konstruktionsauslegung for reservoir and beckenreinigungsvorrichtung

摘要

Constructive design for reservoir and pool cleaning device using successive and intermittent water jets, adjacent to the surface of the bottom of said reservoirs and pools, comprising a cleaning head built into said bottom, equipped with a piston (21) substantially cylindrical movable between a first lower resting position and a second operation position, in which the upper part of said piston surpasses said bottom leaving uncovered the outlet hole (29) of said jets (43), the direction of the successive jets undergoing random angular increases by means of said piston’s axial rotation at the interval of its movement between the referred positions, the momentum produced by said rotation provided only by the jet’s reaction force (43) expelled through said hole, which axel is eccentrically placed in relation to said piston’s axel.
