<p>A manually actuated pump sprayer of the type having a discharge nozzle cap in engagement with a probe, spin mechanics formed between the cap (33) and the probe. A generally cylindrical fluid flow dampening chamber (43), formed at the end of the probe in communication with the spin chamber (37) or being integrated with the spin chamber (37), has a non-smooth sidewall defined by at least one projection extending toward the axis of the probe for reducing spin energy of the fluid spinning in the dampening chamber (43) and/or in the spin chamber (37) about the axis to effect a solid spray cone of fluid exiting the orifice (36). <IMAGE></p> |
