Abstract

La présente invention a trait à un distributeur de liquide (1) dosé à propulsion mécanique, comportant un corps principal cylindrique (3) comprenant du liquide (41) et un mécanisme d'avancement de liquide (43 et 47) permettant de faire avancer le liquide (41) dans une chambre de distribution de mesure de dosage (11). Il est prévu un mécanisme d'armement (23) comportant un dispositif de blocage (21), une fente d'actionnement (25) et une fente de repos (33). Lorsque le mécanisme d'armement (23) est verrouillé, le moyen d'avancement (43 et 47) se déplace et le liquide (41) est prêt à être propulsé à partir de la chambre de distribution de mesure de dosage (11) à travers un orifice de distribution. Le mécanisme d'armement (23) est entraîné lentement en rotation tout en maintenant le cylindre du corps principal (3) à la verticale et le dispositif de blocage (21) est déplacé manuellement dans la fente de repos (33) entraînant ainsi un plongeur (19) à être soumis à une force de poussée par un ressort (17) contre une butée (15) sur la détente (13) qui fait avancer la détente (13) pour forcer rapidement le liquide (41) hors de la chambre de distribution de mesure de dosage (11) à travers l'orifice de distribution. L'orifice de distribution comporte un clapet de non-retour (37).
