Abstract
A nozzle having intersecting perpendicular inlet and outlet axes is constructed with a cylindrical whirl chamber into which liquid is introduced from a transition passage. The latter is bounded by a flat surface of substantial width, with one end of the flat surface being tangent to the cylindrical surface defining the whirl chamber. In cross-section perpendicular to the flat surface and to the direction of liquid flow in the transition passage the latter is bounded by a straight flat section and a tapered down section connected to the ends of the flat section. This construction substantially reduces turbulence in the whirl chamber resulting in better controlled conical spray output for the nozzle.
Claims13
A nozzle for producing a spray directed along an outlet axis, said nozzle including a conical outlet section having a discharge orifice at its downstream end and being centered about said outlet axis, a cylindrical whirl chamber disposed at the upstream end of said outlet section and centered about said outlet axis, an inlet section disposed upstream of said chamber and having an inlet orifice centered about an inlet axis perpendicular to said outlet axis, a transition passage disposed between said inlet orifice and said chamber, in cross-section transverse to direction of liquid flow therethrough said passage including a straight main section and a remainder including a downward tapering section extending from said main section, said main section being disposed on a flat surface of said passage, said flat surface and said main section being parallel to said outlet axis, said flat surface being essentially tangent to the inner surface of the wall defining said chamber.
