Abstract
Apparatus for receiving a fluid under pressure and providing a highly cohesive fluid jet stream. The apparatus has a housing receiving fluid from a supply tube supplying fluid under pressure to the housing. The housing has a passageway therein through which the fluid flows, the passageway having an orifice therein formed by an opening in an orifice element for producing the fluid jet. The orifice element has an upstream portion, the passageway further having a converging section disposed upstream of the orifice for reducing turbulence in the passageway upstream of the orifice. The converging section extends toward the orifice element, reducing turbulence upstream of the orifice and thus providing a more cohesive fluid jet downstream of the orifice. A section having a rounded surface is disposed between the converging section and the orifice element and joins the converging section and upstream portion of the orifice element, thereby improving cohesiveness of the exiting fluid jet by further reducing turbulence upstream of the orifice.
