Nozzle |
摘要 |
This invention relates to a nozzle which is capable of selectively dispensing a liquid product as a foam or a spray. A swirl chamber delivers a vortical sheet from the nozzle orifice. The nozzle features a movable chamber which can be moved to a point where it offers no interference with the vortical sheet and thus the spray mode of delivery is effected. The chamber can be moved to a point where interference with the vortical sheet is effected and the formation of a turbulent film is realized. Gas passageways are provided to achieve aeration of the turbulent film and the resultant dispensing of the liquid as a foam.
