Abstract
Un dispositivo dosatore comprendente: un tubo di adduzione per la sostanza da dosare, chiuso alla sua estremità di erogazione e presentante presso tale estremità due aperture laterali di erogazione, una di grande sezione e l'altra, più vicina all'estremità di erogazione, di piccola sezione; un manicotto montato sul tubo di adduzione, scorrevole sostanzialmente a tenuta su di esso e terminante, verso l'estremità di erogazione del tubo, con un bordo affilato; un mezzo soffiante, montato sul manicotto e formante un ugello in corrispondenza delle aperture di erogazione del tubo di adduzione, questo mezzo soffiante presentando nel suo interno una camera, comunicante con l'ugello e connessa ad una sorgente di aria compressa; e mezzi per spostare il manicotto lungo il tubo di adduzione fra una posizione di erogazione, in cui il manicotto lascia scoperte entrambe le aperture di erogazione del tubo di adduzione, ed una posizione di intercettazione, nella quale il manicotto occlude entrambe le aperture di erogazione del tubo di adduzione, attraverso una posizione intermedia nella quale il manicotto copre l'apertura di erogazione di grande sezione ma lascia scoperte l'apertura di erogazione di piccola sezione.
