Abstract

L'invention se rapporte au domaine de l'agriculture. Cette pompe-pulvérisateur comprend un cylindre à une extrémité duquel est monté un clapet anti-retour en forme de bille avec un raccord d'aspiration, tandis qu'à l'autre extrémité se trouve une tige de pulvérisation creuse qui est montée dans un piston à degrés avec un clapet de pompage. Le clapet de pompage se présente sous forme d'une bille et est disposé dans une cavité axiale traversante du piston avec un limiteur de déplacement dans la zone du piston. Le limiteur de déplacement de la bille est formé par un siège de l'ouverture de sortie du piston et par des renflements sur les parois. La bille du clapet anti-retour est disposée et limitée en déplacement entre le siège de l'ouverture de sortie du cylindre et l'extrémité du piston. Au-dessus du cylindre se trouve un récipient de contenance dont l'ouverture de sortie coïncide avec l'ouverture d'entrée du cylindre. Le raccord pour fixer le tuyau d'alimentation en liquide à la pompe est disposé sur le côté dans la partie inférieure du réservoir de contenance. La cavité de la tige possède un même diamètre sur toute la longueur jusqu'au réservoir de contenance. Il est ainsi possible d'exclure toute nécessité de pompage constant du liquide vers la buse, et de réduire la fatigue de l'utilisateur lors du travail avec la pompe.
