Abstract:
A sprayer includes a discharge valve assembly and includes an integrated poppet valve, spring and volume reducer. The spring includes more than omega-shaped form, each with relatively flat sides. The spring can have sides with portions sufficiently wide to substantially extend across the valve chamber to provide stability to the spring and prevent buckling. The flat sided omega-form construct is relatively easy to manufacture via molding and the ends of such construction provide suitable locations for integrated molding with the valve and the volume reducer.
