The Assembly comprises a centrally-bored nozzle, a centrally-bored nozzle body, a centrally-bored jet orifice element, and an orifice element-supporting cylinder, the four being in substantially collinear alignment along a longitudinal axis. The cylinder is disposed in the central bore of the body, and it too has a fluid-accommodating passage formed centrally therethrough, as well as a recess in one end in which to nest the orifice element. The cylinder has a straight shank portion which projects into a void in the nozzle body subsisting between the element and the nozzle. Adjustment screws, in penetration of the nozzle body, are arrayed about the shank portion for manipulation to adjust the attitude of the shank portion relative to the longitudinal axis and, thereby, correctively align the element with the nozzle.
