Abstract

A nozzle assembly is disclosed which includes a housing 12 having inlet opening 13 in fluid communication with at least one outlet opening 14 adapted to receive a nozzle body 42. The housing also includes a housing face 16 in surrounding relationship to the outlet opening 14. At least one indentation 18 is formed in the housing. The indentation 18 has a contoured surface 20 defined by first and second side surfaces 22 and 24 in the housing face 16 converging away from the outlet opening 14, and third and fourth side surfaces 26 and 28 in an internal wall 30 of the outlet opening 14 that converge away from the housing face 16. A nozzle body 42 may be releasably disposed within the outlet opening 14. The nozzle body 42 includes a nozzle opening 44 for ejecting a fluid and a nozzle face 46 in surrounding relationship to the nozzle opening 44. At least one indentation 38 is formed in the nozzle face 46 adjacent to, but spaced from, the nozzle opening 44. The contoured surface 20 of the housing 12 is aligned with the contoured surface 52 of the nozzle body 42 to optimize entrainment of a surrounding fluid near each housing and nozzle body indentation 20 and 52 into an ejected fluid passing through the nozzle opening 44.
