Title: Variable spray valve assembly

Abstract: A valve assembly of the type primarily designed for use with an aerosol valve or like fluid dispenser including a valve body having movably disposed therein a valve stem sealer positioned in substantially biased, supporting engagement relative to the base of a valve stem. The valve stem is movably disposed relative to a sealing gasket and has its base portion specifically configured relative to a platform of the valve stem sealer such that substantially vertical movement of the valve stem results in either a flush engagement between the valve stem and the valve stem sealer or alternately an angular orientation therebetween. A variable spray rate of dispensing the product within the dispenser results from the product being forced through either a metering port formed between the valve stem and the valve stem sealer (low rate) or alternately directly between mating surfaces of the valve stem and the valve stem sealer when the valve stem is depressed at an angular orientation relative to the valve stem sealer as in conventional toggle action (high rate).
