Abstract
A nozzle assembly includes a stem and a cap. The stem includes two passages for carrying the same liquid or different liquids under high pressure. The passages terminate at a conical end surface of the stem. The cap is seated on the end surface of the stem and cooperates with the end surface of the stem to define two nozzle openings or orifices. The cap is arranged so that rotation of the cap on the stem changes the size of the orifices.
