A nozzle assembly 10 including a first inlet aperture 12 which receives material 14 which is to be selectively emitted from assembly 10. Assembly 10 includes an outlet aperture 16 having several apertures 18, 20, 22, 24, and 26 which are respectively separated by substantially identical elements 28, 30, 32, and 34. Elements 28-34 cooperatively form a plurality of passages or channels 40-50 through assembly 10. A centrally disposed channel 44 is relatively narrower than the other channels 40, 42, 46, and 50, and channels 42, 46 are relatively narrower than outermost channels 46, 50, thereby causing material 14 to be emitted at a substantially similar and/or uniform velocity at each point or location within outlet aperture 16.

1. A nozzle having an outlet aperture which includes a first portion having a first cross-sectional area and a second portion having a second cross sectional area which is smaller than said first cross sectional area, said nozzle further including an element which cooperates with a surface of said nozzle to form a channel; a strut which is disposed within a first end of said channel; and a blocking element which is disposed within a second end of said channel.
