Abstract
Inventia se refera la un cap de havare pentru combine de înaintare în galerii, cap cu cutite si duze amplasate pe periferia acestuia pentru evacuarea apei de racire si pentru stropirea cu apa, în scopul evitarii depunerii prafului rezultat din taierea în roca, duzele fiind alimentate cu apa prin niste canale dispuse axial în interiorul capului de havare al carui corp este constituit din saibe inelare unite una de alta prin sudura. Capul de havare pentru combine de înaintare în galerii, conform prezentei inventii, înlatura dezavantajele de mai sus prin aceea ca are corpul capului de havare realizat prin sudura prin niste saibe în care sunt prelucrate niste inele de distributie, dispuse intercalat cu niste saibe al caror diametru interior este mai mare decît diametrul primelor saibe, astfel ca prin sudarea unor inele al caror diametru interior este comparabil cu diametrul interior al primelor saibe sa se formeze niste spatii inelare libere dispuse aliniat în continuarea canalelor prelucrate în primele saibe, iar o saiba frontala de capat asamblata demontabil la corpul capului de havare etansata fata de urmatoarea saiba în dreptul canalului de distributie prin intermediul unui element de etansare.
