Abstract

Petite pompe applicable aux récipients pour liquides et actionnable manuellement pour pomper le liquide du récipient, sur lequel elle est montée pour débiter le liquide à travers une buse sous forme finement pulvérisée à pression constante pré-établie. La pompe comprend un corps creux au fond duquel est ménagée une ouverture munie d'une soupape dans laquelle peut se déplacer une tige creuse un petit piston obturateur etant placé à proximité de l'extrémité de la tige intérieure à la cavité du corps creux et un ressort agissant sur le piston et tendant à l'éloigner d'une garniture d'étanchéité solidaire de la tige. A l'extrémité opposée de la tige et du piston est creusé un canal radial permettant la communication avec la cavité de la tige quand celle-ci est maintenue appuyée, et il est prévu une butee pour retenir la garniture avant la butée inférieure du piston.
