Definition and range of application
Definition
The nozzle is described in Brockhaus' "ABC's of Science and Technology" as the mouthpiece of the pipe which is used to narrow the flow channel, thus transforming pressure into velocity (pressure nozzle) or velocity into pressure (suction nozzle).
Consecutively, the following definition is used:
The flushing nozzle head is understood to include either fixed jetting inserts, or threaded bores into which the corresponding jetting inserts can be screwed.
