A generally cylindrical fluid flow dampening chamber, formed at the end of the probe in communication with the spin chamber or being integrated with the spin chamber, 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 and/or in the spin chamber about the axis to effect a solid spray cone of fluid exiting the orifice.
