ABSTRACT:
An improved high pressure fluid delivery system has a self-propelled swiveling action with a magnetic speed control. A magnetic rotor assembly is fixed to a rotatable spindle having a nozzle containing head through which high pressure fluid is pumped. Slight angling of the nozzles produces rotational torque which is opposed by the action of the magnetic rotor assembly, the opposition increasing at increasing rotational speeds until an equilibrium rotational speed is achieved. A cylindrically-shaped cage of the magnetic rotor assembly also supports upper and lower bearings to provide for thrust generated by high fluid pressure. The magnetic breaking effect is produced by permanent magnets.
