Abstract

Inventia se refera la un dispozitiv pentru racirea sapei unei masini de havat, fiind destinat fiecarei sape în parte sau numai acelor sape care sunt solicitate mai puternic permitînd dirijarea apei de racire numai dupa ce sarcina la care este supusa sapa respectiva a depasit o anumita valoare dinainte stabilita. în acest scop, pe axul sapei, care se afla introdus într-un suport fixat pe capul de havare, s-a prevazut un pinten legat rigid cu o tija pe care este fixat un corp de închidere a unui ventil. Pe tija respectiva se afla un resort care este în asa fel alcatuit încît la închiderea apei, acest resort sa actioneze corpul ventilului în sens de închidere, actionînd contrar greutatii partii mobile a ventilului, a sapei si a rezistentelor interne.
