Zusammenfassung: | The nozzle assembly includes an annular coolant channel that can increase nozzle life, and a readitly changeabel nozzle component; a sleeve is mounted at a predetermined coaxial position w.r.t. the nozzle component. The inner surface of the sleeve and the cylindrical outer shape of the nozzle together delimitate an annular coolant channel; the nozzle component can move forward w.r.t. the sleeve and be changed; a flange on the front end of the nozzle component miantains the nozzle component and prevents it from slip-ping backward from the predetermined position w.r.t. the sleeve; the sleeve has an orifice connected to the annular coolant channel and is used to admit coolant; a kind of sealing element, such as an O ring, is place dbetween the rear part of the nozzle and the sleeve. |
