ABSTRACT:
Apparatus for receiving a fluid under pressure and providing a highly cohesive fluid jet stream. The apparatus has a housing for fastening to a supply tube supplying fluid under pressure to the housing. A passageway is provided in the housing through which the fluid flows, the passageway having an orifice therein for producing the fluid jet. The passageway in the housing further has a converging section disposed upstream of the orifice for reducing turbulence in the passageway upstream of the orifice, thereby providing a more cohesive fluid jet downstream of the orifice. The converging section is disposed in the housing, with the housing being a separate part from the supply tube attachable to the supply tube as a single screw-on assembly.
