Abstract

Inventia se refera la o instalatie pentru racirea cutitelor în special aflate pe un cap de taiere la combinele miniere, cutitele aflate numai periodic în contact cu roca de taiat precum si pentru umectarea frontului de lucru. Instalatia foloseste drept agent de racire apa, comanda aductiei acesteia efectuîndu-se cu ajutorul unei supape actionate prin miscarea de deplasare a sapei, supapa care este amplasata în suportul cutitului montata pe aceea parte a gîtului cutitului care este orientata spreaxul capului de taiere sau opusa axului capului de taiere.
