Nozzle contained within tubular housing. An annular manifold concentrically surrounds and abuts the outside of the housing. The manifold communicates with an external source of water. A cylindrical transducer is located within the housing. A hollow cone having an exit opening formed by a truncated vertex and an open base forms the front of the nozzle. The face of the transducer which emits ultrasonic waves is situated adjacent to the base of the cone. An annular passageway concentrically surrounds the transducer. The passageway runs axially towards the front of the nozzle before turning radially inward towards the nozzle\s centerline. The axial section of the passageway communicates with the manifold through radial ports. The section of the passageway that turns inward communicates with the base of the cone, and also directs flow of water so that its confluence is on the emitting face of the transducer. The water subsequently flows out the exit opening in a steady state column.

A nozzle comprising: an annular manifold; a tubular casing that abuts the inner diameter of said manifold and is concentric with respect to said manifold; an annular passageway that is concentric with said manifold and is located within said casing; said annular passageway being comprised of an axial section which lies parallel to the centerline of said nozzle and a radial section which runs radially inward towards the centerline of said nozzle; radial parts communicating said axial section communicating with said manifold; a hollow cone having an opening formed from a truncated vertex and having an open base; said radial section communicating with said base of said cone; and said annular passageway causing fluid flowing through said annular passageway to change direction by more than 90 degrees, and directing such fluid radially inward so that a confluence of fluid flow occurs within said nozzle.
