un distributeur manuel (1) comprend une pompe à air comprimé (50) qui prolonge la pompe (2) de transport du milieu, immédiatement adjacente à l'extrémité extérieure de celle-ci, dans la même direction axiale, à l'intérieur d'une poignée commune (22) en forme de capuchon. La pompe à air comprimé (50) permet d'introduire de l'air comprimé dans le bec distributeur (25) par un canal à air comprimé (90) séparé du canal de transport du milieu, afin d'obtenir une vaporisation plus fine, ou dans d'autres parties du distributeur (1), par exemple le canal (24) d'évacuation du milieu, ce qui permet de nettoyer ce canal en y insufflant de l'air comprimé. La pompe à air comprimé (50) peut commencer à fournir de l'air comprimé avant que la pompe (2) ne commence à pomper le milieu et finir de fournir de l'air comprimé après que cette dernière ait fini de fonctionner. Un dispositif atomiseur additionnel (100) à au moins deux étages est agencé de façon appropriée dans la région du bec distributeur (25) afin d'effectuer une vaporisation plus poussée d'un courant de milieu vaporisé au préalable, au moyen d'un courant d'air produit par le bec.
