Abstract

Il tipo di polverizzatori sul quale si applicano i perfezionamenti dell'invenzione comporta un serbatoio (1) che è trasportato sulle spalle dell'utilizzatore, in questo serbatoio, e in prossimità di uno dei lati (4), è alloggiata internamente una camera a stelo la cui estremità inferiore è parzialmente alloggiata in un cilindro (7) previsto sul fondo del serbatoio (1), questo cilindro dispone di una leva manuale (5) che è articolata ad una biella (6). Uno dei perfezionamenti consiste nel fatto che i tubi (9 e 10) che formano la camera a stelo sono uniti tra loro tangenzialmente, l'uno all'interno dell'altro, mentre il tubo piccolo (13) attraverso il quale esce il liquido, è solidale a questa camera a stelo e fatto dello stesso materiale. Un altro perfezionamento consiste nel fatto che la parte superiore della biella (6) sulla quale è articolata la leva (5) è solidale alla camera a stelo menzionata. Un altro perfezionamento consiste nel fatto che la chiusura ermetica tra la camera a stelo e l'imboccatura (3) nella quale essa è alloggiata è ottenuta mediante una coppia di anelli (15 e 16) di elastomero uniti tra loro mediante una sottile parete (17).The type of sprayer on which the improvements of the invention are applied involves a tank (1) which is transported on the shoulders of the user, in this tank, and near one of the sides (4), a stem chamber is housed inside whose lower end is partially housed in a cylinder (7) provided on the bottom of the tank (1), this cylinder has a manual lever (5) which is articulated to a connecting rod (6). One of the improvements consists in the fact that the tubes (9 and 10) which form the stem chamber are tangentially joined together, one inside the other, while the small tube (13) through which the liquid comes out, it is integral with this stem chamber and made of the same material. Another improvement consists in the fact that the upper part of the connecting rod (6) on which the lever (5) is articulated is integral with the stem chamber mentioned. Another improvement consists in the fact that the hermetic closure between the stem chamber and the mouth (3) in which it is housed is obtained by means of a pair of elastomer rings (15 and 16) joined together by a thin wall (17 ).
