Abstract

Inventia se refera la un dispozitiv pentru racirea sapei unei masini de havat, fiind alcatuit dintr-un ventil actionat de deplasarea axului sapei permitînd dirijarea apei de racire spre frontul de lucru numai în raport de duritatea rocei în care lucreaza sapa respectiva. Dispozitivul este actionat de corpul sapei care este în legatura, prin intermediul unui pinten, cu tija unui ventil, tija pe care este fixat un corp conic de închidere care în momentul cînd este asezat pe scaunul unui corp cilindric al unui ventil, datorita presiunii create de un resort si de apa de racire, închide calea de trecere a apei de racire spre duza de evacuare. Deschiderea ventilului se face numai cînd presiunea de taiere depaseste rezistenta la comprimare a cuburilor din roca de havat de cel putin 20N/mm2.
