| 4. A nozzle for use in a vehicle wash system comprising:
a nozzle body having a hollow interior with a peripheral wall of circular transverse cross-section;
a connector attached to the nozzle body for fluidly coupling to a source of fluid under pressure;
one or more fluid passageways extending from the connector into said hollow interior, the one or more fluid passageways forming
an acute angle with said peripheral wall so as to induce a fluid vortex within said nozzle body; and
a nozzle member including a nozzle orifice through which fluids are emitted from said nozzle, the nozzle member being substantially
contained within the hollow interior for rotation about an axis of rotation substantially in unison with the fluid vortex
during operation, said nozzle member having an outer peripheral surface that is non-circular in transverse cross-section and
engages said circular peripheral wall of said nozzle body to cause said axis of rotation to wobble and thereby slow the rate
of rotation of said nozzle member.
