Abstract

Nella testa in oggetto è prevista, realizzata al suo interno ed in corrispondenza del fondo della sede (6) di alloggiamento di una turbina, una sede toroidale (8) collegantesi, in corrispondenza del proprio fondo, con un condotto di alimentazione (4); entro questa sede toroidale (8) è alloggiato un primo anello (9) presentante una cavità (10) di collegamento con un altro condotto di alimentazione (5) mediante un foro laterale (11) e presentante la propria porzione non interessata dalla cavità (10) con una configurazione tale da sposare parzialmente la sede toroidale (8) così da definire, inferiormente, un meato (12) di passaggio per il fluido proveniente dal primo dei condotti di alimentazione (4); il primo anello (9) è previsto di una serie di fori (13) passanti di collegamento della cavità (10) con il meato (12) e con una corrispondente serie di secondi condotti (7a) inclinati di uscita, realizzati sulla porzione inferiore della testa (2), così da permettere l'uscita di un flusso di detta aria ed acqua convergente nell'intorno dell'estremità operativa di un utensile (3); un secondo anello (15) è previsto inseribile sull'estremità aperta della sede toroidale (8) atto a permettere la chiusura a tenuta della stessa sede (8) e della cavità (10) del primo anello (9).
