Attorney, Agent or FirmInternational ClassB05B 7/24 (20060101)AbstractAn apparatus for spraying liquidous mixtures via compressed air is described. The design allows extensive use of plastic in its construction, employs a minimum of parts and allows complete assembly and reassembly with only a minimum of hand tools. The device incorporates an automatic air shut off valve that stops the flow of air upon release of the trigger, an adjustable trigger stop that ensures a uniform flow rate and a special orifice plate design that enables its quick replacement.Field of SearchHolder for carrier fluidFluid pressure discharge means Discharge from upended or tilted holder (e.g., by gravity feed to reducer) Holder coupled to gas supply source Air and liquid flow paths combine upstream of spray outlet Concentrically arranged flow paths Including handle or handgrip for supply container and attached outlet Gravity discharge hand carried PLURAL INTERCHANGEABLE DISCHARGE MODIFIERS, OUTLET ARRANGEMENTS OR COUPLING MEANS Single trigger for plural valve actuators | |
