Abstract
Inventia se refera la un dispozitiv pentru racirea cutitului unei haveze miniere. Dispozitivul prevede ca în suportul cutitului sa fie introdus un cap de lucru, care este fixat prin însurubare. Etansarea dintre suportul cutitului si capul de lucru este realizata cu ajutorul unei garnituri, care este amplasata la baza filetului din capul de lucru, unde acest cap îsi mareste diametrul printr-o parte conica. Pe capul de lucru este montat un cutit rotativ, de forma unei calote cilindrice, care la partea de sus se continua cu o parte tronconica. Aproximativ la mijlocul calotei cilindrice este prevazut un canal circular, iar în dreptul acestuia, în capul de lucru, se afla un alt canal circular, iar în dreptul acestuia, în capul de lucru, se afla un alt canal circular. Unul din canale este executat în partea interioara a cutitului rotativ, iar celalalt canal circular este executat în partea exterioara a capului de lucru, astfel încît cele doua canale circulare, fiind fata în fata, formeaza un spatiu toroidal, în care este amplasat un inel de protectie. lungimea în directie longitudinala a canalului circulat din capul de lucru este ceva mai mare decît inelul de protectie sus mentionat. în acest mod cutitul rotativ este montat deplasabil axial pe capul de lucru. în el exista o gaura centrala, unde este amplasata o tija cilindrica deplasabila axial, care este profilata înspre partea ei mijlocie. Aceasta este prevazuta cu o parte conica de supapa, un resort elicoidal, amplasat sub partea conica de supapa ce împinge în sus tija cilindrica, astfel încît partea conica de supapa se aplica pe un scaun vertical, executat într-o camasa cilindrica. în mod c
