Abstract

A nozzle body has an elongated, conical passage with the smaller end opening facing in the direction it is desired the jet to travel. At right angles thereto, a fitting in the nozzle body interconnects with a supply of pressurized water. The pressurized water enters into a manifold or plenum surrounding a chamber in which a sonic transducer is located. The manifold wall has a plurality of openings arranged in a circle for directing pressurized water into the conical chamber along each of the openings. Water from the manifold serves to fill the enclosure containing the sonic transducer to provide full fluid coupling throughout the entire interior of the jet nozzle construction. A set of fins are arranged about the walls defining the conical passage to stabilize water moving therethrough and reduce any tendency to rotate on emission.

Dependent claims

A sonic water jet nozzle, comprising:

a housing including a chamber for containing a source of sonic energy, and walls defining a plurality of substantially parallel passages lying outwardly of the first chamber, one end of each passage being in open communication with said chamber in said housing and the other end of each passage opening to the exterior of said housing;
means for interconnecting the other ends of the passage at the housing exterior to a source of pressurized fluid;
a nozzle body having a conical passage therethrough with a relatively large opening at one surface and a relatively small opening at another surface, the centerline of said conical passage being substantially parallel to said plurality of passages;
said nozzle body being interconnected with the housing such that the large opening communicates with the chamber and the plurality of passages;
and
radially extending finlike means received within said conical passage for retarding rotation of water passing through the nozzle body conical passage.
