Abstract
A spray nozzle assembly is disclosed which includes a nozzle body having opposed inlet and outlet ends and an elongated passage extending therebetween. A fluid inlet passage communicates with the elongated passage through a side wall of the nozzle body. A member is disposed within the elongated passage and has a neck portion, a head portion, and an air passage extending therethrough. An annular chamber is defined by the elongated passage and the neck portion. The head portion cooperates with a shoulder defined within the elongated passage and has an outflow slot intersecting the air passage. Fluid is fed through the fluid inlet passage into the annular chamber, is metered into the outflow slot, and therein mixed with air emanating from the air passage.
Claims38
A nozzle assembly comprising:
- a) a nozzle body having opposed inlet and outlet ends and an elongated passage extending therebetween;
- b) a fluid inlet passage extending through a wall of said nozzle body to communicate with said elongated passage;
- and
- c) a member disposed within said elongated passage having a neck portion, a head portion depending from said neck portion, and an air passage extending through said neck portion to said head portion, said head portion dimensioned and configured to cooperate with a complementary portion defined within said elongated passage and having an outflow slot formed therein that traverses and intersects said air passage.
A nozzle assembly comprising:
- a) a nozzle body having opposed inlet and outlet ends and an elongated passage extending therebetween;
- b) a fluid inlet passage extending through a wall of said nozzle body providing fluid communication with said elongated passage;
- and
- c) a member disposed within said elongated passage having a neck portion and a head portion depending from said neck portion, said head portion having an upper tapered surface and an outflow slot formed therein which intersects said upper tapered surface, said head portion configured to cooperate with a complementary surface defined within said elongated passage, and having an air passage extending longitudinally therethrough which intersects said outflow slot.
A nozzle assembly comprising:
- a) a nozzle body having opposed inlet and outlet ends and an elongated passage extending therebetween;
- b) a fluid inlet passage extending through a wall of said nozzle body directing fluid into said elongated passage;
- c) a member disposed within said inlet end of said elongated passage, said member having a neck portion proximate said fluid inlet passage, a head portion depending from said neck portion, and an air passage extending longitudinally through said member, wherein said head portion is dimensioned and configured to cooperate with a complementary surface of said elongated passage and further includes an outflow slot that traverses and intersects said air passage;
- and
- d) a nozzle tip in fluid communication with said outlet end of said nozzle body.
A nozzle insert assembly comprising a nozzle tip having an inlet end and an outlet end with a chamber extending therebetween, said outlet end defining a discharge orifice and a generally hemispherical bottom surface, said nozzle insert assembly further including a pre-orifice member positioned proximate said inlet end of said nozzle tip for regulating the flow of fluid into said chamber, and a deflection pin disposed at least partially within a region enveloped by said generally hemispherical bottom surface proximate said discharge orifice for effecting the flow of fluid from said nozzle tip.
