Spray nozzle head of main and mixing tubes and combining nozzle

摘要

The mixing tube (8) can adjust coaxially relative the nozzle jet (12) and the inserted tube can be replaced by a tube of modified inside diameter. The nozzle (12) has a spiral outside groove (13) and the tube has an outside thread (10) to screw coaxial to the nozzle jet into the inside thread (11) of the intermediate tube (4). A diffuser on the mixing tube (8) converts the mixing velocity into pressure. Additional components include a connection (1) with cock (2) for the main spray-mix tube (3) terminating in the nozzle (12) whence intermediate tube (4) leads to the mixing tube (8). Air imported via line (5) is vorticized by the nozzle groove (13) to promote air and spray mix mixing etc.
