Abstract:
1. A fluid spray control device that produces a variety of fluid spray patterns comprising: a housing that forms an enclosed flow path interface between a pressurized fluid source and at least one substantially cylindrical mixing cavity, said mixing cavity having a cylindrical axis and a length which is greater than diameter; a manifold within said housing that divides said fluid into at least two fluid streams that flow to at least one mixing cavity; a central flow port and at least one lateral flow port positioned on a proximal end of said at least one said mixing cavity, said central flow port that jets a first portion of said divided fluid into said mixing cavity at a trajectory substantially parallel to said cylindrical axis, and said at least one lateral flow port that jets a second portion of said divided fluid into said mixing cavity at a substantially tangential trajectory to said cylindrical axis; a control plate that interfaces with said manifold to regulate the amount of said fluid delivered to said central flow port and said at least one lateral flow port thereby regulating the ratio of said fluid delivered to said central flow port to said fluid delivered to said at least one lateral flow port during flow of said fluid spray; a cavity outlet orifice positioned approximately on said cylindrical axis of said mixing cavity that dispenses a mixture of said first portion of said fluid and said second portion of said fluid in a flow pattern which is defined by the ratio of said first fluid introduced to said mixing cavity to said second fluid introduced to said mixing cavity, said cavity outlet orifice having an opening which is less than said mixing cavity diameter; and, a reducing section within said mixing cavity that transitions said diameter of said mixing cavity to said diameter of said cavity outlet orifice.
