ABSTRACT:
A fluid jetting apparatus, such as nozzle, includes a support on which an orifice member is rotatably mounted. Orifices in the member are eccentric so that fluid exiting the orifices gives a driving force to rotate the orifice member relative to the support. To prevent the member from rotating too fast, a magnetic flux is provided to induce eddy currents in the support or the orifice member to produce a resisting torque opposing the speed-increasing torque resulting from the force of the fluid exiting the orifices. The eddy currents arise in response to relative motion between the magnetic flux and either the orifice member or the support.
