Abstract:
1. A high impact liquid spray nozzle assembly comprising an elongated tubular member having liquid passageway that extends with an inwardly tapered diameter in a downstream direction along a longitudinal axis of the liquid passageway, a spray tip at a downstream end of said tubular support member having an elongated discharge orifice oriented transverse to the longitudinal axis of the liquid passageway for emitting and directing a flat liquid spray pattern, an inlet communicating with an upstream end of said tubular member liquid passageway upstream of said spray tip, a multi-stage vane section intermediate said inlet and spray tip, said multi-stage vane section comprising a plurality of vanes including an upstream vane and a downstream vane, said vanes each having a plurality of flat radial vane elements extending in radial planes through the longitudinal axis of said liquid passageway defining a plurality of longitudinally extending circumferentially spaced laminar flow passageways communicating between said inlet and said tubular member liquid passageway for directing liquid longitudinally in a direction parallel to the longitudinal axis of the liquid passageway, and said radial vane elements of said downstream vane being in circumferentially offset relation to the radial vane elements of said upstream vane.
