Abstract (en)
A high-pressure water delivery lance with rotary nozzle (11) comprises a cylindrical chamber (10) known as the stator, which is fed with pressurized water via at least one tangential conduit the direction of which has an axial component, and in which there rotates a nozzle (11) known as the rotor having an at least partly frusto-conical wall which rolls on the chamber surface, a sized axial hole and an end sealedly resting in an end seat of the chamber, the rotor and stator being formed of materials having between them a dynamical friction coefficient of less than 0.20. <IMAGE>
