Abstract: A lance with swinging head (10) for high pressure cleaning equipments, includes: a tubular body (12) connected to the flexible duct coming out of said equipment on one side and,, to the other side, to a cylindrical shaped body (16) and to a nozzle (18) provided with an axial hole (42) with an end throat (42?). The body (16) is provided with an axial drilling with differentiated and increasing diameters starting from its rear end connected to the tubular body (12) towards the opposite front end (22) facing the nozzle (18) and defines, in correspondence with the front end (22) facing the nozzle (18), an annular and shaped seat housing a substantially hemispherical head (34) integral with the same nozzle, partly delimited by a ring (20) fastened to the front end (22) of the body (16).

Abstract: A lance (10) with multiple movement dispenser nozzle (44) includes a tubular body (12) provided with an axial duct (20) for the passage of the pressure water fluid; a shaped sleeve (14) matched at the front end of the tubular body (12); a rotor or rotating element (16) housed into the shaped sleeve (14), and a plate-shaped element (18) supported by a plate (22) associated to the duct (20). On the front part facing the rotor (16), the plate-shaped element (18) is provided with a shaped central recess 26 which circularly extends and having an undulated external profile from which a plurality of additional recesses (32) radially extend. The opposite rear part of the plate-shaped element (18) is provided with an integral tang (24) engaging with the plate (22).
